Hebei Messi Biology Co., Ltd. relies on hydromagnesite resources to independently develop activated magnesium oxide 120 and 150 products. The magnesium oxide content is 98.0, density (g/cm3): 0.25, iodine absorption value (ml/g): 150, ratio Surface area (BET, m2/g): 145, Appearance: white powder, Packing: 20KG with outer plastic and inner braiding, Storage: ventilated and dry, pay attention to moisture-proof, please pay attention to seal the opening after use.
Hebei Messi Biology Co., Ltd. stated that activated magnesium oxide is filled in nitrile rubber and other rubber types as a reinforcing agent for heat-resistant rubber to improve heat resistance. Activated magnesium oxide has high purity and few impurities, and is especially suitable for products with strict requirements on heavy metals. Dosage: 2-15PHR. It can also be used for thermally conductive silicone sheets and thermally conductive resins PA6 and PPS. Through different particle size ratios, the thermal conductivity can reach up to 5W/m.K.
Activated magnesium oxide is high-purity magnesium oxide that is fully burned and reacted. It is chemically refined by calcining magnesite with water. It is an ultra-fine powder. And using special substances for surface treatment, the product has excellent polymerization and good dispersion properties, and is easy to be moisture-proof. In addition to being used as vulcanizing agent and activator, it can also be used as reinforcing filler. The activity value is as high as 150 and has strong acid absorption. It is especially suitable for vulcanization of rubber adhesives, natural rubber pressure-sensitive adhesives, styrene-butadiene rubber adhesives, nitrile rubber adhesives, fluorine rubber, chloroprene rubber, chloroprene glue, chlorosulfonation Polyethylene improves vulcanization performance and physical properties of products.
