PP plastic , chemical name: polypropylene
English name: Polypropylene (referred to as PP)
Specific gravity: 0.9-0.91 g / cm3 Shrinkage: 1.0-2.5% Molding temperature: 160-220 ° C
PP is a crystalline polymer, commonly used in plastic PP lightest, the density is only 0.91g / cm3 (smaller than water.) General plastic, PP heat resistance is the best, the heat distortion temperature of 80-100 ℃, Can be boiled in boiling water.PP has a good resistance to stress cracking, a high bending fatigue life, commonly known as "Bai Bai glue". PP comprehensive performance is better than PE material. PP product quality light, good toughness, Good chemical .PP shortcomings: the size of low precision, lack of rigidity, poor weather resistance, easy to produce "copper harm & rdquo ;, it has a post-shrinkage phenomenon, after stripping, easy aging, brittle, easy to deformation.
Anti-UV PP, PP1, anti-UV polypropylene with a transparent, anti-ultraviolet, good toughness, high impact, good lubricity, excellent resistance to light aging and thermal aging performance And other advantages, in order to ensure the safety of the car in harsh environments, according to customer requirements for the product by the professional and technical engineers tailored to the most suitable for the quality of engineering plastics products.
Uses: used in automotive parts, interior parts, endoscopes, door handles, refrigerators, washing machines, thin-walled containers, battery boxes, tool boxes, plates, baskets, small containers, household goods, small commodities, toys and many other areas.
