PVC-U (HardPVC) is an amorphous thermoplastic with no added plasticizer. It has high hardness and rigidity. According to DIN 16 927 the material is classified as normal shock resistant, however its toughness values border on being rated as highly shock resistant, which gives it a high degree of safety in regards to the design of components. PVC-U is a flame retardant material with an exceptional chemical resistance and also lower stress cracking. It shows high mechanical strength, tensile strength and works with a continues operating temperature of -15°C to +60°C. It can be easily glued and welded.
PVC-U is not subject to any major sliding abrasion and is thus not suitable for use in sliding applications.
PVC-U is resistant to acids, alkaline solutions, alcohols, oils, fats, aliphatic hydrocarbons and petrol.
PVC-U is not resistant to benzol, chlorinated hydrocarbon, ketones or esters. In combination with strong oxidizing materials (e.g., nitric acid or chromic acid), there is a danger of stress corrosion cracking.
Color: Grey (RAL 7011)
Applications – Pump parts, fittings, valve bodies, component parts in chemical plant construction, feed tables, machine and equipment coverings, gaskets, bearing cages, pipes liners, lamp boxes etc..
