Visicryl 7290 Tds [2024]

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 |

Key Take‑aways: The combination of polycarbonate toughness and acrylic stiffness yields a material that resists cracking under impact while maintaining a rigid, dimensionally stable platform across a wide temperature window. | Optical Parameter | Value (Typical) | Test Standard | |-------------------|----------------|----------------| | Visible Light Transmission (400‑700 nm) | ≥92 % (at 2 mm) | ASTM D1746 | | Haze (at 2 mm) | ≤2 % | ASTM D1003 | | Refractive Index (n₍D₎) | 1.495 | Manufacturer measurement | | Yellowing Index (after 100 h UV‑A exposure) | ≤1.0 | ASTM G155 | | Gloss (60° geometry) | 85 GU | ASTM D523 | visicryl 7290 tds
