PPS (Polyphenylene Sulfide)

Known as “plastic gold”, PPS is a high‑performance special engineering plastic. Core features: outstanding heat resistance with long‑term service temperature of 200‑240 °C and heat‑deflection temperature above 260 °C. Excellent chemical resistance, barely soluble in any solvent below 200 °C and highly resistant to acid and alkali corrosion. It is inherently flame‑retardant and achieves UL94‑V0 rating without extra flame‑retardant additives. It also provides exceptional dimensional stability (molding shrinkage ＜0.0025 %) and favorable electrical properties. Its main weakness is brittleness of neat resin; glass‑fiber and other fillers are commonly applied for modification.

Main Applications

Automotive industry (largest application field, ~43 %): new‑energy‑vehicle motor components, electronic water‑pump housings, lithium‑battery covers, realizing over 30 % weight reduction versus metal parts.

Electrical & electronics (~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 acid flue gas up to 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 recycled PPS pellets: color, impact performance, tensile properties, flexural properties, elongation at break, environmental compliance, surface defects and other physical‑property parameters.

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