What is the reason why silicone sealing rings do not fade?

A friend recently asked, "Why don‘t silicone seals fade?" In fact, the reason why silicone seals don‘t fade is mainly based on the production process of silicone products and the stability of silicone itself. Below, the editor will explain in detail for everyone.

Firstly, silicone sealing rings are made through vulcanization molding technology. During the manufacturing process, silicone raw materials are chopped or ground into powder, and then mixed with additives and pigments to form a paste like material. The pigments here, also known as colorants, will be evenly added to the silicone gel to ensure uniform color distribution during the subsequent molding process.

Secondly, silicone has excellent stability. Silicone sealing rings can be used for a long time in the temperature range of -60 degrees to+200 degrees, which means that they will not undergo significant physical or chemical changes, including discoloration, due to temperature changes. In addition, silicone also has advantages such as corona resistance, arc resistance, high and low temperature resistance, and good aging resistance, which provide a guarantee that it is not easy to fade.

Finally, the color of the silicone sealing ring is formed by adding colorants to the silicone raw material, mixing them evenly, and then molding them on the machine. Due to the thorough mixing of color with silicone raw materials during the production process, it will not easily fade due to external factors.

That‘s why the reason why the editor said that silicone sealing rings do not fade is mainly based on the production process of silicone products and the stability of silicone itself.
