The vulcanizing machine has high requirements for sealing, which requires low resistance, low wear and long life. In order to prevent gas leakage. So what are the commonly used sealing materials, the editor believes that there are three types:
1. Polyurethane rubber is a new type of rubber material widely used in various hydraulic cylinders at present. It has excellent physical properties and chemical stability, good strength, elasticity and oil resistance, and also has excellent wear resistance. Sex. Can withstand high pressure.
2. Oil-resistant rubber and cloth rubber: Nitrile rubber is the most used and has good elasticity
3. Polytetrafluoroethylene (plastic): The biggest feature is high heat resistance and good corrosion resistance.
The above three sealing materials are fully in line with the use in the vulcanizing machine and fully meet the requirements.
