company news about What is a Flex Texture Sponge?

1. Material Composition

• Modified polyurethane foam matrix with controlled cross-linking density

• Cell structure: 30-50 μm open-cell configuration

• Resilience index: ≥85% recovery rate

• Liquid retention capacity: 25% enhancement vs conventional substrates

2. Surface Architecture
Dual-zone surface topology:

• Planar zone (Ra ≤0.8 μm): Precision transfer surface

• Contoured zone: Multi-scale pore structure (50-200 μm gradient)

• Surface energy: 35-40 mN/m for optimized release characteristics

3. Mechanical Properties

• Elastic modulus: 0.8-1.2 MPa (dry state)

• Wet state modulus: 0.3-0.6 MPa

• Compression set: ≤5% (per ASTM D395)

• Chemical resistance: Stable in pH 4-11 environments

4. Performance Metrics

• Transfer efficiency: 92% (ASTM D4261)

• Film thickness control: 15-50 μm range

• Compatibility: Universal for aqueous/oleous formulations

• Service life: 3-5× conventional alternatives
