All plastics are synthetic resins or commonly known as synthetic resins and these are classified into the following two categories.
1- Thermoplastic Resins: These type of resins can be re-softened by heating them at different temperatures. PS, PE, PP, and PVC are examples of thermoplastic resins.
2- Thermosetting Resins: Resins of this type are already hardened by using high temperatures and will never change their property to become soft again. Melamine and Phenolic resins are examples of thermosetting resins.
Classification of Plastics
PET or PETE: Is also known a PETE or polyethylene terephthalate. It is a resin from thermoplastic polymer family and widely used in a polyester fiber, food containers, food trays, and beverage drinks bottles. Melting point: 500°F 260 °C
HDPE: Is a thermoplastic polyethylene, It is also known as high-density polyethylene and has a high strength to density ratio. Its resistance to many solvents makes this a choice of plastic for Chemical resistant pipes, Fuel tanks, water pipes, bottles and blow mold plastic applications. Melting Point: 266°F 130°C
PVC or V: Is also known as Vinyl or polyvinyl chloride in some parts of the world. It has a high fire resistance due to the presence of chlorine. PVC is broadly used in insulation of wires, flooring, artificial leather, windows, and pipes. Melting point: 176°F 80°C
PP: Is from a thermoplastic resin family also know as polypropylene and used in various application such as labeling, textile, reusable containers, carpets, lab equipment, and stationery. Melting point: 266°F 130°C
PS: Also known as polystyrene. It can be foamed or solid. A common example of foamed PS is white brittle packing material or sheets. Other use of PS is disposable cutlery, yogurt tubs, cd/dvd cases bottles lids and trays. Melting point: 464°F 240°C
