Artificial stone silicone mold is the main product of our factory. Due to the particularity of the production materials of artificial stone, which is required to have different heat resistance, expansion resistance, hardness, acid and alkali resistance and tear resistance than general resin mold silicone rubber, so in order to adapt to the special requirements of artificial stone molds suggest that they must not be mixed.
Artificial stone silicone mold features:
1. Various designs and beautiful surface textures are molded directly from the original stone samples. The textures and colors are natural and the colors are unified;
2. Good wear resistance;
3. High strength and zero drying shrinkage; low drying shrinkage (less than 0.5mm/m), no cracking;
4. Good freeze-thaw resistance, the compressive strength is still as high as 10.7Mpa after 15 freeze-thaw cycles at -20°C, fully able to cope with various complex outdoor environments in the north and south;
5. Low water absorption, can be directly used for exterior walls;
6. No radioactive substances, environmental protection and no radiation.
How to distinguish the quality of silicone mold:
- The brightness is good, and the purity of such silica gel is high;
- The same weight, the larger the volume, the better;
- After purchasing for a certain period of time, the silica gel has layers, the top looks like oil, and the bottom is Powder, such mold silica gel is inferior.
