The insulation layer of solar water heater water tank mostly adopts PU insulating materials. The density of PU at 40kg/m3 can get optimum insulating effect.
Application of phenolic foam in pipeline insulation
It is widely applied in cold and hot water pipe, fire control pipeline, water supply and drainage pipeline, heat distribution pipeline, petroleum delivery pipeline, etc.
Phenolic foam insulation pipe body is composed of protective layer, phenolic foam, male and female button and seal adhesive tape. The outer protective layer adopt aluminium-foil paper, aluminium foil, iron sheet, glass reinforced plastic based on the features of insulation pipeline.
It is convenient for construction and essential in pipeline seal, it directly influences the advance rate of the construction.
