Revolutionary Advantages of Liquid Silicone Rubber(LSR) in Medical Device Applications
Technological Breakthroughs and Clinical Value of Medical-Grade Materials
l. Exceptional Biocompatibility:
The Gold Standard for Safe Contact
– Certified to stringent standards including lSO10993/USP Class Vl
– Free of plasticizers, latex ,and animal-derived components
– Implant-grade formulations enable prolonged contact with tissues/body fluids (e.g ,pacemaker seals)
ll. Precision Micro-Molding Capabilities:
Transforming Complex Device Manufacturing
– Nano-scale flowability(viscosity <100 Pa·s) for filling microfluidic chip channels
– 0.1um surface smoothness inhibits bacterial growth (5x superior to metal instruments)
– Zero-flash molding eliminates secondary processing (single-step molding for catheters/
connectors)
Ill. Superior Environmental Resistance:
Ultimate Protection for Clinical Scenarios
| Performance Metric
| Medical Rubber | Medical LSR | Clinical Value |
| Heat Resistance
| ≤120°C
| 230°C
| Withstands 135°C autoclaving |
| Chemical Stability
| Moderate | Exceptional | Resists iodophor/ Alcohol corrosion |
| Compression Set (22h) | 15-25% | <3% | Ensures seal longevity |
IV. Smart Manufacturing Revolution:
From Lab to Mass Production
-72-hour rapid mold validation (supports minimally invasive device iteration)
-Automated cleanroom production (particle control to lS0 14644 Class 5)
-In-situ coloring for functional zoning (e.g., drug dosage indicators)
V. Innovative Applications
1. Minimally Invasive Interventions
-Catheter balloons (<5% compliance deviation)
-Ultrasound probe acoustic matching layers
2.Long-Term lmplantables
-Neural electrode coatings (10-year in vivo stability)
-Artificial corneal sealing
rings
3.Smart Medical Components
-Wearable biosensor substrates
-Surgical robot haptic feedback layers
