LSR
LSR (Liquid Silicone Rubber)
Injection-moldable silicone material for stable, precise, and repeatable small elastomer components.
Answer-First Summary
- Temperature Range: -60 C to +230 C, compound-dependent
- Process Profile: Liquid injection molding for tight-feature repeatability
- Engineering Role: Precision silicone route when conventional compression molding is less efficient
Good Fit
Best fit for precision geometries, high-repeatability molding, and clean-process elastomer parts.
Typical Application Windows
Precision silicone seals
Small clean-process gaskets
High-repeatability molded components
