Below you'll find links to short descriptions of the most commonly used plastic materials for injection moulding.
In their natural form amorphous materials are generally transparent with a fairly good rigidity, but normally poor thermal properties. There are however amorphous materials with extremely good thermal properties, but the price of these materials is relatively high.
Semi crystalline materials are opaque and characterized by great strength, a higher use temperature and in some cases extremely good bearing properties (low friction and high wear resistance).
In addition to the materials mentioned above there is a large group of “composite materials”, that is materials containing e.g. fibres such as glass fibres, kevlar fibres, carbon fibres etc. as well as other additives in order to give the materials special properties. ABS - Acrylonitril-Butadiene-Styrene PS (SB, MIPS, HIPS) - Polystyrene PE (LDPE,LLDPE,HDPE) - Polyethylene PP - Polypropylene PA - Polyamide (Nylon) POM - Polyoxymethylene (Polyacetal) PC - Polycarbonate (Lexan) PVC – Polyvinylchloride TPE - Thermoplastic elastomers PUR - Polyurethane
