Visicryl 7290 Tds May 2026

For optimal adhesion, a light corona or plasma treatment (e.g., 30 W, 30 s) markedly improves surface energy from ~40 mN m⁻¹ to >55 mN m⁻¹, facilitating strong bonds with both polar and non‑polar adhesives.

*Parameters are typical starting points; fine‑tuning may be required based on sheet thickness, equipment, and desired surface finish. visicryl 7290 tds

The blend is engineered through a twin‑screw extrusion process that ensures intimate molecular intermixing, resulting in a homogeneous, isotropic sheet with minimal phase separation. | Property | Typical Value (±5 %) | Test Standard | |----------|----------------------|----------------| | Density (at 23 °C) | 1.20 g cm⁻³ | ASTM D792 | | Tensile Strength (MD/TD) | 70 MPa / 65 MPa | ASTM D638 | | Elongation at Break (MD/TD) | 120 % / 115 % | ASTM D638 | | Flexural Modulus (25 mm) | 2.5 GPa | ASTM D790 | | Impact Strength (Izod, notched) | 600 J m⁻¹ | ASTM D256 | | Heat Deflection Temperature (HDT, 0.455 MPa) | 115 °C | ASTM D648 | | Service Temperature Range | –40 °C to +120 °C (continuous) | Manufacturer data | | Coefficient of Thermal Expansion (CTE) | 70 × 10⁻⁶ °C⁻¹ (in‑plane) | ASTM D696 | | Water Absorption (24 h, 23 °C) | ≤0.2 % | ASTM D570 | For optimal adhesion, a light corona or plasma treatment (e
