"</p><p><br></p><p><strong>&nbsp;1. Definition</strong></p><p>Polypropylene is a thermoplastic resin obtained by the polymerization of propylene, which is non-toxic and tasteless. Its molecular structure is a typical regular structure of the main body, a crystalline polymer, and its molecular weight is 100,000 to 500,000. Specific gravity: 0.9-0.91 g / cm3, molding shrinkage: 1.0-2.5% molding temperature: 160-220 ℃ According to the arrangement of methyl groups, it is divided into three types: isotactic polypropylene, random polypropylene and syndiotactic polypropylene. It has the advantages of high strength, high hardness, wear resistance, bending fatigue resistance, high heat resistance temperature, excellent moisture resistance and chemical resistance, easy processing and molding, and low price. At the same time, it has the disadvantages of poor low temperature toughness and aging resistance.</p><p><br></p><p><strong>2. Features</strong></p><p>&nbsp;1.
