Materials and their Characteristics # 1982 York
Exposure df UPVC systems in storage and service leads to changes in physical properties with increased exposure periods. A programme of external exposure and artificial accelerated exposure has been undertaken and changes to surface gloss, low speed mechanical properties and colour development monitored.

Nationally moderated and approved competency training Units and Qualifications have been established in Australia for plastics pipes within an overall Plastics Industry Training Package. Delivery of such Units over a 21 year period has contributed to a greater understanding of various plastics pipes materials,...

The behaviour of UPVC pipes exposed to natural weathering for periods up to 51 months has been evaluated in terms of colour change, surface behaviour and low speed mechanical properties and the influence of CaCO,/Tj;0, substitution and gelation variations has been investigated within the programme. As part of a...
