Please Note: This compatibility chart is intended as a quick reference guide. We recommend testing under actual conditions to ensure compatibility. The ratings apply to tests in which samples were immersed for approximately seven days at 75°C and is determined by the volume change according to the following scale: Excellent (0-3% change), Good (4-15%), Fair (16-35%), Poor (36% and up).At Nuraseal, we utilize two main categories of elastomeric materials: liquid-cast thermoset ployurethane and injection-moulded thermoplastic polyurethane. Depending on your particular requirements, other materials are also available. Please contact us for details.
