Organic bismuthA safe and environmentally friendly catalyst for polyurethane products such as hard foam, soft foam and CASE, organic Bismuth catalysts have been around for over 30 years. We developed a series of organobismuth catalysts to replace the toxic mercury-lead catalysts that were the mainstream at the time. These environmentally friendly organic bismuth, organic zinc and organic zirconium as well as composite metal catalysts can be cured at room temperature or heated, and are today’s leading players in the polyurethane industry in foam plastics, The alternative to toxic lead, mercury and tin catalysts in the production of coatings, adhesives, sealants and elastomer products.
Organic bismuth can be applied to runways. The advantages are:
(1) The performance of runway materials is better. Compared with lead, the same hardness can be increased by 2-6A, and tensile strength, tear strength, elongation and other indicators can be increased by 10%-25%. Therefore, the usage of TDI (MDI) and MOCA can be saved.
(2) The runway is more environmentally friendly. The product does not contain cadmium, lead, mercury, chromium and other heavy metals. It can not only meet the on-site construction process requirements, but also eliminate Pb and Hg pollution during the production and use of polyurethane plastic track materials. The track can meet the most stringent US and EU standards. , can be exported completely.
(3) The runway is easy to operate. Add it directly without affecting the construction and process.
(4) The runway is cost-effective. The addition amount is 0.4-0.8%, and the price is cheaper than mercury and rare earth catalysts.
(5) The runway is tasteless. Most of the odor is caused by incomplete reaction, and whether the reaction is complete or not depends on the correct choice of catalyst. Valikat Bi2010 reacts more completely, so it has less or no odor. After curing, even the glue using TDI raw materials has no smell, is safe and environmentally friendly, and reduces or eliminates hazards to constructors and users.
(6) Organobismuth catalyst improves the aging resistance of the runway. Compared with lead, the track color has better durability and the aging resistance is improved by 15%-30%.
