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.

Excellent Heat Preservation Insulation

The high density and closed structure of selected raw material has the ability of low thermal conductivity and stable temperature，so the inside of the copper liquid pipe will not be affected even if the weather is frozen outside

Eco-friendly Material

The environmental friendly raw material has no stimulation and pollution, it can avoid the mold growth and mouse biting; The material has the effection of corrosion-resistant, acid and alkali, it can increase the life of using.

Excellent Flame Retardant Properties

The material contains a large amount of flame-retardant cigarette raw materials, and the bath fire is not easy to burn and melt, the range of Using temperature is from -40℃ to 120℃

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.

The pipe insulation has many functions such as Heat Preservation Ability, Environmental pollution free, Good flame retardant properties and so on. Besides, it can make your home more tidy and protect the copper pipe in summer.
