Product Description
In 1998, the European Union identified cobalt chloride as a class II carcinogen, blue gum containing cobalt chloride has been banned in Europe and the United States and phased out, in order to meet the needs of the market, the development of cobalt-free environmental color-changing silica gel.
The research and development of the product is based on blue rubber color-changing silica gel, which is made of orange color-changing silica gel by dyeing the inorganic salt mixture. It adopts a new non-toxic compound dyeing agent, which fundamentally eliminates the pollution caused by dyeing agent and color-changing agent to the environment. The product has become a new generation of environmental protection products with its original technological conditions and good adsorption properties.
