Since the early 1970's Johns Manville has produced Polyester spunbond nonwovens.
The unique technology process creates products with the excellent properties of a uniform surface, high tear strength and high porosity.

Polyester spunbond is a manufactured sheet of randomly orientated polyester filaments bonded by calendaring, needling, chemically or a combination of these methods.

Our production range covers weights from 15 to 500 g/m² and roll widths up to 540 cm.
