Polyethylene (PE): Polyethylene exhibits good chemical resistance, electrical insulation, and low friction coefficient. It is commonly used to manufacture gaskets, seals, pipes, and storage tanks.

Polypropylene (PP): Polypropylene offers excellent chemical stability, heat resistance, and mechanical strength. It is commonly used to manufacture chemical containers, valves, and pumps.

Polyvinyl Chloride (PVC): PVC is a common plastic material known for its good corrosion resistance and electrical insulation properties. It is frequently used to manufacture pipes, valves, and cable protective sleeves.

Polytetrafluoroethylene (PTFE): PTFE is a plastic material with excellent chemical corrosion resistance and high-temperature resistance. It is commonly used to manufacture seals, gaskets, and lubrication materials.

Polyimide (PI): Polyimide exhibits high-temperature stability, mechanical strength, and electrical insulation. It is commonly used to manufacture high-temperature seals, electronic components, and insulation materials.

Polyamide (PA): Polyamide offers excellent strength, stiffness, and wear resistance. It is commonly used to manufacture gears, bearings, and mechanical parts.
