I. Heat-resistant plastics

1. PEEK

PEEK (polyether ether ketone) is one of the most popular heat-resistant plastics. PEEK plastic can withstand temperatures up to 260°C (500°F). It is commonly used in applications such as medical devices, automotive components, and aerospace parts.

PEEK is known for its excellent mechanical strength, resistance to chemicals and hydrolysis. It is also low flammability and radiation resistant, making it ideal for applications requiring durability and reliability.

In the medical field, PEEK is commonly used in implants and medical devices due to its biocompatibility and radiolucency. In the aerospace industry, it is used in parts that require high strength and lightweight properties.

2. PPS

Polyphenylene sulfide (PPS) is a high-performance engineering thermoplastic, known for its exceptional heat and chemical resistance. It is a semi-crystalline polymer that offers a combination of high strength, stiffness and dimensional stability, making it ideal for many applications. PPS plastic can withstand a maximum temperature of 218°C (424°F).

PPS is commonly used in industries such as automotive, electrical and industrial, where resistance to chemicals, solvents and temperature is highly valued. It is commonly used in the manufacture of components for fuel systems, electrical connectors, and industrial equipment.

One of the main advantages of PPS is the ability to maintain its properties at high temperatures. Additionally, PPS has excellent resistance, making it a reliable choice for parts subject to repeated stress.

3. Polyimide

Polyimide is another heat-resistant plastic widely used in high-temperature applications. These materials can withstand temperatures up to 400°C (752°F) and are commonly used in the aerospace industry for insulation, as well as in electronics and automotive applications. A typical type of Polyimide is Katon plastic.

One of the main advantages of polyimide is its thermal stability, making it an ideal material for applications requiring high temperature resistance. It also has good chemical resistance, making it suitable for use in corrosive environments.

Polyimide is commonly used in the manufacture of flexible printed circuit boards, insulating wires and cables, as well as as coatings for various electronic components. High strength and excellent dielectric properties make it a popular choice for these applications.

In addition to industrial applications, polyimide is also used in the production of high-performance films, adhesives and coatings. Its versatility and durability make it a valuable material in many industries.

4. Liquid crystal polymers

Liquid crystal polymer (LCP) is a unique material that exhibits both polymer and liquid crystal properties, also known for its heat resistance, LCP is capable of withstanding temperatures up to 300°C ( 572°F). LCP is commonly used in high-temperature electrical and electronic applications, as well as in automotive and industrial components.

5. Other heat-resistant plastics

In addition to the specific types of heat-resistant plastics above, there are many other types of materials with varying degrees of heat resistance, such as:

Polyetherimide (PEI): withstands temperatures up to 180°C (356°F).
Polyphenylsulfone (PPSU): withstands temperatures of 180°C (356°F).
Polytetrafluoroethylene (PTFE): has operating temperatures ranging from -200°C to 260°C (-328°F to 500°F).
Polyetherketone (PEK): has an operating temperature ranging from -180°C to 260°C (-300°F to 500°F).
