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 of 200‑240 °C and heat‑deflection temperature over 260 °C. It features superior chemical resistance, practically insoluble in any solvent below 200 °C and highly resistant to acid‑alkali corrosion. It is intrinsically flame‑retardant and reaches UL94‑V0 grade without additional flame‑retardant additives. It also delivers outstanding dimensional stability (molding shrinkage ＜0.0025 %) and excellent electrical properties. Unmodified PPS resin is brittle and generally modified with glass‑fiber or other fillers.

Main Applications

Automotive industry (largest application field, approx. 43%): new‑energy‑vehicle motor components, electronic water‑pump housings, lithium‑battery covers, achieving over 30% weight reduction compared with 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 200 °C acidic flue gas.

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.
