Polyester spunbound mats are available in grammages from 160 g/m² to 250g/m² and are mechanically (needle punching), chemically (using a binder) or thermally (calandering) stabilized. PRS is reinforced lengthwise with fiber glass thread, making it highly dimensionally stable.
Features:
High dimensional stability
Low shrinkage
Quick impregnation
Flexibility
