Chemical Name: Acrylonitrile-Butadiene-Styrene
Physical and Chemical Properties
High rubber content ABS EB-168 and EB-169 is an terpolymer of acrylonitrile-butadiene-styrene, which is a core-shell structure. The high rubber content of the product is 60-65%. In the production of general-purpose ABS, only 23-28% high rubber powder is needed to achieve the required performance index. If low rubber powder is used, 28-33% is needed, so the cost can be reduced by using high rubber powder.
High Rubber Powder
In 20 kg bags or 500 kg bulk bags
1. For general grade ABS, this product can be
directly mixed and granulated with SAN,it
is recommended to use DAQING SAN-327 and GUOHENG SAN-168 as they have the best
matching of nitrile content and high rubber powder, and conform to the similar
compatibility law. The mixing ratio is generally 23-28:77-72, which can reach
the ideal physical property index (other additives are added according to the
normal ratio, the internal lubricant is 0.8-1.0, the external lubricant is about
0.5, and the antioxidant is about 0.3).
2. To make modified ABS
products, as to make general ABS,
ABS high rubber needs to be mixed with SAN, the only difference is to add other
additives at the same time of mixing, such as flame retardant ABS, which needs
to add flame retardant and flame retardant synergist (typical formula: ABS
powder 30% - 40%, SAN, flame retardant and auxiliary 70% - 60%); to make heat-resistant
ABS, it needs to add additional heat-resistant components;to make glass fiber
ABS, it needs to add additional glass Fiber filler.
ABS recycles; PC / ABS recycle, and etc.
matter the new materials or recycles, the impact strength is provided by rubber
powder .The impact strength of recycled rubber decreases greatly due to the
aging of butadiene in rubber, so the impact strength can be enhanced by adding
new rubber powder.
