plastic moulding material selection guide

To help you select the right plastic for your mouldings, this plastic moulding material selection guide lists the most common plastic material types available together with an overview of basic properties of each plastic when in natural colour unfilled grade. This guide also lists typical trade names, costs & uses for mouldings made from each type of plastic material.

 

Toolcraft have worked with a very wide range of plastic materials over the years and are able to help you select the right material for your moulding project. We have some very knowledgeable suppliers as well.
