Material Recommendations for Injection Moulding

Abstract

A hard, rigid material which in its natural form has a high gloss, sparkle and transparency. A wide range of colours is readily available and as the mouldings can also be decorated by a large number of techniques, attractive components can be easily produced. Low water absorption and good electrical insulation properties are other desirable characteristics. However, the polymer is brittle, burns easily and has poor outdoor weathering properties. It is easy to process by injection moulding but this apparent ease can be deceptive as unless care is taken parts that stress-crack in service may result. The density is about 1·05 gcm^-3.
