That sets you up for success, ensuring your parts perform exactly as expected. At PADT, we prioritize matching materials to specific project requirements to ensure reliable, high-quality results.
If you are looking for more details, kindly visit our website.
In this post, we’ll explore two of our in-house 3D printing technologies, FDM (Fused Deposition Modeling) and P3 DLP (Programmable PhotoPolymerization), and compare our high-temperature material options available for each. You’ll get an overview of the strengths, limitations, and ideal applications for each material, helping you choose the right technology for your project.
FDM, which most people are familiar with, builds parts by melting thermoplastics layer by layer. FDM also offers a broad range of high-temperature material options, making it very popular in the aerospace, automotive, and electronics industries.
Here’s a closer look at some of the high-temperature FDM materials we offer:
PLA (Polylactic Acid) is a biodegradable plastic and very popular in FDM printing due to its low cost and availability, especially in this economy. However, PLA has a lower heat resistance compared to the other materials, with a heat deflection (HDT) of 124°F (51°C). Therefore, it’s best suited for prototypes, low-stress applications, and any projects where thermal performance isn’t life or death.
ABS-M30 is a little more versatile than PLA, offering higher impact resistance and better durability. With an HDT of 204°F (96°C) and a glass transition temperature (Tg) of 226°F (108°C), ABS-M30 is often used for functional prototypes, manufacturing tools, and end-use parts in automotive and consumer products where thermal performance and mechanical strength are required. We also offer ABS in several colors: Natural, White, Black, Blue, Red, and Gray.
Ultem and Ultem are known for their high strength, excellent chemical resistance, and flame retardancy (UL94-V0 rated), making Ultem ideal for aerospace and automotive applications, where parts must meet strict safety and performance standards. When choosing between the two, consider:
Antero, also known as Polyetherketoneketone (PEKK) polymers, is known for its superior thermal and mechanical performance as well as Electrostatic Discharge (ESD) resistance for CN03. When choosing between these two, consider:
P3 uses UV-curable resins, an evolution of Digital Light Processing 3D printing. Light, temperature, pull forces, and pneumatics are tightly controlled during the printing process, resulting in injection-molded-like surfaces with amazing dimensional accuracy. It’s well suited for producing parts with fine details and tight tolerances.
Below is a comparison of our high-temperature P3 materials offered at PADT:

With an HDT of 324°F (162°C) and an ultimate tensile strength (UTS) of 85 MPa, it’s a good choice for parts that need to withstand high mechanical loads and elevated temperatures. However, its low elongation at break (0.7%) means it is better suited for rigid, load-bearing applications rather than those requiring flexibility. Thus, making it ideal for functional prototypes and end-use parts in industries like automotive.
BASF B FR is a flame retardant material specifically designed for applications requiring both heat resistance and compliance with fire safety regulations. With an HDT of 305°F (152°C), it performs well in high-temperature environments. Although it doesn’t have the same mechanical strength as BASF RG, its UL94-V0 flammability rating makes it ideal for industries such as aerospace and transportation. Also, to note, its elongation at break of 4% offers more flexibility than some of the other high-temperature materials.
P3 Deflect 120 has an HDT of 200°F (93°C) and a tensile strength of 100 MPa, offering a good mix of strength and heat resistance. It’s a good option for functional parts that require higher mechanical performance while also operating in higher-heat temps. It’s 4% elongation at break also provides some flexibility, which can be useful in parts subject to mechanical stresses. This makes it a good choice for end-use applications in electronics housings and industrial tooling.
Loctite FST is an excellent material for high-heat and flame-resistant applications, with an HDT of 417°F (214°C)—the highest among the P3 materials. Its combination of high thermal resistance and low smoke and toxicity emissions, including a fire safety rating of UL94-V0 makes it an excellent choice for parts used in the aerospace, transportation, and rail industries. With an elongation at break of 2.1%, it’s more rigid than some of the other P3 materials, making it ideal for applications where parts must maintain their shape and integrity under both high temperature and flammability requirements.
Mechnano CLiteB uses carbon nanotube (CNT) technology to enhance mechanical performance and electrical conductivity. Although it doesn’t have specific heat deflection data available, it features a strength of 65 MPa and a 3.2% elongation at break, providing a balance of rigidity and flexibility. Since it’s also suitable for electrostatic discharge (ESD) applications, protecting sensitive electronic components, it’s great for electronics, aerospace, and industrial applications.

Maximizing Durability and Efficiency with the Right Temperature-Resistant Materials
Have you ever wondered why some plastics can withstand higher temperatures while others cannot? Or why certain plastics are recommended for specific applications over others? The key lies in the plastics operating temperature of the plastic material.
The operating temperature of a plastic material is a crucial factor that determines its functionality and longevity. It refers to the maximum temperature range within which the plastic can function optimally without degrading or breaking down.
This blog post will delve into the world of plastics and their plastics operating temperatures. We will explore the concept of operating temperature, how it is measured, and the factors that influence it. We will also discuss different types of plastics and their respective plastics operating temperature ranges, as well as provide tips on how to select the right plastic based on its plastics operating temperature. Finally, we will share some real-world examples of successful applications of plastics in various temperature ranges.
For effective use of plastics across various applications, it is imperative to comprehend their operating temperature. The operating temperature refers to the maximum operating temperature range within which the plastic can function without degradation, embrittlement, or breakdown. The performance and longevity of plastic materials are directly influenced by their operating temperature. If a plastic is subjected to temperatures outside of its optimal range, it can experience degradation, increased brittleness, or breakdown, leading to compromised functionality and reduced service life.
The primary factors that contribute to the operating temperature of plastics include material properties such as distortion, softening, expansion, and glass-transition temperature, as well as considerations like service life, melting point, degree of crystallinity, time and rate of temperature exposure, and part geometry.
The performance of plastic materials is significantly impacted by the operating temperature. It is defined as the maximum ambient service temperature that a material can endure without experiencing significant degradation or loss of mechanical properties. As the temperature rises, the mobility of the amorphous regions of plastic materials increases, thereby affecting their performance. If plastic materials are utilized beyond their designated temperature range, they may undergo alterations in their characteristics.
For instance, elevated temperatures can cause the amorphous regions of the plastic to become mobile, potentially impacting its strength and flexibility. Conversely, excessively low temperatures can also affect plastic materials. The operating temperature range for plastic materials is determined through rigorous testing and precise measurements. Factors like softening and loss of stiffness are taken into account when establishing the operating temperature range.
Several factors play a role in determining the operating temperature of a plastic material. Some of these factors include:
These factors, among others, contribute to the overall operating temperature of a plastic material.
Processing methods, such as melting temperature, melt mold temperature, and other conditions, also play a significant role in influencing the operating temperature of plastics. Additionally, environmental conditions, such as ambient temperature, have a substantial influence on the operating temperature of plastics.
Various methods and standards are used to measure operating temperature. The Maximum Service Temperature refers to the highest temperature at which a material can be utilized without experiencing significant loss of its mechanical or electrical properties throughout the reasonable lifetime of the product. This temperature is determined through continuous use temperature measurement in degrees Celsius or Fahrenheit, in conjunction with references to tables that offer the maximum use temperature for various plastic types.
Continuous Use Temperature, on the other hand, refers to one of the two temperatures at which a plastic material can operate without experiencing changes in its properties, demonstrating its ability to sustain long-term performance under thermal stress. The Relative Thermal Index (RTI) serves as a metric for determining the highest operational temperature, measured in degrees centigrade, for a plastic, ensuring that specific essential properties remain within acceptable limits. This standardized measure facilitates the comparison of heat resistance among various plastic materials.
Maximum service temperature is defined as the highest temperature at which a material can be used without significant loss of properties. It is established based on the form of supply according to EN : and EN : + A1:. The insulation layer thickness can only decrease by 5% of its original value at its maximum service temperature. This requirement ensures the effectiveness and safety of the insulation. The ASTM D794 test is utilized to ascertain max temperature.
In plastics, the continuous use temperature is the point at which the polymer starts to degrade, embrittle, and break down over time. This differs from maximum service temperature, which is the highest temperature at which a material can operate temporarily without significant degradation of mechanical or electrical properties. Techniques used to ascertain the continuous use temperature of plastic include the Relative Thermal Index (RTI) test, UL 746 calculation, and mechanical tests such as Heat Deflection Temperature (HDT) and Vicat softening.
The factors that influence the continuous use temperature include:
When subjected to temperatures beyond their continuous use temperature, plastics may undergo a reduction in strength and stiffness, and may exhibit increased brittleness and susceptibility to hardening, particularly in extremely cold environments.
Based on property loss, the Relative Thermal Index (RTI) serves as a comparative measure of a material’s continuous use temperature. The indication provided by this is the temperature at which a material can undergo aging for 100,000 hours. It also ensures that at least half of the initial property being measured is maintained. The RTI is determined by assessing the deterioration of properties in the plastic material as it is subjected to a maximum continuous use temperature over time.
Specifically, the RTI measures the electrical insulation properties of the material. The established industry guidelines for quantifying RTI entail subjecting a material to a sequence of incrementally elevated temperatures and evaluating its electrical insulation properties using a test method.
Operating temperature ranges vary among different types of plastics. For instance, thermoset plastics such as polyurethane, epoxy, and phenolic are known for their ability to withstand high temperatures. In very high temperature applications, materials like polyimides, which can reach up to 550–600 °F, are commonly utilized.
On the other hand, thermoplastics exhibit a broader operating temperature range in comparison to thermoset plastics, allowing them to endure different temperatures within the range of -200°C to +260°C. This provides versatility for utilization across a wider array of applications.
Significant differences in properties and uses exist between thermoset plastics and thermoplastics. A thermosetting plastic is characterized as a polymer that irreversibly solidifies when subjected to heat. In contrast, a thermoplastic is defined as a type of plastic composed of polymer resins that soften when heated and solidify when cooled.
Thermoset plastics exhibit a higher level of durability at high temperatures due to their inability to be remolded or reheated after the initial forming, thus maintaining their shape.
Mingte supply professional and honest service.
In contrast, thermoplastics have the capability to be reheated and remolded after the initial forming process. For instance, PTFE (Teflon) has a range from -200°C to +260°C, PE-UHMW can range from -260°C to +80°C, and polycarbonate has an ideal thermoforming temperature range of about 300 to 500°F.
Typically, thermoset materials generally exhibit higher Relative Thermal Index (RTI).
Low operating temperature thermoset composites encompass materials such as CE, G10, and FR4, specifically engineered for use in environments with temperatures typically not exceeding 140°C (284°F).
CE thermoset composites exhibit:
High operating temperature thermoset composites display the following characteristics:
In particular, G11 thermoset composites demonstrate enhanced mechanical strength at elevated temperatures compared to G10, illustrating their ability to effectively endure high operating environments.
