polyester asphalt felt bottom cloth for APP/SBS bitumen waterproof membrane

Polyester asphalt felt bottom cloth for APP/SBS bitumen waterproof membrane

Polyester asphalt felt bottom cloth for bitumen membrane making materials is type of base material for making SBS/APP modified bitumen waterproofing membrane, it is staple fiber non woven fabric.

There have National standard and nonstandard.

1)polyester mat can be used for reinforcement layer of SBS and APP waterproofing membrane, it`s the ideal substrate materials for asphalt waterproofing felt and shingles, there is excellent binding strength with the modified bitumen materials.

2)High tensile strength, high tear strength, higher elongation property, higher measure stability and resist shrinking in the high temperature process.

3)Excellent corrosion resistance, high aging resistance, thermal stability and very good soaking in modified bitumen liquid.

4)Protect polymer foam insulation from the damaging effect caused by chemical solvents in bitumen to prolong the life time of heat insulation layer.

APPLICATION:

1.An ideal substrate material for bitumen waterproof membrane.

2.Mainly used for storing water pool, flooring, underground the surface of bridge,

3.waterproof project and corrosion resistance in indoor ground building bases.
