About products and suppliers:

Polymer comes in various forms, for instance, polyurethane isocyanate, and can be used to produce a huge array of plastic products. it is a versatile and highly durable material. HDPE, or high density polyethylene, for example, is commonly used in the production of items such as toys, bins, cereal box lining and shampoo and shower gel bottles. TPE - also known as thermoplastic elastomer - tends to be used in the production of glues and adhesives, shoes and household goods. PVC or vinyl polymer is a high strength thermoplastic substance that is often used in the production of medical devices and in wire or cable insulation for construction.
