Filter materials

Filter cartridges

VYON® and GURON® are filter materials made from porous, low pressure polyethylene manufactured using a modern sinter process. The individual polymers melt at their contact points to form an open-pored filter material.

VYON® and GURON® are porous plastics and therefore used in depth filters. They act as good filter material because they trap particles on their surfaces and in the labyrinth-like paths through the material. The filtering effect can be increased by increasing the thickness of the material or the wall thickness.
