Super Performance Fluorinated RubberSuper Fujikuraflex(SF)

CAT. No. SFS1-1

2008.9

● Super Fujikuraflex is a totally new type of fluorinated elastomer that offers numerousadvantages over existing materials.

● Super Fujikuraflex can be used across an exceedingly wide range of temperatures. SF's unique set of properties offer high performance under extreme conditions and cansatisfy the requirements of the most demanding applications.

● The Super Fujikuraflex series is distinguished from conventional fluorinated elastomers by the introduction of ether linkages along the polymer's main chain. This results in superior flexibility at low temperatures.

●Withstands continuous use across a wide temperature range (-50℃～200℃).

● Excellent resistance to swelling from hydrocarbon fluids such as fuels and lubricating oils.

● Excellent resistance to swelling from most solvents including alcohols, ethers, ketones,

and aromatics.

● Excellent resistance to attack by acids and bases.

● Excellent resistance to degradation by amines.

● No extractable or volatilizable components.Will not contaminate surrounding materials.

● Excellent resistance to water and steam.

● Low compression set with superior sealing

capabilities.

● Excellent stability of physical properties at

elevated temperatures.

● Contains no toxic substances. Causes no

negative effects on organisms.

Product Description

Super Fujikuraflex 7000(SF7000) 70 Shore A, Standard Type

Super Fujikuraflex 5000(SF5000) 50 Shore A, Standard Type

● For applications requiring better low temperature performance, better chemical resistance, and lesstack than existing general purpose fluorinated rubbers.

● For applications requiring even better low temperature performance and chemical resistance thanoffered by conventional low temperature type FKM.

● For applications requiring lower cost and better low temperature performance than PVME/TFE FKM.● For applications requiring lower gas permeability, better chemical resistance, and the elimination of

the volatiles of fluorosilicone rubbers.
