Excellent Acid And Chemical Resistance Fpm Fluorine Rubber O Ring Cord And Pump
Fluoroelastomer FKM is have good chemical performance in the elastomer rubber.
Working temperature: -20 to 250 degree
Sealing type: static seal or dynamic seal
In Machinery and chemical industry acid is very common.
Excellent performance copolymer FKM in different acid:
Arsenic acid
Benzene sulfonic acid
Benzoic acid
Boric acid
Carbonic acid
Chromic acid
Cresylic acid
Maleic acid
Oxalic acid
Perchloric acid
Phosphoric acid
Phosphorous trichloride acid
Salicylic acid
Tannic acid
Tartaric acid
Trichloroacetic acid
Sealing appearance and processing method:
Acid form might be gas or liquid. Gas or liquid both can be circulated in rubber hose or it might be rubber cord be
touched with different acids.
Cord size: 1mm to 30mm by extrusion. Bigger than 30mm size made by compression molding
Hose size:thickness from 1mm to 10mm. OD less than 30mm by extrusion. OD more than 30mm made by
compression molding.
Special shaped sealing: as per drawings we will check what is the best processing method.
Except acid Fluoroelastomer FKM FKM also have good heat resistance/ozone resistance/weather resistance/water
resistance/good machinability.
Application: Modern aviation, missile, rocket, semiconductor, automobile, petroleum, chemical, machinery and other industries.
