Basic magnesium sulfate whisker

(model: ws-1s2)

[product summary]

This product is a new type of inorganic flame retardant and reinforced fiber material with single crystal structure. Compared with composite plastics, it has obvious reinforcing, stiffening and flame retardant effects. It can make the parts have high deformation temperature, smooth and beautiful surface, reduce the proportion of parts, and non-toxic and environmental protection. The micro and special single crystal fiber structure is especially suitable for the reinforcement and stiffening of ultra-thin parts and micro parts. This product can also give the products good scratch resistance and anti-skid, to meet the needs of automobile and other engineering plastics spraying free. When used as flame retardant, the temperature is higher than that of aluminum hydroxide, which can inhibit smoking and prevent dripping. It can also be used as tackifying coating, flame retardant asphalt, flame retardant paper, light PVC composite floor, PVC foam and other building materials and efficient filter materials. The initial decomposition temperature of basic magnesium sulfate whisker is 260 ℃, when heated to 900 ℃, the final product is MgO, which can be used for engineering plastics with processing temperature of about 250 ℃.

This product is weakly alkaline and soluble in acidic system. If inhaled into the lung, it can dissolve in body fluid for a period of time. Therefore, it is relatively safe. It will not cause lung lesions like asbestos and endanger life safety. It is recognized as one of the safest and most suitable new materials to replace asbestos.
