Product Usage：Specifically designed for chocolate molds cake pans and ice cube trays. Compatible with gypsum cement GRC polyurethane foam epoxy resin polyester resin wax concrete and low-melt alloys.

Shenzhen Hong Ye Jie's HY-E635 addition curing silicone is engineered for

Silicone Kitchenware Mold Production. This platinum-catalyzed liquid silicone delivers near-zero shrinkage, outstanding tear resistance, and food-safe curing.

Core Performance Features

· 1. Near-Zero Shrinkage (<0.1%) — Faithful detail reproduction, no drift between runs.
· 2. Tear Strength (23-29 kN/m) — Edges and thin sections resist splitting; longer mold life.
· 3. Tensile (5.2-6.8 MPa) and Elongation (380-440%) — Handles complex geometries without tearing.
· 4. Viscosity (22000-26000 cps) — Excellent flow for fine textures, self-leveling.
· 5. Pot Life (32-65 min) — Adjustable via 1:1 (longer) or 10:1 (faster) ratio.
· 6. Food-Grade & Skin-Safe — FDA, REACH, RoHS certified; no toxic byproducts.
