1 Physical characteristics 1. Products rubber content in 55-70%, in the production of general purpose grade ABS, just add 23-28% of high powder can achieve the required performance, if low powder must be added 28-33%, so Use high powder can reduce costs. 2. Nitrile content, products nitrile content of about 26-28%, polar, easy coloring, chemical resistance, rigid ABS production, improve gloss. 3. High heat distortion temperature with high powder production of generic ABS, heat distortion temperature greatly improved in 92-95 ℃, much higher than the national standard, and compared to other manufacturers products has obvious advantages. 4. High melt index produced by ABS high powder melt index higher, mobility, and ease of processing. 2 General Purpose 1. a general purpose grade ABS, SAN directly blended with granulated recommended Daqing SAN-327, States Hang SAN-168, because of their high nitrile content and powder to match the best, in line with similar compatible law. The blend ratio is generally 23-28: 77-72, to achieve the desired physical indicators (the normal ratio of other additives added 0.8-1.0 internal lubricant and external lubricant 0.5, antioxidants around 0.3). In fact China is now widely used by manufacturers of ABS emulsion graft body SAN blending method would need to get ABS and SAN blended rubber powder, so the market has Daqing, the new lake, States Hang, Taiwan and other brands of high powder not surprising, because the ABS high powder originally upstream product, can continue down a general purpose ABS, you can also come up for sale as a finished product. 2. do modified ABS products, with a general purpose, like ABS, ABS and SAN requires high powder blending, the only difference is that while in a blender together with other additives, such as do flame ABS, you need to add flame retardants and flame-retardant synergist (typical formula: ABS powder 30% -40%, SAN, flame retardants, additives 70% --- 60%); make heat resistant ABS require additional components added; do including fiberglass ABS extra added glass filler. 3. ABS alloy made products, such as [1], PA / ABS alloy, PMMA / ABS alloy, PBT / ABS alloy, called alloys, nothing more than to two or more materials in accordance with a certain proportion of physical blending, learn from each other to give a more comprehensive performance excellent material. As one of the ABS component is concerned, the same requirements as SAN and high powder blend to get; the only difference is, the smaller the proportion of the alloy, such as the production of PC alloy, high powder generally requires 8 -12 parts (typical formula: ABS powder 30% -50%, SAN, PC, auxiliaries 70% --- 50%), performance indicators, the impact reached 600J / m, heat distortion temperature of 110 ℃, Rockwell hardness around 110. 4. toughened ABS back materials, PC / ABS back materials, etc., regardless of the new material back to the material, the impact strength are rubber powder provided material back due to the aging of butadiene rubber, impact strength decreased very powerful, you can add The new powder to enhance its impact strength. 5. toughened PVC, PC material.
