The CRAFTECH 8744 is a transparent polyurethane vacuum casting material designed for applications requiring high clarity and durability. It exhibits excellent transparency and is resistant to yellowing, ensuring the aesthetic integrity of cast parts over time.
This material offers good mechanical properties, including a typical tensile strength of 30 MPa and an elongation of 30%. Its Izod impact strength is rated at 10 kJ/m², indicating good resistance to fracture. The heat deflection temperature is 75 °C at 1.80 MPa, and the glass transition temperature (Tg) is 85 °C, suitable for moderate temperature environments.
Key optical properties include a high total luminous transmittance of 93.1% and a low haze of 0.7%, contributing to its clear appearance. The material also demonstrates good color stability under Xenon lamp exposure, with a color difference (ΔE) of only 0.7 after 50 hours.
Curing conditions involve mold temperatures of 70 °C for 60 minutes, followed by 25 °C for 24 hours. The material is supplied as a two-part system: Part A (Polyols) and Part B (Isocyanates), with a mixing ratio of 100:150 by weight.
