We at Apple Rubber continue to expand our rubber compound product offerings with the introduction of 02FS7SH, a fluorosilicone elastomer rubber recommended for use in conjunction with petroleum oil, jet fuel, mineral oils, and high and low temperatures.
What is fluorosilicone rubber? Simply, FSR consists of fluoro groups added to the silicone polymer chain. The ASTM International designation for this rubber compound product is fluoro-vinyl-methyl silicone, or FVMQ. The addition of fluorine produces high non-polarity, which gives the polymer superior fuel and oil resistance.
Applications for FSR are unlimited, ranging from engine gaskets to fuel line seals to electrical housing seals. When compounded and processed correctly, FSR can even meet stringent outgassing requirements for aerospace applications.
Apple Rubber’s 02FS7SH was developed to meet the rigorous requirements of AMS-R-25988 Class 3, an aerospace military specification that calls for FSR to display high modulus and increased temperature resistance in O-rings and molded parts like sheets, strips, and extruded shapes.
This new product is able to withstand conditions ranging from -65°C to +175°C. During the development process, heat aging at +225°C and low temperature retraction (TR-10) testing to -62.2°C show the compound’s ability to successfully meet these extreme industrial climate requirements. When the material was exposed to both di-ester oil and a tryimethylpentane /toluene mixture, 02FS7SH provided a capable performance.
Typically, Apple Rubber molds Fluorosilicone compounds into O-rings, but we are capable of molding these compounds into custom profiles. With our in-house mold-making ability, we can provide quick tooling for any profile. We have even bonded seal profiles to different substrates to deliver excellent adhesion to plastic and metals.
