COMPOSITE TUBE WITH IMPROVED MOISTURE EVAPORATION PREVENTING CAPACITY

摘要

PROBLEM TO BE SOLVED: To provide a tube which has moisture evaporation preventing capacity while maintaining elasticity. SOLUTION: An outer periphery of a silicone tube (1) is covered with a thin film (2) of a vinylidene polymer. The vinylidene polymer is polyvinylidene chloride. The thin film is plastic wrap of a thickness of 5-50μm. COPYRIGHT: (C)2004,JPO
