PP (polypropylene) belongs to the semi-crystalline material, it belongs to the polyolefin. The semicrystalline structure casts its physical properties and has a high melting point. Due to its characteristic low density of 0.9, PP is one of the lightest thermoplastics. In addition, PP (polypropylene) is also an ecological and sustainable thermoplastic material, with excellent material and processing properties. Mainly used in pipe extrusion and packaging industry, and furniture industry. PP provides significant chemical properties and sustainability beyond other materials.
