Features of pipe insulation tubing:
● Pipe Insulation, Material Black Rubber, Temp Range -40 Degrees to 120 Degrees.
● The pipe insulation has a better function of moisture condensation. Insulation material is both the insulation layer and moisture-proof layer.
● There is no need to drop the water vapor permeation protective layer so that it has a better moisture condensation function.
