LX-50 light calcium carbonate
                  LX-50 is spindly crystal. The L/D ratio is 1:5. The main content of calcium carbonate is high. The product oil absorption quantity is high. It is suitable for natural rubber, butadiene styrene rubber, butadiene rubber, synthesis rubber, etc. It can improve the elongation, bending resistance, air impermeability and thermal aging performance of rubber products. Thus greatly improve the tensile strength and tear strength resistance of rubber. It can greatly improve rubber’s hardness, toughness, fineness and astigmatism insulation performance. It can improve the strength and volume, and decrease the production cost. Due to its high dispersion performance, this product is also used in coating, papermaking and other areas.
