Industrial Grade Tin-Cure Liquid Silicone Rubber (LSR)
1. Industry-proven solutions for demanding applications
Our tin-catalyzed liquid silicone rubber (LSR) continues to be the first choice for industrial mold making,
providing the best balance of performance, cost-effectiveness and fast production for manufacturers worldwide.
Formulated for high-volume applications, the material excels in making durable molds for:
- Polyurethane/resin casting
- Low melting point metal alloys (e.g. tin, zinc)
- Concrete/gypsum precast
- Wax-based prototyping
2. Key Benefits:
- 30% faster cure compared to conventional tin-cure LSRs
- Enhanced tear strength (up to 40 kN/m) for complex geometries
3. Technical Advantages for Industrial Workflows
A. Precision and Durability
- Shrinkage as low as 0.2% – Maintains dimensional stability for close tolerance parts
- Shore A hardness range: 00-60 – From flexible wax patterns to rigid composite molds
- Operating range: -50°C to 250°C – Withstands repeated thermal cycling
B. Cost-effective Production
- 100:2 mix ratio – Reduces material waste compared to platinum-cure alternatives
- No post-cure required – Ready to use immediately after demoulding
- 300+ cycle life – Ideal for small batch production
C. Chemical compatibility
- Resistant to polyurethanes, epoxies and acidic concrete mixes
- Does not react with sulfur-based clays (common in foundry patterns)
4. Industrial applications
- Automotive: Gasket prototypes, interior molds
- Construction: Decorative concrete panel replication
- Aerospace: Composite layup tools for carbon fiber parts
- Art foundries: Investment casting wax patterns
