Vespel SP-1 Polyimide sleeves PI bushing

HONYPLAS®Polyimide is commonly known as polyimide in Chinese. It is an aromatic heterocyclic polymer compound with imide chain links in its molecular structure. The English name is Polyimide (referred to as PI). Amine (PAI) and polyetherimine (PEI) four categories.Pi Polyimide Rod Sheet raw materials are one of the best heat-resistant varieties among engineering plastics. Some varieties can withstand high temperatures of 290°C for a short time and withstand high temperatures of 490°C for a short time. In addition, mechanical properties, fatigue resistance, flame retardancy, and dimensional stability , electrical properties are good, molding shrinkage is small, oil, general acid and organic solvents, not alkali resistance, excellent friction resistance, wear performance.

HONYPLAS®Polyimide characteristics

1. Mechanical properties, good fatigue resistance, and good self-lubricating properties; the tensile strength of the phenylene type polyimide film can reach 170 MPa, and the biphenyl type can reach 400 MPa

2. Wear resistance, small friction coefficient and not affected by humidity and temperature, high impact strength, but sensitive to notch.

3. Excellent heat resistance, can be used for a long time at -260 (not brittle) ~ 330oC, and the heat deformation temperature is as high as 343oC.

4. Good radiation resistance, no cold flow, no cracking, excellent electrical insulation, flame retardant.

5. Small shrinkage rate and linear expansion coefficient, good dimensional stability and low water absorption.

6. Good chemical stability, ozone resistance, bacterial erosion resistance, good solvent resistance, but susceptible to alkali, pyridine, etc.

PI plastic raw material molding method

Compression molding, dipping, injection molding, extrusion, die casting, coating, casting, lamination, foaming, transfer molding.

Polyimide Sheets Pi application fields

PI materials are used in aviation, automobiles, electronic appliances, industrial machinery, etc., and can be used as engine fuel supply system parts, jet engine components, compressor and generator parts, fasteners, spline joints and electronic connectors. Used in automotive engine parts, bearings, piston sleeves, timing gears, printed circuit boards, insulating materials, heat-resistant cables, terminals, sockets in the electronics industry, high temperature resistant self-lubricating bearings, compressor blades and piston machines in the mechanical industry , Seal rings, equipment heat shields, thrust washers, bushings, etc. High temperature resistant self-lubricating bearings, compressor piston rings, tobacco machinery parts, printer automation parts, jaws, gaskets, bushings and other fields.
