Soflon Tube Insulation With Film

Softlon FR Tube is made from closed cell physically crosslinked polyolefin foam with embossed UV treated clear film. 

Softlon FR Tube’s low thermal conductivity combined with low water absorption and vapour permeability make it ideal for insulating air conditioning and refrigeration systems as well a drain pipes and hot water pipes.
