Stainless Steel Handmade Sink Manufacturers Share Why Transparent Silicone Products Will Yellow
Today, Stainless Steel Handmade Sink Manufacturers came to share why transparent silicone products are yellowing?
1. Vulcanizing agent
1. The performance of vulcanizing agent is divided into common type and anti-yellow property. Its application range has the following two aspects:
2. Ordinary non-anti-yellow vulcanizing agent, used in some non-exposed silicone products that can be used for darker colors or less demanding colors.
3. Anti-yellow vulcanizing agent is applied to products that need to be exposed, lighter in color and more vivid, and have higher color requirements.
2. Process: When the transparent silicone product is formed, the color of the transparent silica gel product becomes yellow after molding. There are mainly problems:
1. The mold temperature is too high
2. The curing time is too long,
3. After the second vulcanization, the quality of the raw material itself is too bad. Sometimes we add anti-yellow vulcanizing agent to the rubber compound, but the transparent silica gel product still looks yellowish after molding, which may be the anti-yellow material. The ability is too bad, the raw material for the raw material is too poor to resist yellowing is the direct refueling.
