White or light yellow powder, bitter non-toxic, insoluble in water, soluble in ethanol, ether, etc.
Light yellow monoclinic acicular or flake crystalline powder, slightly smelly and bitter, 1.42 relative density. Melting point 170~181 ℃. Soluble in acetone, ethyl acetate, dichloromethane, ethanol and sodium hydroxide and sodium carbonate and other alkaline solution. Slightly soluble in benzene, insoluble in water and gasoline. Combustible, dust-like explosion hazard. Low toxicity, LD50 5000 mg/kg.
Rubber accelerator SDBC(TP) natural rubber, styrene butadiene rubber, neoprene rubber and super accelerator for latex. The curing speed is slower than ammonium dithiocarbamate salt, and the scorch time is longer. Because it is miscible with water, it is suitable for latex products.
The rubber reinforcing resin is CH-STA a non-reactive type novolac resin. It does not contain HMT and is a reinforced resin modified by tall oil rosin.
Alumina nozzle has good insulation, thermal insulation and wear resistance, because the price is relatively cheap, and its comprehensive performance balance, is one of the most widely used ceramic materials
Stearic acid plays an important role in the synthesis and processing of rubber. Stearic acid is a widely used vulcanizing agent in natural rubber, synthetic rubber and latex, and can also be used as a plasticizer and softener.
Zirconia ceramic sieve plate with ZrO2 as the main component, according to the addition of stabilizers, mainly yttrium stabilized zirconia, magnesium stabilized zirconia and cerium stabilized zirconia. Zirconia ceramics usually have high mechanical strength and fracture toughness, and have good corrosion resistance. Magnesium stabilized zirconia still maintains good mechanical properties at high temperature (600 ℃).
The rubber accelerator TBzTD is a safe secondary amine accelerator, which is mainly used to replace the thiuram additive TMTD.
