The detailed annotation of mould making silicon ru...

Mould making silicon rubber is suitable for industries such as toys, gifts, decoration, plate engrave, human replica, art crafts, resin crafts, poly resin crafts, unsaturated resin crafts, candle crafts, plastic crafts, stationeries, plaster crafts and Buddhist statue crafts. 　　According to the different materials,two series of mould making silicon rubber are divided, which are HY-6 and HY-7. 　　a. HY-6 Series includes model codes of HY-620, HY-640, HY-630, HY-635 with the hardness of 18-22 shore A, 38-42 shore A, 28-32 shore A and 33-37 shore A respectively. 　　HY-620 and HY-640 are particularly suitable for pouring mould. 　　HY-620 is for small crafts mould making, while HY-640 is for large crafts mould making. Common features of HY-620 and HY-640: light viscosity, pourable effort, good fluidity, easy-operation, good tension and high tear strength. 　　HY-630 and HY-635 are particularly suitable for brushing mould making. 　　Common features of HY-630 and HY-635: moderate viscosity,easy-operation.Agents are available if requested.It won't affect the quality of silicone rubber but to make the operation much easier. 　　b. HY-7 Series includes model codes of HY-720, HY-730, HY-735 with the hardness of 18-22 shore A, 28-32 shore A and 33-37 shore A respectively. 　　HY-720 is a kind of soft silicon rubber and suitable for pouring mould making of small crafts. 　　HY-730 with moderate viscosity is suitable for pouring mould and collapsible mould making of crafts in medium size. 　　HY-735 with high hardness is suitable for to collapsible mould making of crafts in large size. 　　Features of mould making silicone rubber: 　　1. Good characteristics of easy-operation 　　2. Light viscosity and good flowability 　　3. Low shrinkage 　　4. Favorable tension 　　5. No deformation 　　6. Favorable hardness 　　7. High temperature resistance, acid and alkali-resistance and ageing resistance 　　Limitations: 　　a.When the hardness of silicon rubber is lower than 15 shore A, the tension, the tear strength, the ageing resistance, acid and alkali-resistance of silicon rubber will reduce respectively. 　　b.When the hardness of silicon rubber is higher than 50 shore A, the tension and the tear strength of silicon rubber will reduce, and the solidified silicon mold will be easily broken. 　　Shenzhen Hongye Jie Silicone Factory professional development, increase production of liquid silicone molding,liquid silicone molding plus,plus liquid silicone rubber molding silicone products,welcome customers and dealers to negotiate,expert advice hotline:86-0755-89311348,you can also e-mail us info@szrl.net.
