Dibutyltin dilaurate is an organic tin additive that is soluble in organic solvents such as benzene, toluene, carbon tetrachloride, ethyl acetate, chloroform, acetone, petroleum ether, and all industrial plasticizers. It is insoluble in water. The high boiling point and multi-purpose organic tin catalysts circulating on the market, dibutyltin dilaurate, are usually subjected to special liquefaction treatment. They are light yellow or colorless oily liquids at room temperature and white crystals at low temperatures. They can be used as additives for polyvinyl chloride plastics and have excellent lubrication, transparency, and weather resistance. Good resistance to sulfide pollution. It can be used as a stabilizer in soft transparent products, an efficient lubricant in hard transparent products, a catalyst for crosslinking reaction of acrylate rubber and carboxyl rubber, synthesis of polyurethane foam and polyester, and a catalyst for room temperature vulcanized silicone rubber.
Chemical properties: Light yellow transparent flammable liquid. Soluble in acetone and benzene, insoluble in water.
Use: used as heat stabilizer for PVC, curing agent for silicone rubber, catalyst for polyurethane foam, etc
Used as a plastic stabilizer and rubber curing agent
It can be used as a heat stabilizer for polyvinyl chloride and is the earliest variety of organic tin stabilizers. It is not as heat-resistant as butyl tin maleate, but has excellent lubrication, weather resistance, and transparency. It has good compatibility with plasticizers, does not spray frost, has no sulfur pollution, and has no adverse effects on heat sealing and printing properties. Due to its liquid nature at room temperature, it has better dispersibility in plastics compared to solid stabilizers. This product is mainly used for soft and transparent products or semi soft products, with a general dosage of 1-2%. It has a synergistic effect with metal soaps or epoxy compounds such as cadmium stearate and barium stearate. In hard products, this product can be used as a lubricant in combination with organic tin maleate or thiol based organic tin to improve the flowability of resin materials. Compared with other organic tin, this product has a higher initial coloring ability, which can cause yellowing and discoloration. This product can also be used as a catalyst for the synthesis of polyurethane materials and as a curing agent for silicone rubber. In order to improve the thermal stability, transparency, compatibility with resin, and enhance its impact strength when used in hard products, many modified varieties have been developed. Generally, fatty acids such as lauric acid are added to pure products, and some even include epoxy esters or other metal soap stabilizers. This product is toxic. The oral LD50 of rats is 175mg/kg.
