What is Plastic?

Plastic is a material consists synthetic or semi-synthetic organic compounds, which can be molded into different kinds of products by Plastic Injection Molding/ Plastic Injection Mould Machine.

Synthetic resin is the most important component of plastics, and it's proportion up to 40-100%. Because of synthetic resin's high proportion, usually the property of syntheric resin determine the property and nature of plasstic. That's why resin is often considered as plastic.

Plastic's classifications:

1. chainsthe acrylics, polyesters, silicones, polyurethanes, and halogenated plastics.(they are classified by: the chemical structure of the polymer's backbone and side)

2. condensation, polyaddition, and cross-linking, which are classified by the chemical process used in their synthesis

3. organic solvents, oxidation, and ionizing radiation, which is classified by their various physical properties, such as: hardness, density, tensile strength, resistance to heat and glass transition temperature, and by their chemical properties, such as the organic chemistry of the polymer and its resistance and reaction to various chemical products and processes.
