Polyether Polyol Used for Pipe Insulation is specially researched for rigid PUF to produce thermal insulation pipes. It is widely used in steam pipes, liquefied nature gas running pipes, oil pipes and other fields. The characteristics of Polyether Polyol Used for Pipe Insulation are as follows:
(1) good flowability, by regulating formula to suit different pipe diameters.
(2) high temperature-resistance performance, long standing in 150℃
(3) excellent low temperature dimensional stability
Polyether polyol used for pipe insulation is one of the components of polyurethane foams, Polyurethane foam is produced by reacting two liquid chemicals, an isocyanate and a polyol to form a solid blown matrix. The inclusion of a blowing agent into one of the liquid streams expands the polymer matrix during the change from liquid to solid. Hence, a solid foam is obtained. The chemical reaction is controlled according to the choice of manufacturing process together with a selection of further additives and catalysts. In pre-insulated pipes, rigid polyurethane foam is the material of choice due to the compelling combination of insulation excellence and mechanical properties.
The polyurethane foams are materials wrapped around the pipe which retard the flow of heat energy.
Polyurethane foam helps maintain a warmer pipe temperature to avoid heat loss in pipes and prevent freezing or cracking in cold climates.
Pipe insulation reduces energy losses to a great extent and thereby reduce energy cost.
The insulation of pipes is one of the most commonly used materials in buildings and industrial structures, has a high impact on energy savings.
The thermal conductivity coefficient value of polyurethane foam is lower than other insulation materials such as wood, rock wool and polystyrene, thanks to the high closed cell amount of rigid polyurethane foams.
Therefore, the thermal insulation by rigid polyurethane foams is much higher than other insulation materials.
In pre-insulated pipes, rigid polyurethane foam is the material of choice due to the compelling combination of insulation excellence and mechanical properties.
Fuctions

Functions of Rigid Foam Polyether polyol for Pipe Insulation serves three principal purposes:
1,Hot Insulation: the significant reduction in heat transfer of thermal energy to and from the surface of the piping system. So, piping insulation conserves energy.
2,Cold insulation: the prevention of moisture formation and collection on the surface of the piping system due to condensation on cold surfaces.
3,Personal Protection: the prevention of potentially injurious personnel contact with the surface of the exposed piping system.
