ABSTRACT:
First and second bodies of heat recoverable polymeric material are fusion bonded together with their directions of recovery at an angle to each other, the bond preferably being cross-linked after bonding to enable the resulting article better to withstand the recovery forces encountered in use. The invention is especially useful for making wraparound tubular enclosures for "T"'s and bends which enclosures in use will recover radially about two tubular axes.
