成型特性：
1.无定形料,流动性中等,吸湿大,必须充分干燥,表面要求光泽的塑件须长时间预热干燥80-90度,3小时.
2.宜取高料温,高模温,但料温过高易分解(分解温度为>270度).对精度较高的塑件,模温宜取50-60度,对高光泽.耐热塑件,模温宜取60-80度.
3、如需解决夹水纹，需提高材料的流动性，采取高料温、高模温，或者改变入水位等方法。
4、如成形耐热级或阻燃级材料，生产3-7天后模具表面会残存塑料分解物，导致模具表面发亮，需对模具及时进行清理，同时模具表面需增加排气位置。
ABS树脂是目前产量，应用最广泛的聚合物，它将PS，SAN，BS的各种性能有机地统一起来，兼具韧，硬，刚相均衡的优良力学性能。ABS是丙烯腈、丁二烯和苯乙烯的三元共聚物，A代表丙烯腈，B代表丁二烯，S代表苯乙烯。
ABS工程塑料一般是不透明的，外观呈浅象牙色、无毒、无味，兼有韧、硬、刚的特性，燃烧缓慢，火焰呈黄色，有黑烟，燃烧后塑料软化、烧焦，发出特殊的肉桂气味，但无熔融滴落现象。
ABS工程塑料具有优良的综合性能，有极好的冲击强度、尺寸稳定性好、电性能、耐磨性、抗化学药品性、染色性，散热性（现在ABS工程塑料的工艺已经很成熟了，笔记本电脑只要内部结构设计合理，同样可以有出色的散热效果。)
成型加工和机械加工较好。ABS树脂耐水、无机盐、碱和酸类，不溶于大部分醇类和烃类溶剂，而容易溶于醛、酮、酯和某些氯代烃中。
ABS工程塑料的缺点：热变形温度较低，可燃，耐候性较差。
ABS plastic
Chemical Name: acrylonitrile - butadiene - styrene copolymer
English name: Acrylonitrile Butadiene Styrene (ABS)
Uses: auto parts (dashboard, tools, doors, wheel covers, mirror boxes, etc.), radio shell, telephone handles, high-intensity tools (vacuum cleaners, hair dryers, blenders, lawn mower, etc.), typewriter keyboard,recreational vehicles such as golf carts and jet skis cars.
Weight: 1.05 grams / cubic centimeter
Burning Identification Method: continuous burning, blue yellow flame, smoke, light marigold taste
Solvent Experiment: cyclohexanone can be softened and aromatic solvents had no effect
Drying Conditions :80-90 ℃ 2 Xiaoshi
Molding shrinkage rate 0.4-0.7%
Mold Temperature :25-70 ℃ (mold temperature will affect the finish of plastic parts, while lower temperatures lead to finish lower)
Melting temperature :130-160 ℃ or higher (depending on the different models may be)
Molding temperature :200-240 ℃
Injection speed: in high-speed
Injection Pressure :500-1000bar
Features:
A comprehensive performance is better, higher impact strength, chemical stability, good electrical properties.
2, and 372 of the melting plexiglass good, made of two-color plastic parts, and can be chrome plated, spray-paint treatment.
3, there are high-impact, high heat resistance, flame retardant, enhanced level of transparency and so on.
4, mobility was almost more than HIPS than PMMA, PC and so good, flexibility is good.
5, use: suitable for production of general machinery parts, reducing wear wear-resistant parts, transmission parts and telecommunication parts.
6, with the PVC (polyvinyl chloride) in the inflection at the same bleaching occurs.
Forming characteristics:
1. Amorphous materials, liquid medium, moisture large, must be fully dry the surface gloss of the plastic parts required to be a long warm-dry 80-90 degrees, 3 hours.
2. Advised to take the high-temperature materials, high mold temperature, but the expected high temperature and easy decomposition (decomposition temperature is "270 degrees). Pairs of high precision plastic parts, mold Wenyi take 50-60 degrees, high gloss. Resistancethermoplastic parts, mold Wenyi take 60-80 degrees.
3, To solve the clip Watermark, need to improve material flow, is expected to take a high-temperature, high mold temperature, or to change into the water and other methods.
4, such as forming heat-or flame-retardant grade material, production and 3-7 days after the remnants of plastic mold surface decomposition, leading to mold surface shiny, should take time to clean up mold, and mold surface, the need to increase the exhaust position.
ABS resin is the output of the largest and most widely used polymers, it PS, SAN, BS a variety of properties of organically united, both tough and hard, just relative to the fine balance of mechanical properties.ABS is acrylonitrile, butadiene and styrene terpolymer, A representative of acrylonitrile, B on behalf of butadiene, S on behalf of styrene.
ABS engineering plastics are generally opaque, the appearance of pale ivory, non-toxic, tasteless, both tough, hard, just features, burning slowly, the flame was yellow, with black smoke, burning plastic, after softening, charred, issue a specialthe cinnamon smell, but no melt dripping behavior.
ABS engineering plastic with excellent overall performance, with excellent impact strength, dimensional stability, electrical properties, wear resistance, anti-chemical nature, dyeability, heat dissipation (now ABS engineering plastics process is already very mature, andnotebook computers as long as the internal structure of reasonable design, can also have an excellent cooling effect.)
Forming and machining better.ABS resin, water, inorganic salts, alkalis and acids, insoluble in most alcohols and hydrocarbon solvents, and easily soluble in aldehydes, ketones, esters and certain chlorinated hydrocarbons.
ABS engineering plastic of shortcomings: a low heat distortion temperature, flammable, weather is poor.
