Thermoforming is a manufacturing process used to shape plastic sheets into specific forms. Various plastic raw materials can be used for thermoforming, depending on the desired characteristics and applications. The most common types of plastic used for thermoforming include:
- Polyethylene (PE): This is a widely used plastic for thermoforming due to its versatility and cost-effectiveness. It is available in different forms such as high-density polyethylene (HDPE) and low-density polyethylene (LDPE), each with its own set of properties.
- Polypropylene (PP): PP is another popular choice for thermoforming due to its excellent chemical resistance and high-temperature stability. It is commonly used for packaging, automotive components, and consumer products.
- Polystyrene (PS): PS is a rigid and lightweight plastic that is frequently used for thermoforming applications. It is available in different forms, including general-purpose polystyrene (GPPS) and high-impact polystyrene (HIPS), which offers improved impact resistance.
- Polyvinyl Chloride (PVC): PVC is a versatile plastic used in various industries. It can be rigid or flexible, depending on the formulation, and is commonly used for packaging, signage, and construction materials.
- Acrylonitrile Butadiene Styrene (ABS): ABS is a durable and impact-resistant plastic that finds applications in automotive parts, electronic enclosures, and consumer products. It is known for its excellent surface finish and dimensional stability.
- Polycarbonate (PC): PC is a strong and transparent plastic with high impact resistance. It is commonly used for products that require optical clarity, such as safety goggles, automotive headlights, and electronic display screens.
These are just a few examples of the plastic raw materials used for thermoforming. The selection of a specific material depends on factors such as desired properties, cost, regulatory requirements, and the intended application of the formed plastic product.
