Recently, incidents of “poisonous plastic runways” have occurred frequently in Jiangsu and other places. Relevant departments have detected toxic substances left on the runways after construction. Primary school students with poor resistance will suffer symptoms such as dizziness and nosebleeds when traveling, which is seriously harmful. Student health. How to ban “toxic tracks” and return students to a green and environmentally friendly sports venue requires strict control of each raw material, including catalysts. The organobismuth catalyst was launched, which does not contain cadmium, lead, mercury, chromium and other heavy metals. The addition amount is 0.04%-0.08%. It can completely replace the commonly used The organic Pb/Hg, Pb/Zn and other heavy metal composite catalysts 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. It is an ideal raw material for environmentally friendly plastic tracks. Many engineering teams are using our product and have received positive feedback.
Special environmentally friendly catalyst for polyurethane runways, organic bismuth Valikat2010
Product parameters: Product density: 1100-1200kg/m3 Flash point: 110℃ Metal content : 19.3-20.7% Color: light yellow liquid
Product features: This product is specially developed for polyurethane track materials. It is an excellent choice to ban “toxic plastic tracks”. The product does not contain heavy metals restricted by Europe and the United States. The product has the following characteristics:
(1) The track material has better performance. 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 requirements of on-site construction technology, 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 craftsmanship.
(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) Organic bismuth catalyst improves the aging resistance of the runway. Compared with lead, the runway color has better durability and the aging resistance is improved by 15%-30%
