Chemical name of ABS plastic: Acrylonitrile-butadiene-styrene polymer English name: Acrylonitrile Butadiene Styrene Specific gravity: 1.05 g/cubic centimeter Molding shrinkage: 0.4-0.7 Molding temperature: 200 -240℃ Drying conditions: 80-90℃ 2 hours Features: 1. Good comprehensive performance, high impact strength, chemical stability, good electrical properties. 2. Good weldability with 372 organic glass, making two-color plastic parts , and can be surface chrome plated and spray painted. 3. There are high impact resistance, high heat resistance, flame retardant, reinforced, transparent and other levels. 4. The fluidity is slightly worse than HIPS, better than PMMA, PC, etc., and has good flexibility. Uses : Suitable for making general mechanical parts, wear-reducing and wear-resistant parts, transmission parts and telecommunication parts. Molding characteristics: 1. Amorphous material, medium fluidity, large moisture absorption, must be fully dried, plastic parts requiring glossy surface must be pre-prepared for a long time Heat drying at 80-90 degrees for 3 hours. 2. It is advisable to use high material temperature and high mold temperature, but if the material temperature is too high, it will easily decompose (decomposition temperature is gt; 270 degrees). For plastic parts with higher precision, the mold temperature should be Take 50-60 degrees. For high-gloss and heat-resistant plastic parts, the mold temperature should be 60-80 degrees. 3. If you need to solve the problem of water marks, you need to improve the fluidity of the material, adopt high material temperature, high mold temperature, or Methods such as changing the water level. 4. If heat-resistant or flame-retardant materials are formed, plastic decomposition will remain on the mold surface after 3-7 days of production, causing the mold surface to shine. The mold needs to be cleaned in time, and the mold surface needs to be increased Exhaust position. ABS resin is currently the polymer with the largest output and the most widely used. It organically unifies the various properties of PS, SAN, and BS, and has excellent mechanical properties of toughness, hardness, and rigid phase balance. ABS is A terpolymer of acrylonitrile, butadiene and styrene, A represents acrylonitrile, B represents butadiene, and S represents styrene. ABS engineering plastics are generally opaque, light ivory in appearance, and non-toxic , odorless, with tough, hard, and rigid characteristics. It burns slowly, with a yellow flame and black smoke. After burning, the plastic softens and burns, giving off a special cinnamon smell, but there is no melting and dripping phenomenon. ABS engineering plastics have excellent Its comprehensive properties include excellent impact strength, good dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, and good molding and mechanical processing. ABS resin is resistant to water, inorganic salts, alkali and acids. , insoluble in most alcohols and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and some chlorinated hydrocarbons. Disadvantages of ABS engineering plastics: low heat distortion temperature, flammable, poor weather resistance.
