PS (Polystyrene)

PS is a colorless‑transparent thermoplastic, one of the general‑purpose plastics with relatively high transparency. Core features: favorable optical performance with light transmittance over 90%. Rigid and brittle, it is glass‑hard but features low impact strength and tends to crack easily. It delivers excellent processability and electrical insulation with low molding shrinkage and good dimensional stability. Its main drawbacks are poor heat resistance (long‑term service temperature generally not exceeding 80 °C) and unsatisfactory weather resistance, which makes it susceptible to aging and yellowing.

Main Applications

Daily‑use articles & packaging: widely applied 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.

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.
