perfluoroelastomer

MAXMOLD® PF325 is a chemical resistant perfluoroelastomer (FFKM). MAXMOLD® PF325 offers the widest range of aggressive media sealing capabilities along with excellent compression set values.

MAXMOLD® PF325 is suitable for most applications in temperature ranging from -10°C~260°C, offering outstanding resistance to aggressive media such as hot organic and non-organic acids, caustics, ketones, aldehydes, esters, ethers, alcohols, fuels, solvent, sour gases, hydrocarbons, steam, hot water, ethylene, and propylene oxide and mixed process streams. Moreover it can cope with a wide range of potent active pharmaceutical ingredients (API’s) and aggressive cleaning agents, being especially suited to withstand steam-in-place (SIP) and clean-in-place (CIP) procedures.

PF325 can be combined with the cure system and other typical fluoroelastomer compounding ingredients; its mixing can be accomplished with two-roll mills or internal mixers. Finished goods may be produced by a variety of rubber processing methods.

The primary use for PF325 is the manufacturing of any kind of elastomeric sealing element such as o-rings, gaskets, valve bodies, butterfly valves, pump housings and stators, meal bonded parts, diaphragms, profiles, etc. These sealing elements can be used in mechanical seals, pumps, compressors, valves, reactors, mixers, sprayers, dispensers, quick connect couplings, controls, instrumentation, etc. in a wide range of industrial sectors, such as semiconductor manufacturing, chemical process industry, oil and gas, food and pharmacy, and paint spray.

MAXMOLD® PF325 is registered in the FDA Inventory of Effective Premarket Notifications for Food Contact Substances. It can be compounded so that the finished gaskets or seals can be used in food processing equipments.
