Unplasticised Polyvinyl Chloride - Unplasticised PVC - UPVC Structural Foam

Polymer Type

Thermoplastic

Advantages

Components with excellent stiffness to weight properties can be manufactured. Thick parts with no sink marks possible.

Disadvantages

Surface finish is not high. Reduced tensile strength, modulus, elongation at break, impact characteristics and HDT compared with PVC.
