1:1 Mix Ratio High Tear Strength Platinum Cure Silicone Rubber
This premium addition cure (platinum catalyzed) RTV silicone rubber features the industry's simplest 1:1 equal-part mixing ratio and exceptional 15-17 N/mm high tear strength, making it the ideal choice for professional mold making applications that demand both ease of use and durability.
Key Features
Effortless 1:1 Mix Ratio — Simple equal-part A:B mixing eliminates complex calculations and reduces operator error, ensuring consistent batch results every time
Exceptional Tear Resistance 15-17 N/mm — Industry-leading tear strength extends mold service life by 2-3x compared to standard silicones, delivering more demolding cycles
Customizable Hardness 10-30 Shore A — Adjustable hardness range allows tailoring from ultra-soft to semi-rigid for different mold applications
High Transparency — Translucent formulation enables easy visual monitoring of mold quality and allows color pigmentation per customer requirements
Superior Tensile Strength 3.8-4.0 Mpa — High tensile strength prevents mold tearing during demolding of complex geometries and undercuts
Excellent Release Properties — Self-releasing surface minimizes the need for additional mold release agents, reducing production steps and costs
Extended Working Time 30-40 min — Generous pot life provides ample time for mixing, degassing, and pouring into complex mold cavities
Typical Applications
Resin Mold Making — Ideal for crafting detailed resin molds including jewelry, coasters, and decorative items
Cake & Food Molds — Perfect for baking and confectionery molds when food-grade certification is verified
Candle & Soap Molds — Excellent reproduction of fine surface details for artisan candle and soap making
Gypsum & Plaster Molds — Durable molds for architectural decoration and ornamental casting
Rapid Prototyping — Quick mold production for product development and short-run manufacturing
