Shanghai Xusen Non-halogen Smoke Suppressoning Fire Retardants Co.,Ltd. [ Gold Suppliers ]
Description As major inorganic fire retardants, aluminium hydroxide is listed in the first place because of its dosage. Its fire retardant and smoke suppressioning characteristic can reduce corrosive gas after burning, and it has good arc resistant and coercive force capability. At present, it becomes the ideal environmental product due to its non-toxic product and cheap price, and it accounts for about 45% of the total fire retardants wastage with a rapid development. With the wide application, there¡¯s a higher demand of aluminium hydroxide. There will be different demand of impact intensity, toughness, surface glabrousness, and process techniques and so on because it¡¯s large quantity of supplement. So we¡¯ll focus on ultra-fine treatment, distribution of particle size, surface modified, cladding, re-compound and so on in future. Our company has developed ultra-fine aluminium hydroxide on the basis of the fire retardants such as high foaming polyethylene, non-halogen fire retardants, and ep...
