New Johns Manville Development: Dynaweb™ PBT

As a result of recent breakthroughs in melt blown technology, Johns Manville is pleased to announce at the INDEX fair in Geneva the development of the new Dynaweb™ PBT. This new PBT polyester-based product is used in filtration media. Johns Manville is commercializing the recently developed Dynaweb™ PBT for liquid filtration in the medical area and industrial hydraulics. This product will provide a different set of chemicals and thermal resistance for specific applications especially in industrial areas. Dynaweb™ PBT can be sterilized by gamma irradiation, which is very important for medical applications and does not exhibit antimony contamination, providing unique product performance. Excellent uniform properties characterize this new product. Currently, Dynaweb™PBT is supplied in weights from 10 to 200 g/sqm and mean flow pore sizes from 1 to 14 microns, as single layer or multi-layer calandered roll goods.
