Plastic Injection Moulding Materials

Key Materials in Plastic Injection Moulding

Plastic injection moulding materials are varied and extensive. Picking the right one is crucial to the overall success of the manufacturing process.

There are a range of plastic injection moulding materials which can be used in the injection moulding process. Each of these plastics has different properties and characteristics. The key is to pick the right plastic for the job. 

This is easier said than done, especially if you have little or no experience of plastic injection moulding. To a newcomer to the industry, the wealth of different plastic types can be overwhelming. 

Choosing the right injection moulding material depends upon several factors, including knowing your application requirements, which can sometimes change between prototyping and production. 

Choosing the Right Grade of Plastic Material

That’s where we can help. At RP, we have plastic injection moulding specialists who have worked in the industry for many years, helping to produce some of the most complex components on the market. Their specialist knowledge of process and material enables them to offer best-fit solution and advice on a range of different projects. 

We are experts in a wide variety of sectors, including automotive, medical, aerospace and electronics. Our production engineers have moulded parts of all shapes and sizes, using a range of different materials.

Our plastic injection moulding managers and technicians are available to all customers, new and old. They are always happy to give advice on which material will be most suited to any given project.

For more information on the main types of plastic injection moulding materials, read our our article, ‘Plastics Under the Microscope,’ where we explore some of the more commonly used plastics in the injection moulding process.

Plastic Injection Moulding Materials

RP Technologies provides low-medium volume plastic injection moulded components in any production intent polymer to support prototype, pre-production, and production volumes. 

We process a wide range of materials, including PEEK, ABS, PC, PC/ABS, PET-G, ASA, SAN, PA6, PA66, PPA, PA12, TPE, TPU and many more.

The table below includes some example grades of plastic material types that we can process for injection moulding purposes, along with links to the relevant data sheets.

This list is not exhaustive – there are many other grades of plastic material available. If you’re looking for a specific plastic polymer which isn’t listed, please contact us to discuss your specific requirements. You can either email us at, or call us on +44 0121 550 5868.
