High activity, so it can be mainly used for neoprene, fluorubber and butyl rubber as aaccelerant and activator. The activity of MgO can increase the crosslinking density, and then raise the physical property of rubber stopper. Good dispersibility, no coming off powder even at high dosage. Used in ceramics, enamel manufacture of advanced refractories. , Various types of heavy-metal contents are in line with the highest environmental protection requirements. 5, Package & storing: Package with double tier material, inside is plastic, and outside is plastic or paper package. The entire package has been securely sewed down. There are net weight 10kg, 15kgs, 20kgs and 1kg vacuum packing. Keep away from moisture, oxide, acid and halide during the shipping term, recommends delivery with the cover.
