Weather resistance and sealing performance: Advantages of EPDM gaskets
As a sealing material widely used in construction, automobiles, electrical appliances and other fields, EPDM gaskets have good ozone resistance, heat resistance, weather resistance and other properties, and can maintain good use effects for a long time. This article will analyze its advantages from the two aspects of weather resistance and sealing performance.
First, from the perspective of weather resistance, EPDM gaskets have excellent weather resistance. EPDM (ethylene propylene rubber) is a highly saturated synthetic rubber with fewer unsaturated bonds in its molecular structure, which makes it less susceptible to aging, hardening or cracking due to environmental factors such as ultraviolet rays, ozone, and high temperature during long-term use. In contrast, traditional sealing materials such as natural rubber and styrene-butadiene rubber are prone to aging when exposed to harsh environments for a long time, resulting in a decrease in sealing performance. Therefore, it has obvious advantages in weather resistance and can ensure long-term use effects.
Secondly, from the perspective of sealing performance, it has good sealing performance. It also has a low compression permanent deformation rate, which means that when subjected to external forces, it can maintain good elasticity, thereby effectively preventing the leakage of media such as gas and liquid. In addition, it also has high tensile strength and tear resistance, and can maintain stable sealing performance under high pressure. At the same time, the surface is smooth, and the friction between it and the sealed object is small, which is conducive to improving the sealing effect.

In addition to the above two main advantages, it also has some other advantages. For example, it has good chemical corrosion resistance and can resist the erosion of various chemical substances, and is suitable for various harsh working environments. In addition, it also has good low temperature resistance and can maintain good flexibility and sealing performance at low temperatures, which is suitable for use in cold areas.
In summary, EPDM sealing gaskets have significant advantages in weather resistance and sealing performance. Its excellent weather resistance ensures long-term use, and its good sealing performance ensures effective sealing effect. Therefore, it has been widely used in construction, automobiles, electrical appliances and other fields.
