The Introduction of PP 1100NK

PP 1100NK, PP, also known as polypropylene, commonly known pleated plastic; eccentric plastic Thai Petrochemical PP 1100NK provided is a non-side-chain, highly crystalline linear polymer plastic, harder than PE, and the melting point is high, it with excellent performance, the proportion of small, rigid, flex-resistant, high strength, resistance to chemical corrosion, almost non-absorbent, good fluidity, easy to process; and have excellent fiber-forming nature, known as the " ideal fiber, "which is very good tensile properties, the applications is very broad; the automotive industry, intermediate load bearing components of the ideal material for the most economical. PP is generally irregular surface waxy luster white round pellets, density 0.9-0.91g/cm3 is the lightest kind of plastic, have a more obvious melting point, according to the different crystallinity and molecular weight, melting point at 170 ℃ up and down, above the decomposition temperature of 290 ℃, so the PP has a very wide range of molding temperature, molding shrinkage of 1.0-2.5%; and uniformity of shrinkage in the direction other than the PE-HD material is much better; PP does not exist environmental stress cracking problems, usually by adding fiberglass, metal additives or other methods of thermoplastic rubber modified PP, it's better performance; with 30% glass additive can make shrinkage down to 0.7%, respectively, polymer-and copolymer type of PP material with excellent moisture absorption, resistance to acid corrosion, anti-solubility; Vicat softening temperature of PP 150 ℃, as high crystallinity, the material stiffness and resistance of the surface properties of very good marks; for hands and surfaces often easy access to high product demands; PP at room temperature, in fact, completely from water erosion, but in addition to outdoor use outside Canada need to add some antioxidant light stabilizer; PP with temperature up to 100 ℃, has good electrical properties and high-frequency insulation, and the humidity is changed from less than lies, will become brittle at low temperatures, do not wear, easy to aging, suitable for production of general mechanical parts, components and corrosion-resistant insulating layer, in addition, with the PP production will hinge products with outstanding fatigue resistance, in the pharmaceutical, food, chemical industry and daily life of PP has a wide range of uses; PP Application description: Consumer goods: pots, barrels, film, small furniture, bags, caps, lawn garden equipment, such as lawn mowers and sprinklers, etc.; automobile manufacturing industry: the main use of metal additives PP, used production of fenders, bumpers, fan blades, ventilation pipes, etc.; equipment manufacturing: such as dishwasher gaskets, refrigerator door gasket, washer frame and cover, dryer vent pipes, etc.; engineering plastics can be used for: electrical insulation material, anti-corrosion pipe, sheet, TV shell, tank, etc.; Processing of PP are many ways: extrusion, injection molding, pressure molding, blow molding and thermoforming, etc.; PP injection molding screw injection molding machine to the main injection conditions: feed temperature of 200 ~ 250 ℃, mold temperature 40 ~ 60 ℃, injection pressure of 40 ~ 70MPa; molding conditions selected should also consider the shape of the mold shrinkage structure and cooling, the product stripping and other issues; PP 1100NK if not stored properly dried prior to processing, but in the process of cooling must beware of too fast, pouring and cooling system, cooling system should be slow and pay attention to controlling the temperature, the material temperature was low directivity, low temperature high pressure particularly evident in the mold temperature is below 50 ℃, the plastic is not smooth, easy to produce bad welding, there are traces, 90 ℃ or more easy to produce warpage, plastic wall thickness to be uniform to avoid the lack of plastic, sharp corners to prevent stress not naturally eliminated; if the products had surface defects, then you should use a high temperature low injection. National company and agent of plastic raw material, polypropylene PP origin and variety of goods. Is launching a number of origin, various models for reference: Japan Culp: FR150, GF-1510A, Japan Purui Man: J105G, J747W, X810L, J715M, V7104, Thailand Basel: HP480S, RP100, EP300L, RP348N, Thailand petrochemical: 1100NK, 1100PK, 1100RC, 1126NK, 3342R, 2500H, 3240H, 3342M, 348S, SCG Chemicals, Thailand: P840J. Polypropylene (PP) Characteristics: 1. Physical properties: non-toxic, odorless, tasteless white high crystallinity of the polymer. All plastic is one of the lightest species. (2) mechanical properties, 3 thermal performance: PP has good heat resistance. 4 chemical stability, 5 electrical properties, 6. Weatherability. Uses: film products, injection products, squeezing products, other and so on.
