Gypsum mold making silicone rubber compound

Gypsum mold making silicone rubber compound with low viscosity, high strength and better mobility is applicable to making molds of large stone, gypsum and cement replication, and also especially suitable for the replication of original pattern which is sophisticated and complex.   Materials of gypsum mold making: When it comes to the materials of gypsum mold making, the majority of people believe that silicone rubber compound is the best choice. The gypsum mold silicone with the characteristics of no deformation, good tensile and tear effect, and resistance to high temperature of 160 ℃ or even higher can replicate and produce the gypsum products in large quantities. While, fiberglass plaster mold is mainly used to make relief or large pieces of plaster products, but is not suitable for making small pieces of plaster crafts. Silicone rubber compound is soft, so, it is necessary to make an outer mold using resin, plaster or fiberglass prevent the gypsum mold silicone from deforming. Plastic gypsum mold is mainly used for cartoon type and its' quality is low. So, no material has received more praise than silicone rubber compound.   Factors affecting the quality of gypsum mold making: There are many factors linked to the quality of gypsum mold making, such as dehydration methods and temperature, calcining time, granularity, water pH, mold species quality, quality of the release agent, casting process, and operating technology, and the external environment and so on. Of course, choosing the high quality raw material (silicone rubber compound) is the most important aspect.   Advantage of gypsum mold making silicone rubber compound: 1. Gypsum mold silicone has a high number of rolling over, and basically can reach thousands of times. 2. Silicone rubber compound is easy to operate, and you can take the methods of pouring way or brushing mould. 3. Different hardness of gypsum mold silicone can be for you to choose from. If you wanna to make molds for small plaster crafts, you can choose the silicone rubber compound of HY-620 and HY-718 with the hardness of 18-22 shore A, 16-20 shore A respectively. And the gypsum mold silicone of HY-640 and HY-738 with the hardness of 38-42 shore A, 35-40 shore A respectively is thebest fit for large gypsum, such as gypsum statue. 4. Gypsum mold silicone has better liquidity, lower linear shrinkage and low viscosity. 5. The silicone rubber compound can deep sulfide, the curing of which is from top to bottom, from the inside to the outside. The gypsum mold doesn't exist the phenomenon of sticky and degradation under the close condition or high temperature, because the gypsum mold silicone will not release low molecular in the process of curing.   There are strong evidences that Shenzhen Hong Ye Jie Technology Co., Ltd. is the global leading silicone rubber compound manufacturers.
