Spunbonded Polyester Nonwoven Fabric

Spunbonded Polyester Nonwoven Fabric is made of continuous spunbonded polyester by needlepunch process.The polyester mat is widely used as roofing substrate of asphalt shingles or , APP or SBS modified bitumen membrane.

The polyester roof substrate has higher tensile strength than PET nonwovens and glassfiber reinforced mat, and smaller shrinake .Currently , PP nonwoven is the first choise for roofing system.

Features:
1. Enhanced flexibility at low temperatures;
2. Excellent dimensional and thermal stability;
3. Superior toughness;
4. Resistance to water and solvent absorption;
5. Isotropic strength and elongation;
6. Exceptional resistance to pull-through and tear off;
7. High fatigue resistance;
8. Superior resistance to delamin;
