ABS Taiwan's Chi Mei PA-765A high flow resistance but high impact ABS injection molding grade level common plastic

ABS production methods: 1. acrylonitrile - styrene copolymer (AS) and polybutadiene (B) mixing, or after mixing these two kinds of latex copolymer; 2. Add acrylonitrile in polybutadiene latex and styrene monomer graft copolymer. ABS resin color is a little yellowish, ABS has a certain toughness, density of about 1.04 ~ 1.06 g / cm3. ABS with acid, alkali, salt corrosion relatively strong, can be tolerated in the organic solvent dissolves to some extent. OI: 18.2% is a flammable polymer. ABS When adjusting the proportions of the three ingredients blended, the physical properties of ABS resin, there will be some changes: butadiene provide low temperature ductility and impact resistance of ABS resin, but too much will reduce butadiene resin hardness, gloss and mobility; acrylonitrile provided as ABS resin properties hardness, heat resistance, acid salt and other chemical corrosion; styrene provides ABS resin hardness, finish machining of liquidity and the product surface. Structure, properties and applications in ABS resin, rubber particles were dispersed, SAN resin dispersed in a continuous phase. When impacted, the crosslinked rubber particles to withstand and absorb this energy, so that the stress dispersion, thereby preventing the development gap, in order to improve anti-tear properties. ABS molding performance: amorphous material, liquid medium, moisture large, must be fully dried, the surface gloss plastic parts requested to be preheated drying time 80-90 degrees, three hours should take high melt temperature, high mold temperature, though. high temperature materials easily decomposed (decomposition temperature> 270 degrees) for high precision plastic parts, mold temperature should take 50-60 degrees, high gloss. Heat plastic parts, mold temperature should take 60-80 degrees. To solve folder waterlines, we need to improve the flow of material, taking a high melt temperature, high mold temperature, or change the water level and other methods. Such as forming the heat level or flame retardant materials, production 3-7 days after the remnants of a plastic mold surface will decomposition, leading to mold surface shiny, the need for timely clean up the mold, the mold surface while the need to increase the exhaust position. Cooling fast, die casting system should be thick, short for the principle should be established cold-slug, the gate should be large, such as: direct gate, disc gate or fan gate, etc., but should prevent stress increases , can be used to adjust the gates when necessary. Mold should be heated, wear-resistant steel should be used. Material temperature greater impact on the quality of plastic, the material temperature is too low will result in lack of material, matte, silver disorders too easy to overflow edge temperature materials, bars, silver and dark, discolored plastic bubble. Mold temperature great influence on the quality of plastic parts, mold temperature is low shrinkage, elongation, impact strength, flexural, compressive strength, tensile strength is low. Die temperature exceeds 120 degrees, the slow cooling of plastic parts, easy to stick mold deformation, stripping difficulties, long molding cycle. Small mold shrinkage, prone to melt cracking, stress concentration, thus forming conditions should be strictly controlled molding, molded plastic parts should be annealed. High melting temperature, high viscosity, shear effect is not sensitive to more than 200 grams of plastic parts should be used screw injection machine nozzle should be heated, it is appropriate to extend nozzle cheerful style, high-speed injection speed. ABS Application: level and use ABS for different uses can be divided into general level (including anti-leveling), flame retardant, heat-resistant grade, electroplating grade, transparent level, structural foam level and modified ABS and so on. Universal grade for the manufacture of gears, bearings, handles, machine housings and parts, all kinds of instruments, computers, tape recorders, televisions, phones and other housing and toys; flame retardant used in the manufacture of electronic components, such as computer terminals, machine housings and all kinds of household products; structural foam grade for the manufacture of the electronic device housing and the like; heat level for the manufacture of power plant automation instrumentation and motor housing, etc; plating grade for the manufacture of automotive parts, various knobs, nameplate, decorations and daily necessities; FAQ transparency level for the manufacture of disks, disk and other food in the refrigerator to answer 1, the price can then offer more? A: Our company adhering to the "puerile" business philosophy in the survival and development, quality and reasonable price, is your best choice. 2, it can offer free samples? A: The part is possible, but most of the original package of raw materials can not offer free samples, because the original package of raw materials, once dismantled, other customers will not accept it. But if the customer really are sincere long-term cooperation, we will consider providing free samples, as appropriate, within 3KG. Specific circumstances may consult online Want. 3. Sample including shipping it? A: The sample is not including shipping, oh, oh needs of customers take care of themselves! 4, professional and technical personnel to solve the after-sales problem? A: Yes, I have a professional Secretary of the technical staff to help customers solve the various problems encountered in molding, but requires customers to fully cooperate with the assist. 5, can provide ticket? A: Yes, our company can provide regular for the materials 17% VAT, if necessary, please contact online Want billing or telephone negotiations. 6, can provide SGS, UL yellow card, certificate of qualification information? A: Yes, for the Division I material can provide information on relevant qualifications.
