Dimensional Precision & Stability
Enables precise micro-feature replication—ideal for complex geometries and tight-tolerance parts.
Typical shrinkage rates are ≤ 2%, ensuring excellent dimensional repeatability during mass production.
Maintains shape integrity even under thermal cycling, making it suitable for precision medical devices, optical components, and high-tolerance seals.
Chemical Resistance
LSR offers excellent resistance to water, oils, acids, alkalis, and solvents, due to its stable silicone backbone. It remains chemically stable from –60°C to +250°C, providing long-term performance in aggressive environments.
Food-Grade & Medical-Grade Compliance
Certified for critical applications requiring safety and purity:
FDA 21 CFR 177.2600 – Food contact safety
ISO 10993 – Biocompatibility for medical use
Our Advantages
Wide Hardness Range
Shore hardness from 10A to 80A, enabling customization from ultra-soft elastomers to high-hardness components for diverse applications.
Sustainable Manufacturing
Liquid injection molding technology minimizes material waste, enhances utilization, and aligns with low-carbon production principles.
