PC engineering plastics is a kind of SABIC engineering plastics. In recent years, PC engineering plastics have been rapidly developed in china, and its industrial system has been gradually established and improved. mainly because of the rapid development of the domestic economy and the continuous promotion of plastic instead of steel and wood. the filler is an important auxiliary material in the plastics industry. at present, the filling modification of PC engineering plastics properties of hongtu has the following advantages:

One is to improve the heat resistance of PC modified plastics. general engineering plastics have low heat resistance, and their long-term use temperature is only about 60 ° C, while most of the fillers are high temperature resistant inorganic materials, so these fillers can greatly improve the heat resistance of plastics. for example, when PC is not filled modified, its thermal deformation temperature is about 110 ° C, and when filled with 30% talc, the thermal deformation temperature of PC modified plastics can be improved to more than 130 ° C.

The second is to improve the hardness of PC modified plastics. the rigidity of general plastics is poor, such as the bending modulus of pure PC is about 1000MPa, which is far from satisfying the requirements of some parts, and when 30% of talc is involved, its bending modulus can reach more than 2000MPa, indicating that talc has a significant enhancement effect on PC-modified plastics.

The third is to reduce costs. In general, the filler is cheaper than the resin, and the participation of the filler can greatly reduce the cost of PC modified plastics, which has obvious economic benefits, which is also the primary reason for the popularity of plastic filling modification. In addition, some fillers have certain effects on plastics, giving plastics some functions and improving the added value of plastics.
