v PVC
Scientific name: Polyvinyl chloride polymer, density: 1.38-1.43 g / cm3
Physical properties: Young's modulus of elasticity (E) 2900-3400 MPa Tensile strength (σt) 50-80 MPa Elongation @ break 20-40% Notch test 2-5 kJ/m2 Glass transition temperature 87°C Melting point 212°C Vicat B1 85°C Thermal conductivity (λ) 0.16 W/mK Thermal expansion coefficient (α) 8 10-5 /K Heat capacity (c) 0.9 kJ/(kg·K) Water absorption (ASTM) 0.04-0.4.
Main products: floor, ceiling and leather surface, water pipes, etc.
Main application areas: wire and cable, various membranes, flooring materials, fabric coatings, artificial leather, various hoses, gloves, toys, plastic shoes and special coatings. Doors and windows, various profiles, pipes, sheets, etc.
v PP
Scientific name: Polypropylene density: 0.9-0.91 g/cm3
Physical properties: molding shrinkage: 1.0-2.5% molding temperature: 160-220 ° C melting temperature: 220 ~ 275 ° C
Drying conditions: material properties, 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 is not affected by humidity, but becomes brittle at low temperature. Not wearable and easy to age.
Main products: basins, barrels, furniture, film, woven bags, bottle caps, car bumpers, etc.
Application areas: wire drawing products, injection molding products, automotive industry
v PS
Scientific name: Polystyrene density: 1.05 g / cm 3
Physical properties: Molding shrinkage: 0.6-0.8% Molding temperature: 170-250 ° C, excellent electrical insulation (especially high-frequency insulation), colorless and transparent, light transmittance is second only to plexiglass, coloring water resistance, chemistry Good stability, general strength, but brittle, easy to produce stress cracking, not resistant to organic solvents such as benzene.
Main products: fast food box, TV case, refrigerator decoration parts, audio and video products box, software box, communication equipment, camera equipment, kitchen utensils, audio capacitors, toothbrush handles, combs, ballpoint pens, etc.
Application areas: foam products, injection molding products
v ABS
Scientific name: Acryloitile Butadiene Styrene Density: 1.05 g / cm 3
Physical properties: It is a resin with high strength, good toughness and excellent comprehensive performance. The bending strength and compressive strength of ABS are poor, and the mechanical properties are greatly affected by temperature. Thermal performance: HDT: 93-118 ° C, can be used in the range of 40 ° C -100 ° C. , electrical properties: good insulation, not affected by temperature, humidity and frequency. It is not affected by water, inorganic salts, alkalis and various acids. It is excellent in impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It is also easy to process, product dimensional stability and surface gloss. Good characteristics, easy to paint, color, can also be surface metallization, plating, welding, hot pressing and bonding secondary processing.
Main products: car dashboard, ABS pipe, ABS sanitary ware, ABS decorative board
Application areas: automotive, electronic appliances, building materials, etc.
