HIGH QUALITY FKM VITON 90SHORE-A BLACK /BROWN/GREEN ORING CORDS 20MM 50MM Diameter

Common processing techniques for FKM  rubber  oring cord  

1. Injection molding: Fluorine rubber using this process can use brands with low Mooney viscosity and medium Mooney viscosity (20-60MV), good scorch safety, and fast vulcanization speed.

2. Injection molding: Fluorine rubber using this process can use grades with low Mooney viscosity and medium Mooney viscosity (20-60MV) and good scorching safety to avoid scorching during the injection molding process.

3. Plate molding: Fluorine rubber using this process can use a brand with high Mooney viscosity (50-90MV) and fast vulcanization speed.

4. Extrusion molding: Fluorine rubber using this process can use a brand with low Mooney viscosity (20-40MV) and good scorching safety. In many cases, processing aids can be used to improve flowability and surface finish.

5. Coating molding: The viscosity of the solution is determined by the amount of solvent and filler selected. The stability of the solution (storage period) is the primary issue that needs to be considered.

Second stage vulcanization: In order to achieve optimal performance, the rubber is finally subjected to second stage vulcanization. The general second stage vulcanization condition is 230 ℃ @ 24h. However, the time and temperature of secondary vulcanization vary with different products, processing processes, and costs. For certain applications. Secondary vulcanization may not be used.

Application fields of FKM rubber  cords

The automotive, aerospace, petrochemical, and mechanical industries are the most widely used fields of fluororubber, with 60% to 70% of fluororubber used in the automotive industry. The 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 manufacturing industry find better and less permeable sealing materials to meet strict new automotive exhaust emission standards. Manufacturers of fuel systems and engine sealing gaskets have long focused on fluoroelastomers, which are used to manufacture sealing gaskets, hoses, engine air intakes, and oil resistant gaskets for fuel and transmission systems. At present, fluorine rubber in China is facing good development opportunities.
