PPS (Polyphenylene Sulfide)

Known as “plastic gold”, PPS is a high‑performance special‑engineering plastic. Core features: outstanding high‑temperature resistance with long‑term service temperature of 200‑240 °C and heat‑deflection temperature above 260 °C. It acts as a reliable chemical shield, practically insoluble in all solvents below 200 °C and highly resistant to acid‑alkali corrosion. It is inherently flame‑retardant and achieves UL94‑V0 rating without flame‑retardant additives. It also features excellent dimensional stability (molding shrinkage ＜0.0025 %) and superior electrical properties. Unmodified PPS resin is brittle, so glass‑fiber or other reinforcing fillers are commonly adopted for modification.

Main Applications

Automotive industry (largest application field, approx. 43 %): new‑energy‑vehicle motor components, electronic water‑pump housings, lithium‑battery covers, delivering more than 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 up to 200 °C.

Aerospace: aircraft components and missile structural parts.

Machinery & chemical industry: corrosion‑resistant components including pump bodies, valves and sealing parts.

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.
