H670 fiber grade PP LG Chemical Uses: Fiber Important parameters: melt flow rate: 35 g / 10min density: 0.903 g / cm3 mold shrinkage: 1.7% notched impact strength: Tensile strength: 36.26 MPa Elongation at break: 500 % Hardness: 104 Vicat softening point: 152 ℃ heat distortion temperature: 123 ℃ Manufacturer: South Korea's LG Chemical Company PP polypropylene comprehensive overview: PP plastic, chemical name: Polypropylene English name: Polypropylene (referred to as PP) weight: 0.9 0.91 grams / cubic centimeter molding shrinkage: 1.0-2.5% molding temperature: 160-220 ℃. Heat distortion temperature of 80-100 ℃, a high flexural fatigue resistance, commonly known as "pleated plastic." PP has good electrical properties and high-frequency insulation (from humidity temperature), but the low temperature brittle, do not wear, easy to aging, not easy to aging. Suitable for production of general machinery parts, corrosion-resistant parts and insulating parts. PP polypropylene Application Usage: 1, film products: PP film products transparent and shiny, water vapor and air permeability is small, it is divided into blown film, cast film (CPP), biaxially oriented film (BOPP) and so on. 2, injection molding products: used in automotive, electrical, mechanical, instrumentation, radio, textile, defense and other engineering accessories, daily necessities, turnover box, medical equipment, building materials. 3, extrusion products: do tubes, profiles, monofilament, fishing rope, packing tape, tied belay, woven, fiber, composite coating, sheet, plate, etc., blow molding products various small containers . 4, Other: low foaming, calcium plastic board, synthetic wood, laminate, synthetic paper, high foaming can be used for structural foam. PP injection molded polypropylene resin products in the proportion of injection molded article can be accounted for about half, including daily necessities of ordinary PP as raw materials, auto parts to enhance or toughening PP as raw material, while the other uses either high impact strength and low brittle temperature The copolymer polypropylene PPC-based raw materials. Cars: PP auto parts increasingly become the dominant material, becoming the first major automotive plastic varieties. Toughening PP bumper and wheel housing enclosures, reinforced PP is used for the dashboard, steering wheel, handle, container, battery shell. Commodity: General PP used in the injection molding hangers, chairs, stools, barrels, pots, toys, stationery, office supplies, furniture, hinges, turnover box. Appliances: modified PP bucket for washing machines, TV cabinet, Fan Ye, refrigerator liners, small appliances, such as Shell. Features polypropylene non-toxic, tasteless, density, strength, stiffness, hardness and heat resistance are superior to low-pressure polyethylene, can be used at 100 degrees. Has good electrical properties and high-frequency insulation from humidity, but the low temperature brittle, do not wear, easy to aging. Suitable for production of general machinery parts, corrosion-resistant parts and insulating parts. Common acid and alkali organic solvents it almost does not work, can be used for utensils. Physical properties of polypropylene properties: PP is non-toxic, odorless, tasteless milky white highly crystalline polymer, forming a good, but the shrinkage, thick-walled products easy to depression, product surface gloss, easy coloring. Mechanical properties: high crystallinity PP, regular structure, which has excellent mechanical properties, their strength and hardness, elasticity than HDPE at room temperature and low temperature, with high regularity in molecular structure itself, so the impact strength than poor, when the increase in molecular weight also increases the impact strength. Thermal Performance: PP has good heat resistance, melting point at 164-170 degrees, the product can be sterilized at a temperature above 100 degrees, without being subject to external forces, 150 degrees is not deformed, brittle transition temperature -35 degrees, -35 degrees below embrittlement occurs, cold but not as good as Polyethylene. Chemical stability: PP good chemical stability, to base its various chemical reagents are relatively stable. Weather resistance: PP UV-sensitive by adding carbon black or similar creamy white fillers such as to improve its anti-aging properties.
