In the sales process of silica gel raw materials, some friends who make silica gel products will encounter problems such as peculiar smell on the surface of the products during production, and many friends will think that the quality of silica gel raw materials is not up to standard.

In fact, is there a problem with the raw materials when the silicone products have peculiar smell on the surface? Of course not. Silica gel raw material is a new type of environmental protection material with non-toxic, tasteless, high temperature resistance, chemical stability and other characteristics. If it is produced according to the standard formula, this phenomenon will not occur. Therefore, we should check the production process if there is odor on the surface of silicone products. So how can we solve the problem of odor on the surface of silicone products?

1. After secondary vulcanization, put the silicone products into the oven and bake them at 200 ℃ for 2 hours to reduce the odor of silicone products;
2. The silicone products can also be effectively removed by boiling them in boiling water for more than 2 hours;
3. The odorless curing agent or platinum curing agent is used when mixing silicone rubber raw materials, and the surface of the silicone products produced is odorless.
