Filament Reinforced Spunbond Long Fiber Polyester Nonwoven

Area Weight: 110-300G/M2

 

Raw Material: Virgin PET Chips, Glass Fiber Filament

 

Process: Spunbond, Needle Punched, Glue Bonded

General Information

Isofelt Filament Reinforced Spunbond Long Fiber Polyester Nonwoven is an improved carrier material for various types (SBS, APP, etc.) of modified bitumen waterproofing membrane. 

 

This material is produced with virgin PET chips, reinforced with glass fiber filament/thread, to increase the tensile strength and tear resistance on longitudinal direction during high-speed processing and installation. 

Application

Isofelt Filament Reinforced Spunbond Long Fiber Polyester Nonwoven is an idea carrier material for SBS/APP modified bituminous waterproofing membrane.

 

Compared with non-reinforced polyester nonwoven, this reinforced material has higher tensile & tearing strength on longitudinal direction, which enables it to be applied in high-speed production (with high on-line mechanical tension). The finished bituminous waterproofing membrane has better performance, especially when applied in cold regions, to avoid gapping problem in the joint area due to thermal contraction.
