There are several types of plastic raw materials, each with their own unique properties and characteristics. Here are some common types:

Polyethylene (PE): This is the most commonly used plastic material, which is known for its durability, flexibility, and resistance to moisture.

Polypropylene (PP): This type of plastic is used in a variety of applications including packaging, textiles, and automotive parts. It has high tensile strength, is resistant to heat and chemicals, and has a low density.

Polyvinyl chloride (PVC): PVC is a highly versatile plastic that can be used in a variety of applications such as pipes, electrical insulation, and flooring. It is known for its durability, toughness and resistance to chemicals.

Polystyrene (PS): This is a lightweight plastic used in many different applications such as disposable cups, food containers, and insulation. It is also used in toys and other consumer products due to its ease of processing.

Acrylonitrile butadiene styrene (ABS): ABS is a strong, rigid plastic that is often used in automotive parts, toys, and electronics. It is known for its toughness and resistance to impact.

Polyethylene terephthalate (PET): PET is commonly used in the production of bottles and other food packaging due to its clarity, resistance to impact and gas permeability.

These are just a few examples of the many types of plastic raw materials available. Each type of plastic has its own unique characteristics, making it suitable for different applications.
