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).

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.
