Tennis racket handle - is covered with amine-cured bisphenol=A di:glycidyl ether which deforms ergonomically but recovers initial shape after use

摘要

Handle, e.g. for a tennis racket, is relatively easily deformed when gripped so as to fit the shape of a hand, but reverts to its initial shape when released. The handle comprises a resin having Shore-D hardness 50-85, esp. 60-75 at 15-35 degrees C. The resin is an amine-hardened diglycidylether of bisphenol-A, and is directly cast upon the handle core, or may have been moulded as a strip or casting that is subsequently applied to the handle core. The resin is covered by a bushing.
