We know that rubber sealing strip is an indispensable sealing product in our life and production. With it, we don't have to worry about air leakage, water leakage and air leakage. So such important things will have different characteristics because materials are not used. Let's introduce them one by one.
1. Natural rubber sealing strip: applicable temperature is - 50 ~ 120 ℃; It is characterized by good elasticity and low temperature performance, but poor high temperature performance, poor oil resistance and easy aging in the air.
2. Styrene butadiene rubber sealing strip: applicable temperature is - 30 ~ 120 ℃; It is characterized by resistance to animal and vegetable oil, large expansion to general mineral oil, strong aging resistance, and better wear resistance than natural rubber sealing strip.
3. Nitrile rubber sealing strip: applicable temperature is - 30 ~ 120 ℃; It is characterized by good oil resistance, wear resistance and aging resistance, but it is not suitable for machinery of phosphate ester hydraulic oil.
4. Silicone rubber sealing strip: applicable temperature is - 20 ~ 120 ℃; It is characterized by high content of fuel oil, gasoline and mineral oil, good oil resistance, but poor cold resistance.
5. Ethylene propylene rubber sealing strip: applicable temperature is - 50 ~ 150 ℃; Heat resistance, cold resistance, aging resistance, ozone resistance, acid and alkali resistance, good wear resistance, but not resistant to general mineral oil lubricating oil and hydraulic oil.
