Heating hot and cold water pipeline insulation polyurethane pipe shell manufacturer priceThe porosity structure of polyurethane foam pipe shell material is stable, basically a closed cell structure, which not only has excellent insulation performance, but also has good frost resistance and sound absorption. The average lifespan of the rigid polyurethane insulation structure can reach over 30 years under normal use and maintenance conditions. It can be achieved under normal operating conditions during the service life of the structure, without being damaged by dry, humid, or electrochemical corrosion, as well as external factors such as insect, fungal, or algal growth or rodent damage.
Heating hot and cold water pipeline insulation polyurethane pipe shell manufacturer pricePolyurethane insulation shell, also known as polyurethane tile shell, is a new type of synthetic material that has the characteristics of light weight, high strength, non water absorption, and good thermal insulation performance. It has been widely used in cold storage, refrigeration, transportation vehicles, petroleum industry, chemical equipment, military research, indoor air conditioning, household appliances and other industries. Stable chemical properties, long service life, and no pollution to the surrounding environment; It extinguishes itself from an open flame and only carbonizes without dripping during combustion. The size and shape of the carbonization layer remain basically unchanged, effectively blocking the entry of air and preventing the spread of fire, with good fire safety performance.

Heating hot and cold water pipeline insulation polyurethane pipe shell manufacturer priceIntroduction to Production Technology of Polyurethane Insulation Shell Polyurethane shell is an insulation material formed by high-speed mixing of black and white materials in a 1:1.1 ratio in a mold. The polyurethane pipe shell formed by the use of various additives such as foaming agents, catalysts, flame retardants, etc. (black material) and polyether (white material) can be customized with satisfactory specifications, thicknesses, and special standards of pipeline insulation materials according to customer needs.
Heating hot and cold water pipeline insulation polyurethane pipe shell manufacturer priceIn the polyurethane pipe shell foam, phosphorus containing flame retardant mainly plays a role in the condensed phase. Phosphide can consume the combustible gas decomposed from the combustion of the foam plastic, so that it can be converted into non combustible carbonization. When the phosphorus (P) content in the foam reaches about 1.5%, better flame retardant effect can be obtained. Halogen containing flame retardants mainly play a role in the gas phase. Halogens are chain terminators for the combustion reaction of foam plastics. They generate hydrogen halide during the combustion of plastics to inhibit the combustion reaction. According to relevant data, in order to obtain satisfactory flame retardancy of foam, the mass fraction of bromine (Br) in the dense body should be 12% -14%, or the mass fraction of chlorine (Cl) should be 18% -20%. When phosphorus halogen is used in combination, due to the existence of a certain synergistic effect, 0 5% P+(4% -5%) Br or 1% P+(8% -12%) CI can make polyurethane foam self extinguishing.
