PVC-U (Hard PVC) is an amorphous thermoplastic with no added plasticizer. 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. It has high hardness and rigidity.
