Visicryl 7290 Tds ✓

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.

The following essay presents a structured, TDS‑style synopsis of Visicryl 7290, covering its composition, physical‑mechanical properties, optical performance, processing guidelines, safety information, and typical end‑use scenarios. All data are expressed in metric units and reflect typical values supplied by the manufacturer; actual values may vary slightly depending on batch, thickness, and processing conditions. | Component | Approximate Weight % | Function | |-----------|----------------------|----------| | Polycarbonate (PC) | 55–65 % | Provides toughness, impact resistance, and high heat deflection. | | Acrylic (PMMA) resin | 30–40 % | Contributes to optical clarity, UV resistance, and stiffness. | | UV‑absorbing additive | 2–4 % | Extends outdoor durability by suppressing UV‑induced yellowing. | | Flame‑retardant system (e.g., brominated or phosphorus‑based) | ≤2 % | Meets UL‑94 V‑2 or V‑0 classification for many markets. | | Processing aids (lubricants, stabilizers) | ≤1 % | Improves melt flow and reduces thermal degradation during extrusion. | 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
