Polypropylene (PP) is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, resistance to various organic solvents and acid-base corrosion. It has a wide range of applications in the industry and is one of the most commonly seen polymer materials.
Mainly used in the production of various long and short polypropylene fibers, used in the production of polypropylene woven bags, packaging bags, injection molded
products, etc. for the production of electrical, telecommunications, lighting, lighting equipment and TV sets of flame retardant parts.
