PEI SPECIAL GRADES
JTYPEI?GF30?is a 30% chopped glass fiber reinforced polyetherimide
(PEI) profile. PEI is an amorphous polymer with a glass
transition temperature of up to 215°C. It has mechanical properties
equivalent to PEEK, as well as excellent heat resistance,
insulation properties, and flame retardancy. Compared with
unreinforced polyetherimide (PEI) materials, this product has a
certain improvement in material strength and modulus, better
wear resistance, and a smaller thermal expansion coefficient.
The product can be used in environments with high stress, fatigue
stress or impact stress in high temperature environments, such as
auto parts or interior and exterior decoration, semiconductor
processing, precision bearings, mechanical load-bearing components,
wind power equipment or new energy battery components,
electrical system.
Product Features
