Key Characteristics of Liquid Silicone Rubber (Why It Is Suitable for Photopolymer Resin Molding)

1. High Fluidity
   Liquid in its uncured state, it quickly penetrates fine gaps of the master mold (such as textures and sharp corners below 0.1mm), ensuring 1:1 replication of details and avoiding "detail loss."

2. Elasticity and Demolding Performance
   After curing, Shore A hardness typically ranges from 10 to 35 degrees (primarily soft), offering excellent elasticity and high flexibility. Even if the master mold has slight undercut structures, it allows for easy demolding, reducing damage to the mold or replicated parts.

3. Chemical Stability
   High compatibility with photopolymer resin (solvent-free types must be selected), ensuring no corrosion or dissolution of the master mold (some low-quality silicone rubbers contain solvents, which may cause swelling or deformation of the photopolymer resin master mold surface). It also resists acids, alkalis, and aging, extending the mold's service life.

4. Curing Controllability
   Mostly two-component (Component A: base胶; Component B: curing agent). Curing speed can be adjusted by varying the ratio and temperature (room temperature curing takes 2-24 hours, while heat curing can shorten it to within 30 minutes), adapting to different production schedules.
