Some important polymers
The eight most common types of synthetic organic polymers, which are commonly found in households are:
Low-density polyethylene (LDPE)
High-density polyethylene (HDPE)
Polypropylene (PP)
Polyvinyl chloride (pvc)
Polystyrene (PS)
Nylon, nylon 6, nylon 6,6.
Teflon (Polytetrafluoroethylene)
Thermoplastic polyurethanes (TPU)
Some Important Polymers
⇒ Polythene : It is chemically inactive and water resistant, tough, flexible and strong and can be moulded in desired shape.
⇒ Polyvinyl chloride (PVC) : It is more tough than polythene.
⇒ Polystyrene : It is very light and can be easily blown and easily mouldable than polythene.
⇒ Perspex : It is extremely tough , light and very transparent and has high optical clarity.
⇒ Teflon : It is very tough material and is resistance towards action of acids and bases. It is a bad conductor of heat.
⇒ Rayon : It is synthetic fiber that is man-made fiber prepared from natural raw materials called cellulose. It has silky look and is similar to cotton.
⇒Nylon : It is a group of polymers containing amide groups, hence, it is a polyamide. It is chemically inert, heat resistance, tough and very strong.
⇒ Polyesters : These fiber contain ester group. They do not get wrinkled easily but remained crisp, so are easy to wash.
⇒ Melamine : It is a versatile material, resistance to fires and can tolerate heat better than other plastics. It is used for floor tiles, kitchenware, and fabrics that resist fires.
