Semi-Crystalline – CP
Commodity Plastics (Semi-Crystalline)
PET – Polyethylene Terephthalate – a strong, stiff synthetic fibre and resin, and a member of the polyester family of polymers. PET is spun into fibres for permanent-press fabrics, blow-molded into disposable beverage bottles, and extruded into a range of applications including film and sheet for thermoforming.
PP – Polypropylene – A synthetic resin built up by the polymerization of propylene. Three types of PP are available covering: Homopolymers, Block copolymers and Random Copolymers. polypropylene is molded or extruded into many plastic products in which toughness, flexibility, light weight, and heat resistance are required. It is also spun into fibres for employment in industrial and household textiles.
PE – Polyethylene – PE is a versatile synthetic resin made from the polymerization of ethylene. Polyethylene is classified into several different categories based mostly on its density and branching. The most important polyethylene grades are HDPE, LLDPE and LDPE. PE is the most widely used polymer with wide ranging applications covering bags, food packaging, and industrial piping applications.
