Polypropylene (PP) also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance
PPCP or polypropylene copolymer is a thermoplastic polymer material. it is one of the two forms of pp available other being the Homopolymer. this form is a bit softer but has a high impact strength. moreover, it is more tough and durable than the Homopolymer. in addition, it has a high crack resistance and low-temperature toughness as well. more importantly, this copolymer does not absorb moisture. it is both chemical and corrosion resistant. the applications of this copolymer include the production of die cutting pads, fire truck water tanks, anodizing equipment, fabricated parts, etc. apart from that, this copolymer is versatile and inexpensive.
The Homopolymer is the widely used form of PP. it has a high strength as compared to the weight. moreover, it is stiffer and stronger than copolymer. it is useful in many corrosion resistant structures because of the high chemical resistance and weldability. PP has applications in clothing, medicine and niche. it is useful in producing nonwoven clothes. this polymer is recyclable.
Polypropylene random copolymers are thermoplastic resins produced through the polymerization of propylene, with ethylene or butene bonds introduced in the polymer chain. The resins provide a broad range of characteristics, and are used in a wide range of applications.
