The application and performance of all kinds of o ring?
Do you know the use and performance of various high temperature resistant rubber seals?Today we're going to talk about that.
At present, there are many kinds of high temperature resistant rubber sealing strips. According to the different raw materials used, they can be divided into NBR butadiene rubber sealing strips, HNBR Hydrogenated Butadiene rubber sealing strips, SIL silicone rubber sealing strips, VITON fluorosilicone rubber sealing strips and FLS fluorosilicone rubber sealing strips.
NBR butadiene rubber seal temperature range is -40~120° C, mainly used in gasoline, water, silicone oil and other media, its use range is very wide, and the cost is relatively low, so it is welcomed by many users.But it is not suitable for ketones, ozone, nitrohydrocarbons and other polar solvents.
HNBR hydrobutadiene rubber seal strip has a temperature tolerance range of -40~150℃. It is mainly used in automobile engine system and washing machinery system, but not suitable for alcohol, ester and other solutions.It has good oxidation resistance, wear resistance, tear resistance, corrosion resistance.
The temperature resistance range of SIL silicone rubber sealing strip is -55~250℃.It is mainly used in all kinds of household appliances, especially those products that need direct contact with human body, such as water dispensers and hot water bottles.As it is not oil resistant, it is not suitable for use in media containing oil.It has han Hao's cold and heat resistance, and excellent insulation.
The temperature resistance range of FKM fluorin rubber sealing strip is -20~280℃. It is mainly used in the sealing of engines, chemical plants and fuel systems, because it has a good resistance to many oil products and solvents, so it is very suitable for the sealing of acids, aliphatic hydrocarbons, aromatic hydrocarbons.It has good chemical resistance, ozone resistance.
FLS fluorosilicone rubber sealing strip temperature range is -50~260℃, it is often used in aviation, aerospace and military above, its characteristics are mainly high temperature resistance, low temperature resistance, solvent resistance, oil resistance.
