Looking for a reliable mold making solution that delivers consistent quality?
Shenzhen Hong Ye Jie Technology's HY-E620 addition curing silicone rubber is engineered for Humanoid Robot Skin Fabrication. 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. Perfect for batch manufacturing where consistency matters.
2. Outstanding Tear Strength (18-25 kN/m)
Mold edges, thin sections, and intricate details resist splitting during demolding. Translates directly to longer mold life and lower per-unit mold costs.
3. High Tensile Strength (4.0-6.0 MPa) and Elongation (350-500%)
Maintains structural integrity even under demanding casting conditions. Handles complex geometries and deep undercuts without tearing.
4. Optimal Viscosity (16000-20000 cps)
Excellent flow properties capture fine surface textures and complex geometries. Self-leveling characteristics reduce air entrapment and minimize manual spreading.
5. Flexible Working Time (45-90 minutes pot life)
Ample time for careful pouring and positioning on large or complex molds. Adjustable through mixing ratio selection (1:1 for longer, 10:1 for faster).
6. Food-Grade & Skin-Safe Certified
Platinum catalyst system produces no toxic byproducts. Certified by FDA, REACH, and RoHS. Safe for food-contact and medical applications.

▎ Application Focus: Humanoid Robot Skin Fabrication
The HY-E620 is particularly well-suited for realistic silicone skin for humanoid robots and prosthetics. Whether you are producing small decorative pieces or large-scale production runs, this silicone delivers the reliability and performance your project demands.
Compatible Casting Materials: • Gypsum and plaster • Cement and GRC mixtures • Polyurethane foam • Epoxy resin and polyester resin • Wax and concrete • Low-melt alloys
The chemically inert cured silicone will not react with any of these materials, ensuring clean demolding and surface finish every time.
