Free Sample Food Grade Two-Part Liquid Silicone Mold Soft and Flexible Flame Retardant for Cake and Soap Molding

HY-E625 Silicone Rubber | Mold Making Silicone​，

Product Description​

HY-E625 is a high-performance two-component platinum-curing/addition-cure silicone rubber, mainly categorized as liquid RTV2 silicone (3% shrinkage rate) with a translucent silicone rubber variant. This silicone RTV boasts excellent flowability and supports dual curing methods (room temperature vulcanization/RTV and heat-accelerated vulcanization), enabling it to retain superior softness, elasticity and stable physical properties during long-term use in extreme temperatures ranging from -65°C to 200°C. Adopting a non-toxic addition-cure system, it ensures a safe, controllable curing process free of harmful by-products. The translucent silicone rubber variant features a clear, pure texture and outstanding optical performance, maintaining high translucency without obvious yellowing after curing—making it ideal for applications demanding exceptional appearance transparency,

 all with a consistent 3% shrinkage rate.​
Wide Applications​

This liquid RTV2 silicone is well-suited for mass production molding across multiple industries, covering scenarios such as art crafts, furniture ornaments, architectural decorative elements, garden statues, shoe soles, tire prototypes, soap and candle making, jewelry casting, vacuum bagging processes, wind turbine blade manufacturing, ship/boat hull and aircraft hull mold production, FRP pipes/profiles, beacon lighthouse covers, military industry, and aviation & aerospace precision component molding. Both the translucent silicone rubber and standard silicone RTV variants of HY-E625

 offer strong compatibility with various casting materials, including resin, PU, PVC, polyester, gypsum/plaster, concrete, cement, stone, GRC/GFRC, wax, and jewelry alloy, with the 3% shrinkage rate ensuring dimensional stability.​
Core Features & Advantages​

•
Food Grade Certified (FDA) - Safe for food contact molding scenarios​
•
Controlled 3% Shrinkage Rate - Uniformly applied to translucent silicone rubber, liquid RTV2 silicone and silicone RTV, this rate strikes a perfect balance between molding precision and durability, avoiding embrittlement from zero-shrinkage formulas while ensuring consistent dimensional stability of finished products.​
•
Low Viscosity & Excellent Flow Leveling - The liquid RTV2 silicone features low viscosity for easy pouring and operation, effortlessly filling complex structures. It excels at capturing the finest details and delicate patterns of original models, paired with effective defoaming performance for smooth mold surfaces.​
•
Anti-deformation & High Tear/Tensile Strength - Maintains mold shape stability after multiple curing and demolding cycles, durable in use and extending mold service life​
•
Non-oily & Bubble-free - No oil seepage or pinholes on mold surface, avoiding contamination of workpieces and casting materials​
•
High Temperature Resistance - This silicone RTV maintains stable performance under alternating high and low temperatures, adapting seamlessly to diverse industrial

 working environments and extending mold service life.
