There are several types of plastics that are used when making mouldings. Some plastics are used for certain products while other plastics are used for other types of products. Here are some of the more common types of plastics used in UK moulding procedures and what some of them are used for.
HDPE
This type of plastic, which has the technical name of High Density Polyethylene, has many uses. It offers a great moisture barrier which makes it ideal for a variety of applications in the household and beyond. You’ll find HDPE plastics when you buy products like cereals, snack items, rice and other things that cannot be exposed to moisture. If these products are exposed to moisture, it can ruin them. HDPE is also used for containers like butter tubs, beverages and deli foods, among others. Because it is also resistant to chemicals, it’s ideal for other types of packaging as well, such as household cleaners, acids and detergents.
PVC
PVC, or Polyvinyl Chloride, is another popular plastic used in UK moulding projects. One of the benefits of using PVC is that it is transparent, making it ideal for products such as plastic milk jugs and juice containers. PVC plastics range from the flexible to the rigid, making it one of the more versatile options to choose. PVC is often used in piping through homes because it is resistant to chemicals and it is less vulnerable to micro-organisms and bacteria. You also don’t have to be concerned about corrosion when using PVC pipes and pipe fittings in your home. Other uses for PVC materials include insulation, floor coverings, medical tubing and more.
LPDE
Low Density Polyethylene is often used for plastic moulding because of its toughness and flexibility. It has a low melting temperature which makes it ideal for projects when heat sealing is important. Some of the products that use LPDE include flexible items such as plastic grocery bags and garment bags often used by dry cleaners. But it’s also used for manufacturing lids and bottles. Because LPDE also has stable electrical properties, it is often used with cables and wires to add extra insulation and safety.
PS
PS, or Polystyrene, is one of the more versatile plastics used in moulding. It can be foamed or rigid and its main benefit is its transparency. That makes products made from PS ideal for situations involving laboratories, food packaging and medical procedures.
