PEI cast film production line

Polyetherimide (PEI for short) is an engineering plastic made of amorphous polyetherimide with high temperature resistance and dimensional stability, as well as chemical resistance, flame retardancy, electrical properties, high strength, high rigidity and so on. PEI resin can be widely used in high temperature resistant terminals, IC chassis, lighting equipment, FPCB (flexible circuit board), liquid transport equipment, aircraft interior parts, medical equipment and household appliances.

GWELL customises high temperature extrusion cast film production lines for PEI and PES materials on a non-standard basis. The equipment has good plasticisation, uniform film thickness, thickness can be controlled at about 10%, no black spot, sticky folding. Film width 650mm thickness 0.01-0.1mm.
