ABSTRACT:
A novel method for dilating cold shrink articles such as insulating tubing is disclosed. The method makes use of a two phase bath comprising two immiscible liquids in which the lower phase is a swelling agent for the cold shrink material and the upper phase serves as a protective blanket which eliminates the generation of fumes by the swelling agent.
