Hello everyone, do you know about rubber products? Let me explain it to you.

The first design factor to consider is: what substances will the seal come into contact with in the system? In addition to paying attention to whether the seal material can withstand the sealed fluid, such as air, water, oil, steam, fertilizer, etc., you should also pay attention to the metal or plastic parts that come into contact with the seal. For example, if an inappropriate rubber part and polycarbonate plastic are placed together for a long time, some components in the rubber part will slowly penetrate into the contact surface of the two, causing the surface of the polycarbonate plastic to crack.

Secondly, even if the rubber seal is only in direct contact with drinking water, the residual disinfectant in the water is also a factor to be considered. That is, what is used to disinfect the drinking water that comes into contact with the rubber part. The disinfection methods in each country and region in the world are different. The main methods are chlorination disinfection and chloramine disinfection. Studies have shown that these disinfectants remaining in the water will react chemically with the rubber parts, causing the rubber parts to swell and deform, or even decompose, thereby affecting the sealing function and life of the rubber parts.
