Product description:

Enhanced PC/ABS is mainly used in automotive parts, power tool housings and high dimensional stability parts, and the corresponding grades include HAC8250TC, HAC5010G, HAC5020G, and HAC5030G. The additive amount of glass fiber commonly used in the market to enhance PC/ABS is mostly below 30%, because adding too much glass fiber will cause a serious decrease in the surface gloss of the material, often manifested as exposed glass fiber. <1> Effect on tensile/flexural properties. With the increase of glass fiber content, the strength increases slowly, and the modulus increases obviously. <2> Influence of impact performance. Additive amount of 5% glass fiber makes the impact strength drop greatly, after that, the impact change is no longer obvious. <3> Influence of heat resistance. Glass fiber has limited impact on heat resistance, which is a major feature of amorphous materials. In addition, after adding glass fiber, the shrinkage rate of the material is reduced, and it is basically stable at 0.1%-0.3% after adding 20% glass fiber. After adding glass fiber, the surface gloss of the material will be seriously reduced. In order to improve the appearance, the methods often used including: adding additives, such as brightener, improving the flow of the material, selecting ultra-fine glass fiber, first making glass fiber master-batch and then secondary processing, etc.
