DuPont Tyvek


Nonwovens are also used as filters against certain substances, especially when a certain amount of air circulation is required. These substances may be solids such as powders, but also liquids such as water and oil. The product range of King Nonwovens B.V. includes a suitable product for every filtering job.

DuPont™ Tyvek®

DuPont™ Tyvek® is a fleece product made of 100% high-density polyethylene (HDPE). It is manufactured by first spinning endless, very thin yarns, which are then bonded together by means of heat and pressure. This gives Tyvek® exactly the right properties to filter out very tiny particles.

DuPont™ ACT®

DuPont™ ACT® consists of three layers. The intermediate layer is a film with excellent filter characteristics. As the top and bottom layer are made of a different polymer with a higher melting point, ACT® has excellent welding characteristics.
In addition to these two products, King Nonwovens B.V. has many more nonwovens in its product range which, depending on the envisaged application, can also serve as filters. For instance, a Typar® of polypropylene or a polyester nonwoven may be eminently suitable as a filter.
