Although silicone sealing strips and rubber sealing strips are common sealing materials, they have some differences in nature and use.

Although silicone sealing strips and rubber sealing strips are common sealing materials, they have some differences in nature and use.

First of all, the silicone sealing strip has high heat resistance and can withstand use in high temperature environments. This makes the silicone seal very suitable for some high temperature applications, such as water heaters, gas stoves, etc. In contrast, the heat resistance of rubber sealing strip is poor, and it is easy to harden and age in high temperature environment.

Secondly, the silicone sealing strip has good weather resistance and corrosion resistance, and can adapt to different climate and environmental conditions. This makes the silicone sealing strip commonly used for outdoor equipment and pipeline sealing. Rubber seals, on the other hand, are relatively brittle and susceptible to UV rays and chemicals, requiring additional protection when used outdoors.

In addition, the elasticity and sealing performance of the two are also different. The silicone sealing strip has good elasticity and can maintain the sealing effect under different temperatures and pressures, while the rubber sealing strip has poor elasticity and is easy to deform, requiring higher pressure to achieve effective sealing.

To sum up, there are obvious differences between silicone sealing strip and rubber sealing strip in terms of heat resistance, weather resistance, corrosion resistance and elasticity, so it is necessary to make a reasonable choice according to the specific application requirements.
