According to the physical properties, it is divided into I type and II type. According to the upper surface insulation material, it is divided into polyethylene film (PE), fine sand (S) and mineral pellet (M), fine sand.

Product Specification:


The product is made of polyester felt as the base, styrene-butadiene-styrene (SBS) thermoplastic elastomer modified bitumen as the impregnating and coating material, and the both sides are covered with the insulation   material.





High tensile strength, high water pressure resistance, high elongation, good puncture resistance, fatigue resistance, good dimensional stability, super aging resistance, etc., and strong adaptability to shrinkage deformation and cracking of the base layer.

Resistant to chemical corrosion, mold and weather resistance.

Excellent high and low temperature resistance, keep function at -50 °C, suitable for hot and cold areas, especially suitable for cold areas.

The construction performance is good, the hot melt method is bonded, and the hot joint is reliable and durable.

The knot is firm, the lap joint should overflow the hot-melt modified bitumen, and the blasted parts of the fine sand and mineral granules should be grit-treated, and the detail nodes should be additionally treated, and the lap joint and the head should be sealed. After the acceptance of the polyethylene film-coated coil material, the protective layer shall be set according to relevant specifications and design requirements.

Hot melt construction

The hot-melt method is adopted. Before the construction, the base layer treatment agent (full-adhesive method) should be evenly applied, and then the elastic direction of the construction direction should be determined to determine the position of the coil material, and the coil material is unfolded at the position of the elastic line to release the stress. The coil is rolled from the two ends to the middle, and the hot melt adhesive of the bottom of the coil is baked with a flame spray gun, and the coil is laid from the middle to the both ends, and the paving is compacted by a press roll to remove air, so that the coil is adhered to the base layer.
