Cotton linters are short fibers from the cotton flower, which are no longer suitable for the textile industry but which have excellent properties for the manufacture of soft and absorbent filters. In addition to cotton linters, they mainly use pulp, obtained by chemical treatment of plant material. (eg, coniferous wood or deciduous wood). At MACHEREY-NAGEL, only the most experienced specialists choose the raw materials to ensure a very high quality of all our filter papers. For the manufacture of glass fiber filters, they use borosilicate glass fibers (exception: quartz fiber paper). With a diameter of 0.5 to 1.5 µm, these glass fibers are much thinner than cellulose fibers. One of the most important characteristics of glass fiber filters is their resistance to almost all chemicals (exception: hydrogen fluoride.) Filters are available in round, pleated sheet and in different diameters and sizes. Special productions are possible according to your specific needs. Do not hesitate to contact us. The products and their specifications are subject to change without notice. Home Sitemap Mail © Filterservice 2015 ::: Legal Notice ::: Contact
