Product Details

Introduction

Polyester mat is made from highly strong 100%polyester nonwoven fabric.It is reingorced superior and edible starch solution and dried by stoving which make it high intensity,high extension and puncture resistance.And it’s the first chosen bottom cloth for SBS/APP modified asphalt waterproofing membrane.

Application

1. An ideal substrate material for asphalt roofing rolls shingles.
2. An excellent basic material for waterproof building materials.
3. act as the lining for rood insulation laywes to protect polyester foam insulation from the damaging effect caused by chemical solvents in bitumen so as to prolong the lifetime of heat insulation layer.
4. Mainly used for storing water pool,flooring,underground the surface of bridge,waterproof project and corrosion resistance in indoor ground building bases.

Characteristic:

1) Good impermeability.

2) SBS waterproofing rolling material can be applied in very cold area with low temperature.
3) Good performance in anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew,

anti-weathering.
4) Possess good tensile strength, elongation rate and size stability which could be well suited

and substrate distortion and crack.
