Polypropylene (PP), also known as polypropylene, is a thermoplastic polymer, which is widely used in various fields. It is an addition polymer formed by chain extension polymerization of monomer propylene. Polypropylene can be produced in various structures, leading to various applications, including packaging and labels, textiles, plastic parts and various types of reusable containers, laboratory equipment, automobile parts and medical equipment. This is a white material with high mechanical strength, which is resistant to many chemical solvents, alkalis and acids.
Among general plastics, PP has the best heat resistance, its thermal deformation temperature is 80- 100℃, and it can be boiled in boiling water. PP has good stress cracking resistance and long bending fatigue life, commonly known as "hundred-fold adhesive". The comprehensive performance of PP is better than that of PE. PP products are light in weight, good in toughness and chemical resistance.
