HY-E628 Silicone for Film & Stage Props

For professionals who refuse to compromise on mold quality, the solution is clear.

Hong Ye Jie's HY-E628 sets the performance standard for addition-cure silicone in film & stage props. At 28A Shore A, it provides toughness and precision.

Core Performance Features

1. Near-Zero Shrinkage (<0.1%)

With linear shrinkage below 0.1%, this material holds tolerances that condensation silicones cannot match.

2. Outstanding Tear Strength (21-26 kN/m)

Thin mold edges, deep undercuts, and intricate details withstand demolding stress without splitting.

3. High Tensile (4.8-6.2 MPa) and Elongation (390-470%)

Structural robustness comes from optimized crosslink density; the material flexes but does not permanently deform.

4. Optimal Viscosity (19000-23000 cps)

Vacuum degassing is enhanced by flow characteristics; bubbles rise and escape efficiently before set.

5. Flexible Working Time (38-75 min at 25 °C)

Working time can be fine-tuned to ambient temperature and project scale.

6. Food-Grade and Skin-Safe Certified

The comprehensive certification package simplifies compliance documentation for regulated markets.

Application Focus: Film & Stage Props

The HY-E628 is formulated for film & stage props. At 28A Shore A, it balances demolding flexibility with shape retention. Typical projects include theatrical set pieces, movie prop replicas, and animatronic skins.

Practical tips: For on-set rapid prototyping, use heat acceleration at 60 °C. Consider pigmenting silicone for color-matching.

Compatible casting materials:

• polyurethane foam
• epoxy resin
• plaster and gypsum
• latex
• polyester resin

The inert cured silicone does not react with these materials.
