Key Technical Advantages
1. Precision Thickness Control
With nominal thickness ranging from 0.05mm (2mil) to 0.76mm (30mil), Wet-laid Aramid Nonwoven offers 9 standardized grades to meet diverse industrial requirements. The material maintains dimensional consistency with maximum 3.5% shrinkage at 300℃ (per IEC60819-2:2002), ensuring reliability in high-temperature environments.
2. Superior Tensile Performance
Tested under GB/T12914-2008 standards:
- MD tensile strength scales from 41N/cm (2mil) to 650N/cm (30mil)
- CD tensile strength progresses from 17N/cm to 450N/cm
This bidirectional reinforcement makes Wet-laid Aramid Nonwoven ideal for load-bearing composites.
3. Optimized Weight-Density Ratio
Achieving 0.79-1.0g/cc density with basis weights from 41.5g/m² to 710g/m² (GB/T451.2-2002), the material provides exceptional strength-to-weight characteristics.
