It has high resilience, good compression set, food roll building behavior, and molding properties, very good friction surface, but not a fine smooth surface when ground, high tear strength, low crack growth, usable for ketones and alcohol, and good low temperature properties. ZipSeals allow for quick replacement of seals on-site. Never miss a dive again!
