10 Shore A Food Grade Platinum Cure Liquid Silicone Rubber 1:1 Mix Ratio Low Shrinkage for Candle Mold Wholesale
Food Grade Platinum Cure Liquid Silicone Rubber E610 – 10 Shore A
Hanast E610 Platinum Series is a food grade RTV2 platinum-cure liquid silicone rubber specifically engineered for high-precision candle mold making and food-safe casting applications. With 10 Shore A hardness and superior tear resistance (13 kN/m), this silicone delivers exceptional mold life and intricate detail reproduction across hundreds of casting cycles.
Key Features
- FDA Food Grade Certified – Complies with FDA 21 CFR 177.2600 and LFGB standards, safe for chocolate molds, candy casting, baking molds, and candle making
- Ultra-Low Shrinkage (≤ 0.1%) – Ensures dimensional accuracy for complex mold geometries and high-precision castings
- High Tear Strength (13±2 kN/m) – Extended mold service life, resists tearing during demolding of intricate candle and resin shapes
- 1:1 Mix Ratio by Weight – Simple, foolproof mixing eliminates ratio errors in production environments
- Room Temperature Cure – Cures at 25°C within 4 hours; can be accelerated to 20 minutes at 80-100°C for rapid prototyping
- Non-Toxic & Odorless – No harmful byproducts during curing, safe for continuous factory use
- Translucent Finish – Allows visual inspection of mixed components before pouring
