Components in PTFE, PEEK, and other high-performance polymers can be used in applications that involve harsh environments and require heavy insulation.
PTFE can be used in service temperatures of up to 260°C, while PEEK can withstand up to 300°C. This makes them materials of choice in high temperature applications.
PTFE also has a breakdown voltage of up to 100Kv/mm, making it ideal in electrical insulation. Both polymers exhibit superior resistance to aggressive chemicals.
In general, polymers are increasingly preferred to metals in applications where the environment is so harsh that strength alone will not suffice. A few examples of these include:
PTFE sleeves and couplings for railway power lines
PTFE films for high-voltage capacitors
PEEK rotary seals in nuclear reactor applications
PPS bearings and bushings in pulp and paper equipment
Polyimide (Kapton) tapes for heavy electrical insulation
PTFE radomes for radar applications
PTFE shields for chemical plants
