Yourun is one of the companies that produce the largest variety of organic bismuth catalyst in the world. Besides the general purpose bismuth catalyst, You run also supplies bismuth catalyst for specific purposes, such as TPU, polyester, low VOC, reactive organic bismuth, etc. Yourun Organic Bismuth Catalysts are divided into conventional type and innovation type, which have different application fields.     
General features of organic bismuth catalyst          :
Environmental protection: meet the requirements of international environmental protection regulations
Promote NCO / OH reaction, reduce the side reaction between water and - NCO and reduce the generation of CO2 compared with organic tin catalyst; However, the selectivity of reducing the reaction between isocyanate and water is not as good as CUCAT series catalysts.     
The catalytic activity is quite high, but lower than that of organic tin catalyst.
It is easy to hydrolyze and inactivate in water, but it is more stable than T-9; For hydrolysis resistant and eco-friendly catalysts, please select AUCAT series.     
It will affect transparency when used in polyester system. AUCAT series is recommended for polyester system.
The flowable time is short in the early stage and the strength increases slowly in the later stage.
Classification of organic bismuth catalysts: it is subdivided into five sub series of BCAT          , BCAT-A,BCAT-B, BCAT-C and BCAT-T, with dozens of models.Yourun is one of the companies that produce the largest variety of organic bismuth catalyst in the world. In addition to products that have no difference with imported brands of organic bismuth, it also provides products for special or specific purposes, such as TPU, polyester, low VOC, reactive organic bismuth, etc.
