Which High-Temperature Plastic is Right for My Application?

High temperature plastics

The strongest ceramics can withstand upwards of 1,600 F, but they can also shatter upon impact or if they undergo dramatic temperature changes.

Metals can withstand extremely high temperatures—but they’re vulnerable to corrosion.

Need a material that stands up to high temperatures without sacrificing other properties? That’s where high-temperature plastics come in.

Plastics that can exceed 300° F in continuous operating temperature are usually classified as “high-temperature.” While each offers incredible resistance to heat, applications vary widely due to variations in chemical resistance, strength, wear-resistance, electrical properties, etc.

In this blog, we’ll review a few popular high-temperature plastics and the properties that make them exceptional.

5 High-Temperature Plastics You Should Know About


Common applications of VESPEL take place in hostile and extreme environments. It’s mostly used in aerospace, semiconductor and transportation technology.


PEEK has become a popular material for medical devices in recent years, due to its advanced properties that make it uniquely suitable for contact with the human body. Nevertheless, it’s commonly used in the aerospace, automotive, oil & gas, and electronics industries as well.


Essentially, Torlon offers Nylon’s room-temperature strength at much higher temperatures. Common applications include mechanical and structural components, aircraft hardware, transition components, and various coatings, composites and additives.

Celazole PBI

This advanced high-temperature plastic is transforming the semiconductor, aerospace and telecommunications industries. The substitution of Celazole PBI for other materials can reduce costly breakdowns while improving efficiency.

Rulon (various reinforced PTFE compounds)

Rulon materials are finding widespread use in bearing and seal applications at temperature extremes. Rulon also withstands a variety of harsh environments such as cryogenic temperatures, water, extreme dryness, steam and hydrocarbon fuel.
