PPS (Polyphenylene Sulfide)

Plastic

PPS is a high-performance engineering plastic known for its excellent chemical resistance, high temperature resistance, and mechanical strength. The material retains its shape and properties even under extreme conditions, making it ideal for applications in aerospace, automotive, and electronics. PPS is also flame retardant and highly dimensionally stable.
Well-known trade names for PPS include Ryton®, Fortron®, Tecatron®, and Torlon® (in blends). These grades are often chosen for critical parts that are exposed to heat and aggressive chemicals for extended periods.

Properties of PPS

Very high temperature resistance (up to 260 °C continuous)
Excellent chemical resistance, even to acids and alkalis
Flame retardant without addition of halogens
High dimensional stability and low thermal expansion
Good electrical insulating properties, even at high temperatures
Wear-resistant and hard material with low coefficient of friction
Minimal moisture absorption
Good resistance to creep and stress corrosion
Suitable for precision components in demanding environments

This combination of properties makes PPS a popular choice for applications where conventional plastics fall short.

Frequently asked questions about PPS

Is PPS suitable for high temperatures?

Yes—PPS remains stable up to 260 °C and deforms minimally even under prolonged load.

What are the chemical properties of PPS?

PPS is highly resistant to acids, alkalis, solvents, and fuels—more so than most plastics.

Can PPS be milled?

Absolutely. PPS machines very well, yielding a clean surface finish and high dimensional accuracy.

Is PPS electrically insulating?

Yes—PPS has excellent dielectric properties, even at elevated temperatures or in humid conditions.

How does PPS differ from PEEK?

PPS is less expensive than PEEK and offers superior chemical resistance, but is somewhat more brittle and has lower impact strength.

Is PPS food-safe?

Some grades are FDA-approved; always verify the specification if you need food-contact certification.

Can PPS be used outdoors?

Although PPS is reasonably UV-resistant, it is typically protected or modified for long-term outdoor use.

What are typical applications for PPS?

Primarily in automotive, aerospace, and electronics, where temperature resistance, dimensional stability, and chemical resistance are crucial.
