General Information

Isofelt Spunbond Long Fiber Polyester Nonwoven is a nonwoven material, manufactured with high grade virgin PET chips. It has excellent tensile & tearing strength, extensibility & thermal stability, as well as low shrinkage performance. After saturation with bitumen, the roofing membrane finished product is extremely elastic and has high resistance to aging & corrosion.

 

Using virgin PET Chips as raw material, it is produced with spunbond technology, needle punched for mechanical integrity and organic resin bonded to increase stiffness & strength.
