The yellowing and discoloration of silicone products is a phenomenon that many consumers are familiar with. Do you think that yellowing of silicone products is a normal phenomenon? Or is there a slight concern for why it appears yellow?

Why the yellowing phenomenon occurs in silicone rubber products. In fact, the yellowing of silicone rubber is not its essence. The silicone rubber raw collagen material is divided into dozens of millions of molecular crystals, and different ingredients are added to it. The components can be changed at will to change its composition, so even if hundreds of thousands of molecular chains are not subject to the compounding reaction, there will be yellowing, but it is limited and blocked by the outside world, such as vulcanizing agents, raw materials, anti-yellowing agents and so on!

When it comes to vulcanizing agents, many silicone rubber products manufacturers use ordinary vulcanizing agents, and many products are applicable. However, when it is used as a highly transparent or translucent product, white color will often cause yellowing, so many silicones. Manufacturers will choose anti-yellowing vulcanizing agents and add anti-yellowing agents for high-transmission semi-transparent products without discoloration, which can ensure that high-temperature vulcanization produces secondary odor vulcanization without any color change, and the product does not change color for a long time!

In addition, there are certain factors in the raw materials. Generally, the raw materials of silica gel products are reinforced with white carbon black as the main body. The dosage of white carbon black is lower in material cost and the performance has different adjustments. Therefore, while improving other properties, the anti-yellow effect is affected and changed, so as the nature of the material changes, it is subject to more changes, which affects its quality!

On the other hand, the silicone protective sleeve is not prepaid during use. The ordinary precipitation method silicone rubber has yellowing, so the transparent silicone products will have some yellowing effects. It is recommended not to expose to the sun for a long time, contact with liquid, etc. factor!
