1. What Is the Common Name of Plastic?
The word "plastic" comes from its plasticity, meaning the ability to be shaped. In the industry, plastic is a general name for a class of materials made from synthetic resins that are moldable and durable.
In daily use and manufacturing, plastics are also informally referred to by their appearance or use:
- White plastic often refers to PE (Polyethylene) or PP (Polypropylene);
- Clear plastic is usually PET (Polyethylene Terephthalate);
- Hard plastic might refer to PS (Polystyrene) or ABS.
- Engineering plastic includes materials like PC (Polycarbonate) and PA (Nylon).
