Rubber seal resistant to all kinds of media
Rubber is subdivided into many materials, of which nitrile rubber, silicone rubber, EPDM rubber, fluorine rubber are common materials in rubber seals, so what are the media they are resistant to? Next, Haisheng rubber takes you to understand what media are resistant to all kinds of rubber seals.
1, nitrile rubber seal ring: suitable for petroleum products, air with oil vapor, vegetable oil and mineral oil, but not suitable for phosphate series hydraulic oil and gear oil containing extreme pressure additives, the use temperature is -40-120℃.
2, silicone rubber sealing ring: suitable for drinking water, hot water, oil-free air to send high temperature steam, etc., but not suitable for petroleum medium, the use temperature is -60-230℃.
3, EPDM rubber sealing ring: suitable for hot water, dilute acid, oil-free air and a variety of chemicals, good weather resistance, but not suitable for petroleum media, the use temperature is -50-150℃.
4, fluorine rubber seal ring: suitable for a variety of hydrogenated acids, petroleum, halogen jing, lubricating oil, hydraulic device liquid, organic liquid and air containing hydrocarbons, the use of temperature is -20-150℃.
By understanding the different adhesive media, you can choose the adhesive according to the actual needs and the working environment of the rubber seal.
