Coagents for Improved Elastic Recovery in Polyester Urethane Elastomers.

Abstract

A number of chemicals were evaluated as coagents in the peroxide vulcanization of polyester urethanes to determine their ability to produce vulcanizates with good elastic recovery. Several coagents evaluated with high levels (6 pphr) of peroxide produced vulcanizates with improved elastic recovery compared with vulcanizates crosslinked with high peroxide alone. Tensile strength was unaffected while modulus and hardness increased and elongation decreased. Certain coagents when evaluated with low levels (3 pphr) of peroxide produced vulcanizates with improved elastic recovery and only slightly decreased tensile strength compared with vulcanizates cured with high peroxide alone.
