Answer:
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient.
The two key categories of plastic are thermoplastics and thermosetting plastics
Pigments are insoluble organic or inorganic particles added to the polymer base to give a specific color to the plastic. Pigments that are organic in nature are hard to disperse and tend to form agglomerates (clumps of pigment particles). These agglomerates can cause spots and specks in the final product.
Plastics are generally low cost, easy to manufacture, durable, strong for their weight, electrically and thermally insulative, and resistant to shock, corrosion, chemicals, and water.
