General Information

PEI is an amorphous thermoplastic of high resistance able to withstand constant temperatures of up to 170 ºC, in addition to having excellent flame resistance (UL 94 V-O)and low smoke generation. It is an ideal material in applications that require good resistance to high temperatures or that require excellent electrical insulation properties. It is resistant to hydrolysis, and highly resistant to a wide range of chemical products. PEI is also resistant to gamma rays. It is excellent in reusable medical instruments that require repeated sterilisation. PEI reinforced with fibreglass produces a product with excellent resistance-drag properties and resistance to incremental stress with even greater rigidity and dimensional stability and lower cracking than ordinary PEI. It has good resistance to impact, although a low pressure chemical attack could lead to rupture.
