Materials (property) Chemical Resistance Weathering resistance (Electrical) characteristics and Physiological , UPVC piping systems are produced w/o plasticizers and fillers, However for injection moulding purposes lubricants are added to assist in process of production of complex parts, and to combat the effects like Ultra Violet light, stabilisers are added. UPVC is produced by the polymerisation of vinyl chloride, a gaseous monomer.

Technical products manufactured from PVC-U can have a monomer content of 0.1ppm, which is considerably less than the specified limits. Owing to the high chlorine content of PVC-U, it does not support combustion after removal of a flame, and thus PVC-U falls into the class V-0 according to UL94.
