Material superiority of PTFE seals

Pure PTFE sealing material is resistant to almost all hydraulic media, solvents and various chemical media, has a very low coefficient of friction, no creep, its temperature range -55 ° C ~ 260 ° C chemical stability, ozone resistance, electrical insulation, Excellent flame retardancy and weather resistance, and a series of unique properties such as self-lubricating and non-tacky, which is unmatched by other engineering plastics. In order to improve its resistance to cold flow, IKSONIC Seals usually adds filler material during its manufacture. Pure PTFE seals are especially suitable for the food, beverage and pharmaceutical industries. Filled PTFE is suitable for almost all working conditions. It is generally used with elastomers or springs as elastic members. It is widely used in hydraulic, compressor, chemical and other industries.

Regardless of the mechanical equipment, the friction surfaces that slide against each other during operation need lubrication to reduce the friction factor and reduce the wear and heat of the parts and seals to ensure the precision of the machinery, normal running capacity and power consumption. PTFE The low friction factor and self-lubricity make it a large number of materials used in the manufacture of bearings, piston rings, machine tools and seals.

IKSONIC’s mechanical seals made of PTFE can be used at 260 ° C for a long time, not only can withstand various media, but also work in the absence of oil or oil. Oil seal seals made of a large amount of nitrile and acrylate rubber used in the past are generally only used at 150 ° C and are easily damaged in the absence of oil, so they are gradually replaced by PTFE oil seals.
