Rubber Foam Tube and Sheet Rolls
Rubber Foam Tube and Sheet Rolls
The wet resistance factor μ ≥ 10000, improved the product's ability to resist water vapor permeability, to prevent the pipeline condensation, reduce the risk of pipeline corrosion.
Metwell Class0/Class1Rubber Foam Insulation
when the temperature reaches 0 ℃, thermal conductivity is 0.032 W/(m.K), low thermal conductivity, uniform fine closed cell, ensure a great heat preservation effect.Better control balance of the oxygen index and smoke density with foaming chemical reaction fully, highly improved the fireproof and safety.
Advantages
Good thermal insulation property
Excellent water vapor permeability
High performance of fireproof
Easy Installation
