High Temperature Resistance PPA Glass Fiber Polymer Wide Applications

Fiber-reinforced PPA has high temperature resistance, high strength and low density, so it is considered the best resin to replace steel with plastic.

It can be used in many industrial and civil fields, including automobiles, equipment, entertainment, food processing, communications, electronics and electrical , power tools, gardening, etc.

Automotive applications account for 80% of total usage, with a major trend being the replacement of metal in modular components such as front-end components and door components.

Currently in Europe, this type of material has become a standard material for front-end brackets, door components, dashboard brackets, underbody protection parts and other structural parts.

Long Carbon Fiber vs. Short Carbon Fiber Composites

Applications
PPA (Polyphthalamide) reinforced with long glass fiber:
Automotive structural components – such as engine covers, water pump housings, oil separators, where heat resistance and mechanical durability are critical.
Electrical connectors and components – especially in areas that require high thermal and mechanical performance.
Industrial parts – such as gears, bearing housings, and power tool housings, for use in high-load and moderate to high-temperature environments.
Metal replacement – for lightweight yet strong alternatives in technical applications.

PPS (Polyphenylene Sulfide) with long glass fiber reinforcement:
Automotive electrical and sensor housings – especially in high-temperature or chemically aggressive environments.
Electrical and electronic components – such as switches, sockets, and coil bobbins requiring heat resistance and insulation.
Chemical processing equipment – including pump parts, seals, and pipe fittings, where resistance to acids, bases, and steam is necessary.
Fluid systems and medical components – ideal for applications requiring high dimensional stability, chemical inertness, and long-term reliability.
