The significance of testing the water vapor permeability of rubber insulation pipes is that the thermal insulation ability of rubber foam insulation materials relies on the gas inside a large number of tiny bubbles. Within a reasonable range of bubble diameters, the more thorough the foaming, the higher the gas content in the material, and the better the insulation effect. In actual use, both sides of the inner and outer walls of the rubber insulation pipe ..

2. The method for testing the water vapor transmission rate of rubber insulation pipes mainly refers to the standard BSEN13469-2001 "Determination of Water Vapor Transmission Rate of Thermal Insulation Products and Prefabricated Pipe Insulation Layers for Building Equipment and Industrial Facilities". This standard requires the testing chamber environment to be controlled at temperature ..

3.The foam insulation material adopts an automated production line, using high-performance nitrile rubber and polyvinyl chloride as the main raw materials, and is made through special processes such as mixing, vulcanization and foaming
