    PEF Insulation Piping

    PEF insulation pipe is made using advanced foaming technology, formed by blending various raw materials such as a high-pressure polyethylene flame retardant foaming agent and cross-linking agents that pass through open or sealed refining where a high separation foam of polyvinyl hydrocarbons is chemically bridged. The product takes on a network polymer structure, which balances the products with open-cell type bubbles, and then uses mold-rolled tube pile insulation material.

PEF insulation pipe

Polyethylene PEF thermal insulation material is made of special process products, its foam hole is closed hole structure, it has the characteristics of heat insulation, moisture, dew prevention, anti-aging and so on, widely used in central air conditioning and various cold and hot quality pipeline heat insulation, moisture, cold protection and so on.

Polyethylene insulation material is a high-performance energy-saving material, under the same conditions, with less materials than other materials, and the construction is convenient and fast, in order to shorten the engineering cycle, improve the construction treatment, improve the reliable guarantee.

Good fire performance: adiabatic material not only produces common type but also produces flame retardant type (oxygen index 32) two kinds of high-grade adiabatic material that can meet different fire requirements.And the product in the existing foam insulation materials and domestic similar products smoke toxicity for the minimum.

Weathering type: prosperous adiabatic material because crosslinking density is high, stability is good, ultraviolet ray irradiates 300 hours artificially, surface layer does not have change, service life is long.

Corrosion resistance: can be resistant to a variety of chemical drugs, soaked after the basic deformation, not cracking, so can be widely used chemical pipeline, tank insulation.

Low temperature resistance: in strong low temperature, the material structure does not damage, deformation, cracking.

Non-toxic: flourishing insulation material does not have any toxic substance.In pyrolysis, no harmful gases will be produced.

Cushioning: the impact resistance and cushioning of the thermal insulation material are the best for other thermal insulation materials.

Other advantages: beautiful, a variety of colors for choice;Easy to process and conform with other materials;Soft and smooth, good touch;Light as cotton, etc.
