According to the chemical composition characteristics of PC/ABS alloy, you can use the special toughening agent for PC/ABS plastic alloy to improve the impact strength of PC/ABS plastic alloy through corresponding chemical and physical effects. Mainly used in various PC/ABS (including glass fiber reinforcement, flame retardant, halogen-free flame retardant, mineral filler, etc. ), in the case of a small amount of use, it can obviously improve the toughness of PC/ABS alloy and maintain other mechanical properties and hardness. Suitable for various molding methods and plastic products. There is a paper in the 6th issue of the Journal of Plastics Industry (20 1 1), which is entitled preparation and properties study of mineral reinforced PCABS alloy. The toughness of mineral reinforced PC/ABS alloy was effectively improved by using plastic toughening agent from Maanshan Keli Chemical Company.

High rubber powder is to improve the toughness of ABS. If fiber is added, it is to improve the rigidity of ABS. I don't know what kind of performance LZ will improve, just add a little PC.

It may be that PS is mixed in the ABS you returned, and it is most important to grasp the purity of the material. 5% high rubber powder or SEBS is enough.

To measure its impact resistance, it seems that there is a testing instrument called drop hammer impact, which should be similar to this principle.

There are many ways to improve the toughness of ABS, such as adding elastomer, mixing new materials and alloying.

The cost of adding PC will be a bit high, depending on the specific situation, generally 20-80 copies will be enough, but it is not recommended to inject directly after mixing, because it is easy to stratify, so it is best to inject after granulation, and the cost of adding elastomer and new materials is lower, especially adding new materials, which can be injected directly.
