Non-Asbestos Gaskets are made from a mixture of Aramid, Carbon Fiber, Mineral Fiber, Glass Fiber and NBR, SBR, EPDM, Hypalon Rubber. Vegetable fiber Gaskets are very low cost alternative and though economical will never give the same performance as the Aramid nonAsbestos Gaskets or even the old Asbestos Gaskets. Non-Asbestos Gaskets are also referred to as 100% AsbestosFree Gaskets. Recommend demanding proper certification for Product, Manufacturing Plant & Medium compatibility.
Aramid based Gaskets offer 5X Times better performance than even CAF Gaskets. Inspite of this, Vegetable Fiber Gaskets being economically comparable to CAF are erroneously used. These Gasket Sheets manufactured by paper making techniques utilizing plant fibers and a glue-glycerine impregnation can only be used for sealing simple solutions with low pressure and low temperatures. Its maximum temperature limit is 250°F (120°C) and pressure (35 Bar). While, Aramid and Glass FIber Sheets can even go all the way upto 600 Deg C (API 607) certified and offer better acid and alkali protection. Aramid Sheets offer the best performance for general applications involving pressure of more than 50 Bar. Carbon Fiber based Sheets offer the best performance in Acidic environments.
Metallic reinforcement is not required in nonAsbestos Gaskets. We offer Donit Tesnit (Made in Europe) 100% AsbestosFREE Certified nonAsbestos Gaskets.
