The injection molding industry has developed rapidly over the last few decades and is now one of the most important technologies in modern manufacturing. In this article, we would like to give you an insight into the different plastics used in injection molding to meet the diverse needs of different industries.
Polypropylene (PP): This plastic is lightweight, has a high melting point and good chemical resistance. It is commonly used for packaging, food containers, toys and automotive parts.
Polyethylene (PE): There are different types of polyethylene, including high density polyethylene (HDPE) and low density polyethylene (LDPE). Resistant to moisture, chemicals and UV radiation, polyethylene is used for packaging, bottles, pipes and containers.
Polyvinyl chloride (PVC): PVC is a versatile plastic with good chemical, fire and water resistance. It is used for pipes, window frames, electrical insulation and medical equipment.
Polystyrene (PS): Polystyrene is light, rigid and transparent. It is used for packaging, food containers, disposable tableware and electronic housings.
Polycarbonate (PC): Polycarbonate is a durable plastic with high impact strength that is also resistant to UV radiation and high temperatures. Typical applications are eyeglass lenses, vehicle parts and protective equipment.
Polyamide (PA), also known as Nylon: Nylon has high tensile strength, wear resistance and chemical resistance. It is used for mechanical parts, gears, textile fibers and sports equipment.
Acrylonitrile Butadiene Styrene (ABS): ABS is an impact resistant material used in many industries. It is used for casings of electronics, toys, automobile parts and household items.
Polymethyl methacrylate (PMMA), also known as acrylic glass or Plexiglas: PMMA is a transparent plastic with high light transmission and weather resistance. It is used for windows, neon signs, medical devices and optics.
Polybutylene terephthalate (PBT): PBT is an engineering plastic with high rigidity, chemical resistance and thermal stability. It is used for electrical and electronic components, automobile parts and precision mechanics.
Polyoxymethylene (POM), also known as Acetal or Delrin: POM is an engineering plastic with high strength, stiffness and wear resistance. It is used for gears, bearings, clips and other mechanical parts.
This list is not exhaustive, but includes some of the most commonly used plastics in injection molding.
