Q: How does the choice between solid silicone rubber and liquid silicone rubber (LSR) affect product performance and production cost?

A: Solid silicone rubber (HCR - High Consistency Rubber) and liquid silicone rubber (LSR) differ mainly in viscosity, processing methods, and application suitability.

Material Form: Solid silicone rubber comes in a gum-like form and is typically processed by compression or transfer molding. LSR is a two-part liquid material cured by injection molding.

Production Efficiency: LSR injection molding allows automated, high-speed production with minimal waste-ideal for high-volume precision parts like medical valves or baby nipples. In contrast, solid silicone compression molding is slower and more labor-intensive but cost-effective for low-volume or large-size components.

Performance & Tolerance: LSR provides better dimensional stability, clarity, and consistency, while solid silicone can achieve higher mechanical strength and tear resistance.

Cost Comparison: LSR raw materials are usually 10–20% more expensive, but overall production cost per part may be lower due to automation and shorter cycle times.

In summary, LSR suits mass production of precise, small parts, while solid silicone is better for customized or heavy-duty applications.
