PEI NATURAL GRADES
JTYPEI?NA is a profile made of pure polyetherimide (PEI) material. 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.
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
JTYPEI?NA type pure PEI profiles:
● High tensile strength, the strength is above 110MPa.
● High bending strength, the strength is above 150MPa.
● Excellent thermomechanical load-carrying capacity, thermal
deformation temperature is greater than 200℃.
● Good creep resistance and fatigue resistance.
● Excellent flame-retardant performance, low-smoke combustion.
● Excellent dielectric and insulation.
