Material of plastic ribbon
1. The plastic ribbon is made of polypropylene material.
2. PP plastic raw material, chemical name: polypropylene, features: low density, strength, stiffness, hardness and heat resistance are better than low pressure polyethylene, can be used at about 100 degrees. It has good electrical properties and high-frequency insulation and is not affected by humidity, but becomes brittle at low temperature, not wear-resistant, and easy to age. Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts.
3. Polypropylene, English name: Polypropylene (PP), molecular formula: (C3H6)n. CAS
Accession number: 9003-07-0, it is a thermoplastic resin obtained by the polymerization of propylene. According to the arrangement of methyl groups, it is divided into isotactic polypropylene (isotactic polypropylene)
polypropylene), random polypropylene (atactic
