1. Natural rubber sealing strip: suitable for temperatures ranging from -50 to 120 ℃; Its characteristics are good elasticity, good low-temperature performance, but poor high-temperature performance, poor oil resistance, and easy aging in the air.
2. Styrene butadiene rubber sealing strip: suitable for temperatures ranging from -30 to 120 ℃; Its characteristics are resistance to animal and vegetable oils, large expansion to general mineral oils, strong aging resistance, and better wear resistance than natural rubber sealing strips.
3. Nitrile rubber sealing strip: suitable for temperatures ranging from -30 to 120 ℃; Its characteristics are good oil resistance, wear resistance, and aging resistance, but it is not suitable for phosphate hydraulic oil machinery.
4. Silicone rubber sealing strip: suitable for temperatures ranging from -20 to 120 ℃; Its characteristics are fuel resistance, gasoline resistance, mineral oil resistance, high content, good oil resistance, but poor cold resistance.
5. Ethylene propylene rubber sealing strip: suitable for temperatures ranging from -50 to 150 ℃; Heat resistant, cold resistant, aging resistant, ozone resistant, acid and alkali resistant, wear-resistant, but not resistant to general mineral oil lubricants and hydraulic oils.
