Document Type and Number:
Japanese Patent JP2003534945
Kind Code:
A
Abstract:
A bi-layer covering sheath has a foamable polymeric inner layer, and a non-foamable non-heat-shrinkable polymeric outer layer surrounding and in intimate contact with the inner layer; the outer layer having a melting point that is at least 60° above the melting point of the inner layer, and the thickness and mechanical strength of the outer layer being such that the sheath retains substantially constant outer dimensions at a temperature sufficient to cause foaming of the inner layer. These sheaths are tubes for covering, generally, elongated substrates such as tubes, rods, wires, and cables, especially tubes, and caps for covering an end of such substrates.
