Product name: special polyurethane magnesium hydroxide flame retardant
Implementation of the standards: HG/T3607--2007
Product brand: Honghai
Molecular formula: Mg (OH) 2
Product specification: 20kg
Molecular weight: 58.32
Appearance: white powder
Bulk density: 2.36g/cm ³
Products: environmentally friendly flame retardant smoke eliminating agent resistant metal filler
Product features: more than traditional aluminum hydroxide, this product has the following advantages:
① magnesium hydroxide by thermal decomposition temperature of up to 340 ℃, higher than that of aluminium hydroxide 100 ℃, help improve the plastics processing, speeds up the extrusion speed, improve plasticization and shorten the molding, surface high gloss, does not produce surface defects, and guaranteed with Super peeling strength.
Second, the particle size distribution, good compatibility with substrate, small effect on mechanical properties of products.
③ combustion generated after dehydration of magnesium hydroxide magnesium oxide is a high strength, high heat resistant material and can be used as a protective wall, cut off from the source of fire and poisonous gas, acid and magnesium hydroxide and strong, can quickly neutralize acid gases generated by combustion of plastics of SO2, NOx, CO2, etc.
④ high magnesium hydroxide decomposing capacity, high efficiency, and smoke suppression ability and hardness of the equipment less friction to help extend the life of equipment.
⑤ low prices, is cheaper than aluminum hydroxide and magnesium hydroxide filling volume, can greatly reduce the cost of products.
Physical characteristics: magnesium hydroxide is heated (340-490) absorbed and surface heat to the fire-retardant effect of combustion and release large amounts of water to dilute fuel surface oxygen, generated by the decomposition of activated magnesium oxide attached to combustible surface and prevents further burning. Hydrogen oxidation magnesium in whole flame retardant process in the not only no any harmful material produced, and its decomposition of product in flame retardant of while also can large absorption rubber, and plastic, polymer burning by produced of harmful gas and smoke, activity magnesium oxide constantly absorption not completely burning of melting residues real, from makes burning soon stop of while elimination smoke, and block melt drops, is a emerging of environmental type inorganic flame retardant agent.
