GPPS

General-purpose polystyrene (crystal)

GPPS is one of the most economical thermoplastics: glass-clear, stiff and easy to process. It is brittle, so it serves thin-walled products that see no impact. Disposable cups, CD cases, cosmetic packaging, laboratory consumables and foam (EPS) feedstock are typical uses.

Overview

GPPS is the standard grade of the GPPS family in the general-purpose plastics group. It is used in applications such as clear disposable containers and cups, petri dishes and lab consumables, cosmetic and stationery packaging. The grade with the right flow for injection, extrusion or another process is specified in the quotation together with your quantity and colour; TDS and SDS are sent with the quotation.

Tensile strength is measured to ISO 527, melt flow rate to ISO 1133, heat deflection temperature to ISO 75 (1.8 MPa); flammability class per UL94. Depending on supplier and grade, values can fall outside this range.

Applications

  • Clear disposable containers and cups
  • Petri dishes and lab consumables
  • Cosmetic and stationery packaging
  • Lighting diffusers

Documents

The supplier's technical data sheet (TDS) and safety data sheet (SDS) for GPPS are sent by e-mail with the quoted grade; because the same code has different sheets at different suppliers we do not publish a single file on the site. To see the sheet in advance, request it with the link below.
