Professional Medical Devices Mold Silicone HY-E635 - 35A Near-Zero Shrinkage

Engineered for Medical Devices, HY-E635 combines 35A Shore A hardness with balanced flow. Platinum catalyst ensures clean, predictable curing with no toxic byproducts.

Core Performance Features

• 1. Near-Zero Shrinkage (<0.1%) — Parts require zero rework for fit.
• 2. Outstanding Tear Strength (23-29 kN/m) — Molds withstand long production runs.
• 3. High Tensile (5.2-6.8 MPa) and Elongation (380-440%) — Stretches over undercuts and returns without deformation.
• 4. Optimal Viscosity (22000-26000 cps) — Balances detail capture with body.
• 5. Flexible Working Time (32-65 min at 25°C) — Ample time for multi-piece assemblies.
• 6. Food-Grade & Skin-Safe — Low VOC, no harsh fumes, FDA certified.
