Common specifications include 500ppm, 1000ppm, and so on up to 20000 - 200000ppm. This flexibility allows users to select the most appropriate specification based on their specific production needs, ensuring optimal performance and cost - efficiency.
The platinum catalyst is renowned for its high catalytic efficiency. It can effectively catalyze the addition cross - linking reaction between vinyl - containing siloxanes (e.g., vinyl silicone oils and vinyl - bearing raw rubbers) and hydrogen - containing siloxanes (such as hydrogen - containing silicone oils). In chemical reactions, it acts as a catalyst, reducing the activation energy required for the reaction to occur, thereby accelerating the reaction rate and improving the overall reaction efficiency.
Its applications are far - reaching and diverse. In the rubber industry, it is used in mold - pressing molding compounds, silicone tube extrusion compounds, and as a catalyst for vulcanizing machines. It serves as a key catalyst in the production of addition - type potting compounds, silicone sheets, mold compounds, printing transfer compounds, silicone inks, silicone resins, and silicone gels. Moreover, it plays a vital role as a catalyst in the synthesis of polyether - modified silicone oils and amino - silicone oils. It also functions as an additive in polyurethane coatings, organic silicone coatings, and defoamers, enhancing their performance characteristics.
