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 75ฐC 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.
