Product details

The EPS Component Molding industry demands mold-making materials that deliver exceptional precision, reliability, and cost-efficiency. Hong Ye Silicone's addition curing silicone rubber (Model HY-E620) has been specifically formulated to excel in EPS & foam decoration applications.

Based on advanced platinum-catalyzed technology, this liquid silicone rubber delivers:

Near-zero shrinkage (<0.1%)

Outstanding tear resistance (20 kN/m)

Food-safe curing — zero byproducts, zero odor

20 Shore A hardness — optimal balance between flexibility for easy demolding and rigidity for dimensional stability. Viscosity 16000-20000 cps ensures excellent flow and detail capture.

【Key Features】

✅ Platinum Catalyst System — no byproducts, <0.1% shrinkage, no odor, food & skin safe
✅ High Tear Strength (20 kN/m) — mold edges resist splitting, longer mold life
✅ Excellent Flow & Detail Reproduction — self-leveling, captures fine textures
✅ Temperature Stability (-60°C to 200°C) — reliable in any environment
✅ Flexible Mixing (1:1 or 10:1) — 35-50 min pot life, workflow control
✅ Food-Grade Certified — FDA, REACH, RoHS compliant
✅ Extended Mold Life (800-1000+ casts)
✅ Chemical Resistance — compatible with gypsum, cement, GRC, PU foam, epoxy, wax, concrete
