Product advantage
Quality assurance of raw materials
Our silica gel is made of imported raw materials(include Dow Corning, Wacker, and Shinetsu cooperation partner), and the produced silica gel has a bright feeling.
However, the fake colloids on the market are faintly covered with particulate impurities, and the grinding process is not carried out during the production process or impurities are present in the raw materials.
The delicate degree of silicone rubber
Good quality colloids are fine and free of impurities. They are rubbed with fingers and rubbed against the silica gel. There are no granules or floating objects.
Good fluidity and good leveling
The better the fluidity of the liquid silicone gel, the less likely it is to generate bubbles during the filling operation, so the quality of the silicone mold or product made is better and more durable.
