PVC-u Engineering PlasticPVC-u

Flame Retardant, Chemical Resistant, Engineering Plastic

PPVC-u (u = unplasticised, or rigid PVC) is a flame retardant material with exceptional chemical resistance and low stress cracking. PVC-u shows high mechanical strength for continuous operating between -15°C and +60°C.


PVC-u machines well but ensure the machining area is well ventilated, or extracted, as PVC-u will give off chlorine if accidently over-heated. Full machining instructions are available on request.

Chemical Resistance

PVC-u has a very good resistance to acids (except strong, oxidising acids), alkalis and hydrocarbons (except chlorinated hydrocarbons). It has limited resistance to aromatic compounds and should not be considered in contact with ketones or hot water.
