1. The LSR Revolution: Beyond Conventional Rubber
Our Liquid Silicone Rubber redefines material performance through platinum-catalyzed cross-linking. Unlike conventional rubbers:
- Cures in seconds at 150-200°C
- Achieves >99.7% mold fill accuracy
- Maintains consistent viscosity (±3%) during processing
Automotive Tier 1 suppliers report 40% reduced cycle times vs. TPV.
2. Unmatched Environmental Resistance: Our LSR Formulation
Proprietary LSR chemistry delivers extreme performance:
| Condition | Performance | Test Standard |
|---|---|---|
| Temperature | -60°C to 250°C | ASTM D1329 |
| Chemical | Resists IPM, ethanol, bleach | ISO 1817 |
| UV/Ozone | 0% degradation @ 3000hr | ASTM G154 |
| Electric vehicle seals using our LSR withstand battery acid exposure at 90°C. |
3. Medical-Grade Excellence: Certified Biocompatibility
Our medical LSR grades meet critical certifications:
- ISO 10993 (Cytotoxicity, Sensitization, Irritation)
- USP Class VI
- FDA 21 CFR 177.2600
Features: - Zero extractables (<0.1% per ISO 10993-12)
- Autoclavable (134°C/20min cycles)
- Radiolucent for imaging
Used in 80% of top-10 medtech neonatal devices.
4. Sustainable Manufacturing: Efficiency of Our LSR Process
LSR production advantages:
| Conventional Rubber | Our LSR | |
|---|---|---|
| Cure Time | 8-15 minutes | 15-90 seconds |
| Scrap Rate | 12-18% | <3% |
| Energy Use | 35 kWh/kg | 18 kWh/kg |
| Patented cold-runner systems achieve 99% material utilization. |
5. Growth Applications: Where Our LSR Leads Innovation
High-growth sectors powered by our LSR:
- EV Batteries: Flame-retardant seals (UL94 V-0)
- Wearables: Skin-adhesive biocompatible grades
- Infant Care: BPA-free nipple formulations
Case Study: Leading breast pump manufacturer reduced particulate matter by 92% switching to our LSR.
6. Technical Specifications: LSR Performance Data
Standard LSR properties:
| Property | Value | Test Method |
