Polyphenylene Sulfide (PPS) plastic is a high-performance thermoplastic polymer designed to meet the most rigorous demands. It’s exceptionally strong, resistant to fire & high temperatures, and has excellent electrical insulation properties. Developed in 1967, PPS plastics remain a popular choice for anyone needing durable plastic that can withstand a range of environments and applications.

If you need this material for your company’s current or upcoming projects, order fabricated PPS plastic from Polymershapes in Los Angeles. Our ISO 9001-certified company offers the premium quality plastic materials you need for your project.

The Benefits of Polyphenylene Sulfide

When sodium sulfide and dichlorobenzene combine using polar solvents, this process creates polyphenylene sulfide plastic. The result of this high-temperature fabrication process creates one of the most resistant and durable plastics.

This semi-crystalline material is beneficial for its:

    • High dimensional stability
    • Superior mechanical strength (even at temperatures near 392°F)
    • Excellent strength-to-weight ratio
    • Broad chemical resistance
    • Corrosion and creep-resistant
    • Insulation against electricity

There are three main types of polyphenylene sulfide plastic to suit the needs of any project.

Linear PPS offers a higher molecular weight than standard PPS. Heating traditional PPS with air present creates cured PPS. Lastly, branched PPS is another popular option for its enhanced strength.

Industries Relying on Polyphenylene Sulfide (PPS) Plastic

This high-performance plastic is commonly used in some of the most demanding industries, including:

Electronics Manufacturers: PPS is commonly used in electronics manufacturing to produce heat shields, contact rails, connectors, and contact pressure discs. The stability of PPS plastic also makes it a stable material for soldering purposes.

Automotive: Thanks to its high mechanical strength and chemical resistance, PPS is a popular choice for under-the-hood plastic parts. You’ll find polyphenylene sulfide plastic used in fuel and brake systems. Motor vehicle companies also use this material for automotive parts that must withstand excessive temperatures, mechanical stress, or fluids in an automobile.

Chemical Producers: PPS is commonly used for nozzles, pumps, valves, and fittings—often used by chemical companies.
Medical and Healthcare: Depending on many tools and equipment, the medical industry also relies on polyphenylene sulfide (PPS) for instruments that must remain stable in heat-sensitive environments.

Appliance Manufacturing: You’ll also find this material extensively used throughout the appliance manufacturing industry. Common uses of this plastic for appliance parts can include dryer grills, switches for toasters or dryers, and turntables for microwave ovens.
