Products Spunbond

 

 

The nonwoven Spunbond polyester is a product produced employing the world state-of-the art technology called Spunbond and is used as a strong basis with high tensile strength in the water proofing bitumen sheets. Today, the former method of tissue and regular polyester is totally abandoned in the US and Canada due to environmental problems and low tensile strength, being substitutes by Spunbond as strongest engineered materials for water proofing bitumen sheets so far known, that prolongs useful lifetime of the products many folds.

Advantages of PET Spunbond in WPBS

1-Resistant to water and solvents

2-High temperature resistivity preventing the product's        deformation

3-Different from the PP Spunbond, the PET Spunbond is resistant to Gamma Ray

4-Flexibility at low temperatures

5-Exceptional resistance to tensile stress (Lengthwise and widthwise)

6-High resistance to tearing (Lengthwise and widthwise)

7-High strength against fatigue and aging

8- High resistance to exfoliation

9- High resistance to piercing

10- High resistance to strokes

11- High resistance to chemicals

12-High adhesion to pitch
