Filter bags made of polyester needle felt with oil and water repellent PTFE-based finish are characterized by immunity to acids, alkalis and hydrolysis in high humidity working conditions.
The presence of PTFE is obtained by adding a polytetrafluoroethylene solution to the resin full bath.
In addition to the regular oil and water-repellent properties, the filter media obtained is effective in a chemically aggressive working environment. The product has the following characteristics: moisture resistance, better regeneration, low cost of use, long working life, anti-adhesiveness together with strong chemical resistance.
