FILTER PAPER

Chemfil produces a wide range of filter media used for air oil fuel hydraulic applications. The filter paper is treated with resins like Novalac, Resol, Non - Curing type - NC, Acrylic etc. as per the requirement. The process is performed to maintain the texture of the base paper uniformly and firmly. At the same time, it also acts as the process of resin coating and corrugation to maximize the efficiency of filtering and burst strength. Our paper products are made to deliver ultra fine solutions for various critical filtration needs. We are an approved vendor of M/s Indian Railways to supply filter paper for their primary secondary fuel oil filter cartridges.
