The material selection for oil seals is crucial as it determines their performance, durability, and compatibility with various fluids. Common materials used in oil seals include nitrile rubber, fluoroelastomers, silicone rubber, and polytetrafluoroethylene (PTFE). Nitrile rubber is widely used due to its good chemical resistance, oil resistance, and moderate temperature range Nitrile rubber is widely used due to its good chemical resistance, oil resistance, and moderate temperature range

oil seal tcn. Fluoroelastomers, such as Viton, offer excellent chemical and heat resistance but are more expensive. Silicone rubber is known for its flexibility and resistance to extreme temperatures, while PTFE is highly resistant to chemicals and has low friction coefficients.


One of the primary benefits of using a long back heating pad is the effective relief from pain and muscle tension
. The moist or dry heat generated from these pads penetrates deep into the muscles, helping to increase blood flow and promote relaxation. This process not only alleviates existing pain but also helps to prevent muscle stiffness, making it an ideal solution for individuals who lead a sedentary lifestyle or those who engage in physically demanding jobs.Heat therapy is one of the most common uses for backache pads
. When applied to the back, warmth helps relax tight muscles, which can significantly reduce pain and discomfort. Heat increases blood flow to the area, bringing essential nutrients and oxygen that promote healing. It is particularly effective for chronic pain conditions, where muscle stiffness is often a contributing factor.
