Vacuum Assisted Casting Polyurethanes |
 |
 |
|
Polyurethanes designed by Innovative Polymers for vacuum assisted casting are formulated in hardnesses from Shore 50A to Shore 85D. The product line includes two water clear materials as well as a variety of colorable products. With a broad range of physical performance properties, the systems are well suited for use in a variety of applications:
Vacuum Assisted Casting Polyurethanes feature low viscosities with rapid gel times of four to 18 minutes. Shore A systems have high elongation of tear strength. Shore D systems include materials with ultra-high flexural modulus, good tensile strength and high heat resistance for use at temperatures up to 199ºF (93ºC).
