Polyester Staple Fiber
PRF polyester staple fiber mats are high-quality mats, mechanically (needle punching), chemically (using a binder) or thermally (calandering) stabilized. PRF mats were reinforced lengthwise with fiber glass thread (every 10 mm), further improving their dimensional stability. PRF mats are made 100% from recycled polyester.
Features:
Dimensional stability
Fast bitumen absorption
Wide range of available grammages
Resistance to biological, chemical and environmental agents
