What Plastic Is Used in Injection Molding?

1. Polyethylene (PE): Lightweight and Durable
Polyethylene is one of the most common plastics used in injection molding. It comes in two main types: high-density polyethylene (HDPE) and low-density polyethylene (LDPE). HDPE is known for its strength and durability, making it ideal for products like containers, pipes, and plastic bottles.

2. Polypropylene (PP): High Flexibility and Chemical Resistance
Polypropylene is another widely-used plastic in injection molding. It is known for its flexibility and high resistance to chemicals. Manufacturers use polypropylene for products such as packaging, automotive parts, and household goods.

3. Acrylonitrile Butadiene Styrene (ABS): Strong and Impact-Resistant
ABS is a strong, impact-resistant plastic commonly used in injection molding. Its strength makes it perfect for products like toys, automotive parts, and electronic housings. ABS is also known for its toughness and ability to withstand heavy use.

4. Polycarbonate (PC): Tough and Transparent
Polycarbonate is a transparent plastic that combines toughness with clarity. It is commonly used in products that require high impact resistance and transparency, such as eyewear lenses, compact discs, and medical devices.

5. Polystyrene (PS): Affordable and Versatile
Polystyrene is an affordable plastic used in injection molding, especially for disposable products. It comes in two forms: general-purpose polystyrene (GPPS) and high-impact polystyrene (HIPS).

6. Nylon (Polyamide): Strong and Wear-Resistant
Nylon is a strong, wear-resistant plastic often used in injection molding for mechanical parts. Products like gears, bearings, and bushings benefit from nylon's durability and low friction. Nylon is also resistant to chemicals, heat, and impact, making it a versatile choice for a wide range of applications.
