Standard, Engineering and High Performance Polymers

We have an in-depth knowledge of polymers, so we know the right types of materials you will need to make your product. We find the most cost-effective and quality solution so you can leave the work to us.

The science of polymers

There is a lot to consider when choosing the right plastic resin for a part; it’s basically a science! With over 85 thousand types of injection moulding plastic materials to choose from, we can only imagine how overwhelming it can be for product designers, engineers, and entrepreneurs alike to get their material selection correct and can sometimes seem like a minefield task.

Material can influence production lead times, cycle times, finished part quality and cost, among other things so narrowing down that extensive list of materials is a critical task right from the very start of your project. By choosing the right material, you can improve the form, fit and function of your parts.
In this article, we look at the basic characteristics of polymers with some examples of popular resins, their applications, and any considerations to make when choosing your material.

At WSM we have an expert materials team on hand to help you with your material selection. If you can’t find what you are looking for here, contact us via our project enquiry form and we’ll do our utmost to support you further.

Below are some common materials and their benefits:

Polymer Benefits
HDPE - Polyethylene (high-density) Easily forms into lightweight containers
LDPE - Polyethylene (low-density) Stretches into fine, tough, films
PET - Polyethylene terephalate Easy to mould, chemical resistant, lightweight, strong
PP - Polypropylene

Lightweight, flexible, doesn't absorb water, doesn't mould in presence of bacteria.

PP is wear-resistant, flexible and can have very high elongation. It’s also resistant to acids and bases.

POM - Acetal High stiffness, low friction, resistant to impact
PMMA - Acrylic Durability, lightweight, smooth surface, easy to clean, affordable
Nylon (Polyamides) Tough with thermal and chemical resistance
PS - Polystyrene Resistant to moisture, lightweight, provides insulation, clean
PVC - Polyvinyl chloride Versatile - cuts, shapes, welds and joins in a variety of styles. Good insulation, lightweight
