Rubber Vulcanization- DBPH
USES: Vulcanizing agent, used for silicone rubber, polyurethane rubber, ethyl-propylene rubber, and other rubber, can improve the tensile strength and hardness of products, and the elongation and compression deformation are low, the smell after vulcanization in alkyl peroxide is the smallest. Its usage can be mixed in the rubber material when mixing. Crosslinking agent, can be used for polyethylene; Unsaturated polyester curing agent. The tensile strength and hardness of the products are high. Storage method: Open fire is strictly prohibited in storage sites, away from heat sources, to prevent static electricity, direct sunlight ( exposure to the sun ) and violent impact; Stay away from fire sources, acidic, alkaline and flammable materials. Should have good ventilation, room temperature should be under 25 ℃ storage.
Product profile and application: 1. WS sulfide resin is a kind of thermal reaction octyl phenolic resin with hydroxymethyl at both ends. 2. Mainly vulcanized butyl rubber, ethylene-propylene diene rubber, nitrile butadiene rubber, neoprene rubber, natural rubber, etc. 3. Soluble in toluene, xylene, ethane, ketones and other aromatic solvents and aliphatic solvents. 4. WS vulcanized resin is mainly used for tire capsule, air tire, medical butyl rubber plug, sealing rubber ring, rubber tube and other rubber products, can be directly added to the rubber during mixing, vulcanized rubber has excellent high heat resistance, high pressure, aging resistance.
Trait： This product is white crystalline powder; Has special odor. It is soluble in acetone or chloroform, slightly soluble in methanol or ethanol, and slightly dissolved in water. Main purpose： Used as plastic catalyst, oil refining, wax decolorization, pharmaceutical manufacturing, etc. It is used as initiator for polymerization and photochemical reaction of ene monomers (vinyl chloride, acrylonitrile, etc.). Flour, grease, wax bleach, cosmetic additives, rubber vulcanizer. Synthetic resin initiator. Flour, grease, wax bleach, cosmetic additives, rubber vulcanizer. Benzoyl peroxide can play a bleaching and anti-corrosion role in flour, benzoyl peroxide has been evaluated, at the same time, the bleaching and anti-corrosion of flour also has a very positive effect, some studies believe that it has a certain negative effect on the human body. Storage: 1. store in a cool and ventilated space with the storage temperature not exceeding 30 ℃. 2. Away from fire, heat source. It should be stored separately with acids, reducing agents, flammable substances, combustible substances, reducing agents, etc. 3. The lighting and ventilation facilities in the storage room are explosion-proof, and the switch is located outdoors. 4. Handling should be carefully placed, to prevent packaging and container damage, prohibit impact and oscillation, packaging and handling operations should pay attention to personal protection. Note: keep the package sealed and avoid danger caused by water loss.
Sodium- MBT (Na MBT)
Mainly used in the manufacture of tires, tape, rubber shoes and other industrial rubber products. This product is the rubber industry universal type accelerator, has the quick vulcanization function to the natural glue and the general sulfur vulcanization synthetic glue. In natural gum and styrene butadiene latex as promoter of dithiocarbamate. Easy to disperse in rubber, no pollution, suitable for natural vulcanized rubber paste and hot water vulcanized products. The solution made of water and alcohol can be used as corrosion inhibitor for steel, copper and aluminum products. Storage Storage for six months in dry and cooling place.
