Two Part Platinum Cure Liquid Silicone Rubber 20 Shore A 1:1 Custom OEM for Food Grade Cake Molds
Two Part Platinum Cure Liquid Silicone Rubber (E620, 20 Shore A)
Hanast E620 Platinum Series is a two part food grade platinum cure liquid silicone rubber engineered for high-precision mold making and food-safe casting. Based on an addition-cure (platinum) system with a simple 1:1 mix ratio by weight, it delivers ultra-low shrinkage and a long working life for repeated casting cycles.
Key Features
- FDA & LFGB Food Grade – Complies with FDA 21 CFR 177.2600 and LFGB for food-contact molds (candle, chocolate, candy, baking, soap).
- Ultra-Low Shrinkage (≤ 0.1%) – Excellent dimensional accuracy for complex, high-precision mold geometries.
- High Tear Strength (13 ± 2 kN/m) – Extended mold service life and clean demolding.
- 1:1 Mix Ratio by Weight – Foolproof mixing, minimizing ratio errors in production.
- Room Temperature Cure – Cures at 25°C within 4 hours; heat-accelerated to 20 minutes at 80–100°C.
- Custom OEM Formulation – 0–60 Shore A hardness range (E600–E660 series) and tailored viscosity/pot life for OEM projects.
