Gypsum is widely used in the field of architectural decoration. HY-625 mold silicone rubber is very suitable for gypsum moldings, such as gypsum decoration, building products, furniture decoration, gypsum crafts, plaster statues and other gypsum products. Of course, the hardness of HY-625 is 25 shore A hardness, which is more suitable for products with more fine and simple lines; if the pattern is very fine, you can choose the soft HY-620; if the pattern is very simple, the harder HY-630 may be more suitable.   HONG YE HY-625, as a molding silicone rubber which is very suitable for gypsum product molding, has the following advantages: 1. Good elasticity, easy to demould, and will not damage the product when demoulding 2. Easy adjustment of fluidity: low viscosity, good fluidity and easy foam discharge during mold pouring; high viscosity can be adjusted to facilitate mold brushing. 3. High and low temperature resistance, acid and alkali resistance, aging resistance, no expansion, good tensile strength, high tear strength, no deformation, which is conducive to the repeated use of the mold, so that the mold turnover times are high and even up to thousands of times. 4. The shrinkage rate is less than 2 / 1000, and the glass fiber cloth has better anti shrinkage ability.
