Platinum Silicone Rubber - Mold Star 15 Slow (priced per gram) – Jacobs Hall Material Store

A tear-resistant silicone used both for mold-making and soft product development. A durometer rating of 15A places the flexibility of this material at around rubber-band-level softness, making it good for repeated casting of rigid parts, soft enclosures for electronics, small toys, prosthetics, and much more. About: Mold Star™ rubbers are easy to use platinum silicones which are mixed 1A:1B by volume (no weighing scale necessary). Mold Star™ silicones feature relatively low viscosities and vacuum degassing is not required for most applications. The pot life of Mold Star™ 15 SLOW is 50 minutes and cure time is 4 hours at room temperature. Mold Star™ silicones cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage. Molds made with Mold Star™ will last a long time in your mold library and are good for casting wax, gypsum, resins, concrete and other materials. Cured Mold Star™rubber is heat resistant up to 450°F
