ABS is acrylonitrile-butadiene-styrene copolymer. The thermal deformation temperature of the modified ABS plastic is 93~118℃, and the product can be raised by about 10℃ after annealing. Use within the temperature range. However, in order to make the material meet the requirements of use, it is usually only to improve the heat resistance of modified ABS plastics, thereby broadening its non-application fields. Why should the heat resistance of modified ABS plastics be improved? Modified ABS plastics have good processability and toughness, but insufficient heat resistance, thus limiting its application range. Under normal circumstances, the Vicat softening point of modified ABS plastics is around 95 ℃, and the heat-resistant ABS exceeds 100 ℃. Therefore, it is very necessary to improve the heat resistance of modified ABS plastics to expand its application fields. Especially in the field of automobiles and electronic appliances, for automotive interior parts such as instrument panels, tool boxes, ashtrays, new extrusions and other components; automotive exterior parts, such as car bases, painted rearview mirror door panel components, spoilers, transmissions Box covers, etc., all require good heat resistance.
