Generally, the raw materials needed to make silicone steamer mats are silicone rubber compound and peroxide vulcanizing agent, both of which can generally pass the six ROHS tests (heavy metal tests) of the European Union, and it is generally believed that silicone rubber will not be toxic as long as it is not made of recycled materials.
Generally, silica gel steamer mats are made by calendering or molding, and no toxic substances are added in the process, that is, they are non-toxic in the production process. Therefore, considering the raw materials and technology of the whole silica gel steamer pad, it can be considered that the silica gel steamer pad is non-toxic.
The silica gel material of steamer pad is generally food grade silica gel, which can be divided into industrial grade, food grade and reclaimed rubber. Consumers should not buy floor mats that are too cheap.
