Addition Curing Silicone HY-E625 for Roman Column Mold Making

Product No：FW-PROD-001
Brand：hong ye jie
Product Usage：Tired of molds that shrink crack or lose detail after just a few casts? Shenzhen Hong Ye Jie Technology's HY-E625 addition curing silicone rubber is engineered for Roman Column Mold Making. This platinum-catalyzed liquid silicone rubber delivers near-zero shrinkage outstanding tear resistance and food-safe curing — properties that set it apart from conventional condensation-cure systems.

Core Performance Features
  1. Near-Zero Shrinkage (<0.1%) — Every detail from your master pattern is faithfully reproduced in every cast. No dimensional drift between early and late production runs.
  1. Outstanding Tear Strength (20-25 kN/m) — Mold edges, thin sections, and intricate details resist splitting during demolding. Translates directly to longer mold life.
  1. High Tensile Strength (4.5-6.0 MPa) and Elongation (380-480%) — Handles complex geometries and deep undercuts without tearing.
  1. Optimal Viscosity (18000-22000 cps) — Excellent flow properties capture fine surface textures. Self-leveling characteristics reduce air entrapment.
  1. Flexible Working Time (40-80 minutes) — Adjustable through mixing ratio selection (1:1 for longer, 10:1 for faster).
  1. Food-Grade & Skin-Safe Certified — FDA, REACH, and RoHS certified. No toxic byproducts.
