WE HAVE BEEN A U.S. MANUFACTURER AND LEADING PRODUCER OF
MIL SPEC GRADE FLUOROSILICONE RUBBER SHEETS FOR OVER 50 YEARS

AA25988.com is an online resource for Ja-Bar Silicone’s Mil Spec grade fluorosilicone rubber sheets.
We supply to top defense contractors as well as many well-known leaders in the automotive,
aviation, petrochemical, electronics, food, and leisure industries.

Do NOT compare our Mil Spec grade fluorosilicone rubber sheets to other commercially available,
advertised fluorosilicones. Performance qualification data must be evaluated.
Formula qualification data and batch test results are available with every shipment.

YOU ARE BUYING DIRECT FROM THE SOURCE
WE ARE THE MANUFACTURER, NOT A DISTRIBUTOR OR RESELLER
This enables us to give you the best price, availability, and on-time delivery.

High & low temperatures environments ■ Outdoors ■ Electrical insulation ■ Environmental insulation
Where chemical resistance is needed ■ Extreme temperature resistance ■ Excellent ozone and weather resistance
Good compression set characteristics ■ Radiation resistance ■ Chemical resistance, including excellent oil resistance

Fluorosilicone sheeting is available to MIL-R-25988 as well as other fluid-resistant specifications.
The material has better fuel and oil resistance than other silicone elastomers, but maintains silicone’s high temperature advantage.In applications where contact with jet fuel, solvents, gasoline, or crude oil is required, this elastomer is serviceable over a temperature range of -60ºC to 177ºC (-76 to 350ºF). In dry heat, the serviceable temperature range is extended up to 232ºC (450ºF).Physical properties (including tensile strength, elongation, and tear resistance)
are comparable to those of general purpose silicone rubber compounds.
