Materials Used In Producing Plastic Valves

Plastic valves are made from plastic materials and are used in applications that require corrosion resistance and/or chemical handling.

There are many materials used in producing plastic valves.

Acetal polymers offer excellent lubricity, fatigue resistance, and chemical resistance.

Polyvinyl Chloride (PVC) provides good flexibility, smooth surfaces, and nontoxic qualities.

Chlorinated PVC (CPVC) is suitable for high temperature applications and is used in hot water distribution.

Polytetrafluoroethylene (PTFE) exhibits a high degree of chemical resistance and a low coefficient of friction.

Polyethylene (PE) is a soft, flexible and tough plastic with outstanding electrical properties but poor temperature resistance. It is prone to stress cracking and has poor resistance to ultraviolet (UV) light.

Polyproylene (PP) is similar to PVC, but can be used in exposed applications because of its resistance to UV, weathering and ozone.

Polyvinylidene fluroride (PVDF) has good wear resistance and excellent chemical resistance, but does not perform well at elevated temperatures.
