High performance PPS+PPO/GF alloy for auto parts

Short Description:

Material plastic PPS+PPO/GF is a kind of special engineering plastics, known as the “new plastics for the jet age”, with excellent heat resistance, corrosion resistance and self-extinguishing and mechanical stability, is the sixth engineering plastics, the amount of special engineering plastics is the most extensive. PPS/PPO alloy has the advantages of PPS and PPO, such as high temperature resistance, chemical corrosion resistance and high mechanical and electrical properties. It also overcomes the shortcomings of PPS, such as brittle melt, low melt viscosity, difficult injection molding flash overflow, and PPO’s resistance to solvents and high melt viscosity.

PPS+PPO/GF Features

Excellent heat resistance, continuous use temperature up to 220-240 ° C, glass fiber reinforced heat distortion temperature above 260 ° C

Good flame retardant and can be UL94-V0 and 5-VA (no dripping) without adding any flame retardant additives.

Excellent chemical resistance, only second to PTFE, almost insoluble in any organic solvent

PPS resin is highly reinforced by glass fiber or carbon fiber and has high mechanical strength, rigidity and creep resistance. It can replace part of metal as structural material.

The resin has excellent dimensional stability.

Extremly small molding shrinkage rate, and low water absorption rate. It can be used under high temperature or high humidity conditions.

Good fluidity. It can be injection molded into complex and thin-walled parts.

PPS+PPO/GF Main Application Field

Widely used in machinery, instrumentation, automotive parts, electrical and electronic, railway, home appliances, communications, textile machinery, sports and leisure products, oil pipes, fuel tanks and some precision engineering products.
