RapidVac Vacuum-Assisted Casting Polyurethanes |
 |
 |
|
Polyurethanes designed by Innovative Polymers for vacuum assisted casting are formulated with 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 molding high-quality, void-free automotive components, electronic parts, medical equipment components and sports/recreation equipment.
Vacuum Assisted Casting Polyurethanes feature low viscosities with rapid gel times. Shore A systems have high elongation and tear strength. Shore D systems include materials with ultra-high flexural modulus, good tensile strength and high heat resistance.
