ZR—250BA  Barium sulfate particles are resistant to strong acid, alkali corrosion characteristics, so it is mainly used for to the acid resistance and alkali corrosion of HDPE packaging container. It can improve the strength and rigidity of the drop test of 50 to 200 litre packaging barrel, and obviously reduce the material cost of the modified products. The added amount is about 15%
