LSR is a two-part (A+B) platinum-cured silicone elastomer that cures into a flexible, rubber-like material when heated. Its liquid form allows for injection molding, making it ideal for mass-producing intricate, high-performance components with tight tolerances.
| Property | Benefits |
|---|---|
| High Temperature Resistance | Stable from -40°C to 250°C, suitable for sterilization (autoclaving) and extreme environments. |
| Biocompatibility | FDA, ISO 10993, and LFGB certified—safe for medical implants, baby products, and food contact. |
| Soft & Elastic | Adjustable hardness (Shore A 10–80), from ultra-soft gels to firm rubber. |
| Chemical & UV Resistance | Resists oils, acids, ozone, and UV degradation, ensuring long-term durability. |
| Excellent Electrical Insulation | Used in waterproof electronics and high-voltage applications. |
| High Flowability | Fills intricate molds, enabling microfluidic chips and precision seals. |
| Feature | Liquid Silicone Rubber (LSR) | Solid Silicone Rubber (HCR) |
|---|---|---|
| Form | Liquid (2-part system) | Solid (sheets or pellets) |
| Processing | Injection molding (fast curing) | Compression/transfer molding (slower) |
| Precision | High (complex geometries, thin walls) | Limited (simpler shapes) |
| Production Speed | Seconds to minutes | Minutes to hours |
| Cost Efficiency | High for mass production | Better for low-volume runs |
