This treatment makes it more difficult for moisture to penetrate into the needlefelt. Thus the risk of excessive dust deposits and caking is reduced.
Special impregnation based on TEFLON®. This treatment coats the fibre surface, thus providing it with the antiadhesive character of a PTFE finish.
An oil- and water-repelling effect is produced, and the fibres are effectively protected against acid and hydrolysis attack.
Special water-repellent treatment providing a high cleaning and separation efficiency.
