PS (Polystyrene)

PS is a colorless‑transparent thermoplastic and one of the general‑purpose plastics with relatively high transparency. Core features: good optical performance with light transmittance above 90%. Rigid and glass‑hard yet brittle, it has low impact strength and is prone to cracking. It delivers excellent processability and electrical insulation with low molding shrinkage and good dimensional stability. Its main limitations are poor heat resistance (long‑term service temperature generally ≤ 80 °C) and poor weather resistance, which makes it susceptible to aging and yellowing.

Main Applications

Daily‑use articles & packaging: widely used for disposable tableware such as plastic cups and lunch boxes, transparent CD/DVD cases, stationery (rulers, pen holders), toys and food‑packaging containers.

Electrical & electronic products: instrument housings, lamp shades, insulating films and high‑frequency capacitor components.

Construction & thermal insulation: Expanded Polystyrene (EPS, commonly known as styrofoam) is an important lightweight building material for wall thermal insulation, sound insulation and cushioning packaging materials.

Please specify your additional requirements for impact resistance, gloss level, flame retardancy, heat resistance, environmental compliance, surface pits and other physical‑property parameters.

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