They are strong and waterproof, and can be made into any shape of color. Many plastics can be made transparent. They are not magnetic and do not conduct heat or electricity.

Properties of Plastic

Plastics have numerous properties that make them superior to other materials in many applications. Plastics generally have: resistance to corrosion and chemicals, low electrical and thermal conductivity, high strength-to-weight ratio, colors available in a wide variety and transparent, resistance to shock, good durability, low cost, are easy to manufacture, resistant to water and have low toxicity.

Types of Plastic Materials

Plastic materials include: polypropylene (PP), polystyrene (PS), high impact polystyrene (HIPS), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), polyester (PES), polyamides (PA) (Nylons), poly(vinyl chloride) (PVC), polyurethane (PU), ,polycarbonate (PC) and polyethylene (PE).

The name Plastic is derived from the Greek word plastikos, which means able to be shaped. Plastic materials consist of long chain molecules (polymers). Available in many colors and in transparent form, plastics can be rubbery or rigid. Plastic shapes include sheet, rod, hex, pipe, cubes, balls, tubes, etc.
