1. Common processing technology of fluororubber 1. Injection molding: The fluororubber using this process can use the grades with low Mooney viscosity and medium Mooney viscosity (20-60MV), good scorch safety and fast vulcanization speed. 2. Injection molding: The fluororubber using this process can use low Mooney viscosity and medium Mooney viscosity (20-60MV), and the grades with good scorch safety are used to avoid scorch during the injection process. 3. Flat plate molding: The fluororubber using this process can use the grades with high Mooney viscosity (50-90MV) and fast vulcanization speed. 4. Extrusion molding: The fluororubber using this process can use low Mooney viscosity (20-40MV) and good scorch safety grades. Processing aids can be used in many cases to improve flow and surface finish. 5. Coating and molding: The viscosity of the solution is determined by the amount of solvent and filler selected. The stability of the solution (shelf life) is the primary issue to consider. ——Second-stage vulcanization: In order to achieve the best performance, the rubber seals
is finally subjected to two-stage vulcanization. The general secondary vulcanization conditions are 230℃@24h. However, the time and temperature of secondary vulcanization vary with different products, processing procedures and costs. for some applications. Secondary vulcanization may not be used. 2. The application fields of fluororubber Automobile, aerospace, petrochemical and machinery industries are the most widely used fields of fluororubber, and 60% to 70% of fluororubber is used in the automotive industry. Relevant regulations for automobiles will have a profound impact on the application of fluororubber. The biggest challenge for the fluoroelastomer production industry is to help the automotive industry find better and lower permeable sealing materials to meet stringent new automotive exhaust emission standards. Manufacturers of fuel system and engine gaskets have long focused on fluoroelastomers for fuel and transmission gaskets, hoses, engine air intakes and oil resistant gaskets. At present, my country's fluororubber is facing a good opportunity for development. Company website: https://www.orksealing.com/
