When it comes to plastic injection moulding, there are many different types of materials to choose from. This guide will review several different types of plastics that can be used in the injection moulding process.
Polyvinyl chloride is a very popular option for plastic injection mouldings. This plastic is better known as PVC, and it’s a common choice because it is durable and resistant to chemicals, flames, and abrasion.
The tensile strength of PVC is about 6,500 PSI, and it provides solid dimensional stability and dielectric properties. This stability makes PVC perfect for the injection moulding process, and since the durometers range from rigid to soft and flexible, there are many applications.
Polyvinyl chloride is often used to make pipe fittings and similar parts.
Another material used for plastic injection mouldings is polypropylene. This plastic is unique because it does not allow chemicals to mix with food products – making it a great choice for things like bottle caps and lids for food storage containers.
Polypropylene can also withstand being washed in high temperatures while maintaining its toughness, elasticity, and impact strength. As a result, it’s a favourite for companies in the packing or food industry.
Acrylonitrile Butadiene Styrene
ABS, which stands for acrylonitrile butadiene styrene, is an engineering grade plastic. It creates an opaque thermoplastic polymer that is tough, impact and scratch-resistant, and has good dimensional stability.
This option is very affordable and has a low melting temperature making it perfect for the plastic injection moulding process. This product is a great choice for products like keyboards and electronic parts.
High-density polyethylene, or HDPE, is a very lightweight material. This plastic is very flexible, and its properties prevent it from absorbing water. It’s not especially hard or strong but it’s high chemical resistance, electrical insulating properties, and elasticity allows it to be utilised for common consumer plastic parts.
HDPE is one of the most common plastics used to create children’s toys and items like milk and detergent bottles. It’s used to manufacture garbage bins and plastic bags and can have several medical applications as well.
Styrene Acrylonitrile Resin
Styrene acrylonitrile resin is just like ABS, only it does not have the butadiene component. This means that it has a lower impact strength, but the main benefit is that the products you create can be crystal clear!
This plastic injection moulding material is more resistant to chemicals than polystyrene, and it is also more affordable than other acrylics. Simply put, it has a solid balance of toughness, transparency, rigidity, and strength.
Some applications for this type of plastic include lenses, switches, trays, battery cases, and medical light diffusers.
