What are the commonly used plastics?

Commonly used plastics are: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile butadiene styrene (ABS).

1. polyethylene

Polyethylene plastic is soft and feels like wax. Compared with the same plastic, it has light weight, certain transparency and blue flame when burning. The main applications are: plastic wrap, vest plastic bag, plastic food bag, milk bottle, pail, kettle and so on.

2. Polypropylene

Polypropylene is a thermoplastic resin polymerized from propylene. It is mainly used for injection-molded parts of household appliances, modified raw materials, daily injection-molded products, pipes and so on.

3. PVC

PVC used to be the largest general-purpose plastic in the world, and it was widely used. Widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers and so on.

4. polystyrene

Polystyrene plastics are widely used in optical instruments, chemical departments and daily necessities, and are used to make tea trays, sugar cans, soap boxes, cigarette cases, student rulers, combs and so on. Because of its certain air permeability, it can be used as a good food packaging material when made into film products.

5. Anti-lock braking device

Plastic ABS has good electrical insulation and is almost unaffected by temperature, humidity and frequency, so it can be used in most environments. The biggest application fields of ABS resin are automobiles, electronic appliances and building materials.
