In part 1 of ‘Your Guide to Plastics for Custom Injection Moulding’ we looked at the qualities and uses of the 5 most popular types of plastic resin used for custom moulding. Acrylic, Acrylonitrile butadiene styrene, Nylon, Polycarbonate and Polyoxymethylene make up some of the most popular plastics in use for injection moulding. In this blog, we look at the other 5 key injection moulding plastics that sit within the ten most popular resins for custom moulding.
Of course, if you need any further advice or information about any of our products or services, you can contact our customer services team through the chat feature on our website.
Polyethylene – the most commonly used plastic in the world comes in different densities: high-density polyethylene (HDPE) and low-density polyethylene (LDPE) and each has different properties when it comes to hardness, flexibility, melting point and even optical transparency. HDPE is more opaque than LDPE but LDPE is softer and more flexible than LDPE.
Properties of PE:
Uses of PE:
Polypropylene is the most common plastic in the world. Its popularity is largely due to its robust chemical resistance and ability to retain its shape even under duress or upon torsion
Properties of PP:
Uses of PP:
Lightweight, comparatively inexpensive and resistant to moisture and bacterial growth, there are two types of polystyrene: General Purpose Polystyrene (GPPS) and High Impact Polystyrene (HIPS).
GPPS is more brittle than HIPS and has a glass-like transparency whereas HIPS is opaque.
Properties of PS:
Uses of PS:
Thermoplastic Elastomer is processed like plastic but offers the properties of rubber. Sometimes referred to as thermoplastic rubber, TPE can be stretched to moderate elongations and still return to its original shape. TPE can also be recycled infinitely.
Properties of TPE:
Uses of TPE:
Thermoplastic Polyurethane has a rubber-like elasticity and good load-bearing capabilities. It can withstand exposure to ozone too, with a superior resistance to extreme temperatures and chemicals.
Properties of TPU:
Uses of TPU:
When we first established Banbury Plastic Fittings Ltd we planned to use the latest injection moulds to create unique and innovative component solutions in plastic through custom moulding for our clients.
Our tools are run on the latest automated injection moulding machines for greater precision and faster, more cost-effective product runs, and we ensure speedier turnaround than many of our competitors by running our machines 24 hours a day.
And, because we run a customer-centric business, we specify all types of thermoplastics ranging from sophisticated engineering polymers to basic commodity polymers in a wide range of colours so we can deliver the right type of fittings to meet your needs so you can be confident in your products.
For specific questions about any of our custom plastic mouldings or simply to find out how we can help you with our custom injection moulding contact our advisors on our online chat.
