Polyimid-Folie

Polyimide is molecular structure containing imide base chain section of the aromatic heterocyclic polymer compound, can be divided into both benzene type PI, soluble PI, polyamide - imide) (PAI) and polyether imine (PEI) four categories. PI is currently engineering plastics in one of the best breed of heat-resistance, some varieties can bear high temperature290 °C short time under the high temperature, in addition 490°C mechanical performance, fatigue resistance and flame retardant sex, dimension stability, electric performance is good, molding shrinkage of small, oil resistance, general acid and organic solvents, alkali not, which has excellent resistance to abrasion performance. PI friction, shaping method including the compression moulding, dipping, injection, extrusion and die-casting, coating, flow delay, laminated, foaming, transfer molding. Application PI in aviation, automotive, electronics, industrial machinery, etc, can make the engine has applied for fuel system components, the jet engine components, compressor and generator parts, fastener, spline joint and electronic contact device, also can be used as automobile engine parts, bearings, piston sets, timing gears, electronic industry do printed circuit board, insulation materials, heat resistant cable, terminals, socket, machinery industry on high temperature resistant lubricated bearings, compressor blades and piston machine, sealing ring, equipment heat insulation cover, thrust washers, target group-exact marketing etc.
