PEF insulation material is flexible with closed cell structure. Adopts the most advanced foaming technology and scientific prescription, mix the branched polyethylene,flame retardant,foaming agent and crosslinking agent together, high rate foaming of the chemical bridge through a banburying and mixing roll way, become a structure of reticular macromolecule. It do not consist poisonous material, and has low thermal conductivity, best moisture resistance factor and fire proof property.Remark: colour is optional

Feature of Starwin PEF insulation pipe

1.Excellent insulation effect : closed cell structure brings a coefficient of thermal conductivity of 0.038w/m.k.oC.

2.Easy and fast installation

3.Long service life: resistant to element, corrosion and impact.

4.Low Integrated cost: long service life make it no need to replace often,saving the cost of material and manpower. Especially energy saving is a long-term thrift due to its good effect on heat and cold insulation

5.Moisture resistance

6.Good fire proofing

7.Non-toxic

8.Buffering
