How to prevent fading of rubber products

Rubber products are prone to yellowing during use and storage, which can affect their appearance and quality, leading to various economic disputes and irreversible losses. Rubber has a certain service life, and over time, it will age

Purchase rubber seals - O-ring seals

After rubber products are produced and formed, there will be product burrs on the products. The rough edge treatment of rubber products has high requirements for product appearance on the one hand, and is also inevitably related to product prices on the other hand. The processing of rough edges in general rubber products also incurs production costs for manufacturers. Therefore, while ensuring product quality in the process of processing rough edges, manufacturers pay more attention to the efficiency of processing rough edges in rubber products.

Ozone aging and maintenance of rubber products

When ozone comes into contact with rubber products, it first undergoes an addition reaction with active double bonds, generating molecular ozonates. 1 molecular ozonates are very unstable and quickly decompose to form carbonyls 2 and zwitterions. In most cases, zwitterions and carbonyls will recombine to form odorous oxides ©， Amphoteric ions can also polymerize to form peroxides © Or high peroxide ©， In addition, when active solvents such as methanol are present, zwitterions will react with them to form methoxy hydrogen peroxide. The activation energy of the reaction between ozone and unsaturated rubber is very low, and the reaction is very easy to proceed. The reaction is until the double bonds of the rubber are completely consumed. At this time, a silver white film that loses elasticity is formed on the surface of the rubber. As long as there is no external force to crack the film, the rubber will no longer continue to undergo ozone oxidation. If the rubber that has already undergone ozone oxidation is stretched or subjected to dynamic deformation, the generated ozone oxidation film will crack, exposing the new rubber surface and reacting with ozone, causing the cracks to continue to grow. Saturated rubber does not contain double bonds, and although it can react with ozone, the reaction proceeds slowly and is not prone to cracking.
