PPS (Polyphenylene Sulfide)

Known as “plastic gold”, PPS is a high‑performance special engineering plastic. Core features: excellent high‑temperature resistance with long‑term service temperature ranging from 200‑240 °C and heat‑deflection temperature above 260 °C. It possesses outstanding chemical resistance, barely soluble in any solvent below 200 °C and highly resistant to acid and alkali corrosion. It is intrinsically flame‑retardant and reaches UL94‑V0 rating without added flame‑retardant agents. It also delivers superior dimensional stability (molding shrinkage ＜0.0025 %) and good electrical properties. Unmodified PPS resin is brittle, so modification with glass fiber and other fillers is generally required.

Main Applications

Automotive industry (the largest application sector, approx. 43 %): new‑energy‑vehicle motor components, electronic water pump housings, lithium‑battery covers, achieving over 30 % weight reduction by replacing metal parts.

Electrical & electronic industry (approx. 24 %): micro‑connectors, coil bobbins, 5G base‑station antenna vibrators with low dielectric loss.

Environmental protection: high‑temperature filter bags for coal‑fired power plants, resistant to acidic flue gas at 200 °C.

Aerospace: aircraft components and missile structural parts.

Machinery & chemical industry: corrosion‑resistant parts such as pump bodies, valves and sealing elements.

Please specify your additional requirements for impact performance, tensile properties, flexural properties, elongation at break, environmental compliance and other physical‑property parameters.

MOQ: 1 ton upon successful sample testing. After‑sales: return and replacement for quality‑related defects.
