15 Shore A RTV-2 Silicone Rubber for Mold Making
Model: 717AB-F (15°) Hardness: 15±2 Shore A
717AB-F (15°) is a 1:1 platinum mold silicone with 15±2 Shore A hardness, designed for mold work that needs both flexibility and shape support. Compared with softer grades, it holds mold walls more steadily while still allowing clean release from detailed parts. Good fluidity helps capture patterns, relief lines and surface textures, while tear resistance improves mold durability during repeated use. Low odor and natural bubble release make the working process cleaner. This grade suits resin, gypsum, candle and craft molds that need balanced softness and practical support.
