Common raw materials for injection molding include the following:
Polypropylene (PP): Polypropylene is a hard and heat-resistant plastic with good chemical resistance and recyclability. It is often used to make disinfection, commercial and industrial products, such as fenders, vents, etc. in the automotive industry.
Polyethylene (PE): Polyethylene is a common plastic that is divided into high-density polyethylene (HDPE) and low-density polyethylene (LDPE) according to density. It has good chemical resistance and low cost and is often used in packaging and household goods.
Polystyrene (PS): Polystyrene is a colorless and transparent plastic with good optical and electrical properties, but poor heat resistance. It is often used in product packaging, household goods and electrical components.
Acrylic (PMMA): Acrylic is a strong and transparent thermoplastic with high tensile strength and light resistance, and is often used in construction and lighting applications.
Acrylonitrile Butadiene Styrene (ABS): ABS is an engineering-grade thermoplastic known for its strength and impact resistance, and is widely used in electronic components, automotive accessories, etc.
Nylon (PA): Nylon is an engineering plastic with high mechanical strength and wear resistance, and is often used to manufacture mechanical parts and bearings.
Polycarbonate (PC): Polycarbonate is a strong, transparent plastic with high durability and chemical resistance, and is often used in mechanical guards and LED lamps.
Polyoxymethylene (POM): Polyoxymethylene is an engineering plastic with high stiffness and wear resistance, and is often used to manufacture precision parts and bearings.
Thermoplastic Elastomer (TPE) and Thermoplastic Polyurethane (TPU): These materials have rubber-like elasticity and are suitable for footwear, medical devices, and electronic devices.
Selecting the right injection molding material requires considering factors such as application requirements, physical properties, chemical stability, processing performance, cost, and sustainability. Each material has its own unique advantages and disadvantages and is suitable for different application scenarios.
