Method for removing the odor of silicone products

The key to truly removing the odor of silicone products lies in the selection of silicone raw materials, vulcanization systems, and processes.

1. In terms of silicone rubber raw materials and production processing: Often, some silicone rubber product manufacturers add a certain proportion of recycled rubber to reduce costs, while also adding a certain proportion of polluting operating oil; However, these can only be achieved by using environmentally friendly and odorless operating oils that inhibit and degrade polluting volatile compounds in rubber recycled materials, and the cost will not be cheap. So to fundamentally solve the odor of silicone products, we need to choose from the raw materials and production processes of silicone. For example, choose high flash point and odorless oil; Do not add recycled adhesive; Do not use accelerator CBS; No need for DCP, etc. Recommendation: Silicone foam raw material

2. Vulcanization system and process: Silicone is a gas-phase adhesive, compounded with odorless vulcanizing agent. After secondary vulcanization, the silicone is formed (the secondary vulcanization time is recommended to be greater than 4 hours, the temperature is around 200 degrees Celsius, and it is a vacuum oven)

This helps to ensure that any remaining odor from the silicone raw materials is eliminated. Additionally, proper curing and post-curing processes should be followed to ensure complete removal of any remaining odors. It is also important to note that the vulcanization system and process should be designed to minimize the generation of volatile compounds, which can contribute to the odor of silicone products. Recommendation: Extended vulcanization time and temperature, vacuum oven.

By carefully selecting silicone raw materials, using environmentally friendly operating oils, and following appropriate vulcanization systems and processes, the odor of silicone products can be effectively removed.
