Cross Polyethylene Foam (XLPE)
This insulation is caused by the creation of the three -dimensional structure by baking. Also, the thicknesses of 3 to 35 mm are rolled, 40 to 120 mm in mattresses and in the density of 30 to 200. The thicknesses of 10 to 25 mm are produced in size of 3.8 to 5 inches in the foam of the pipe. The above insulators are capable of being lined with a variety of aluminum, metallic, polymer films, PVC.
