Saint Gobain™ Conductive Silicones
FRF3320, available in three thicknesses, is designed to meet AMS 3320. Consequently, 3320 has lubricating oil resistance and excellent compression set resistance.
FR4032 and FR4050 are thin, flexible and abrasion-resistant fiberglass-reinforced gasket materials intended for general purpose use.
FR4420 is a specially formulated for thermal stability and long life under extreme heat and pressure and extended dwell times. It resists reversion (i.e. softening and outgassing) longer than general purpose silicone. Throughout its useful life, 4420 has thermal stability for consistent thermal conductivity.
FR4444 has specially formulated rubber compound to give better reversion resistance. The reinforcement is a special crush-resistant fiberglass, making the product excellent for press pads in high-temperature and pressure lamination applications.
FR4451 is a fiberglass fabric coated with static dissipating silicone rubber having a surface resistivity of 1 x 10 ohms-cm. This product virtually eliminates static electric discharges which cause operator discomfort and can potentially damage electrical laminates.
FR4480 utilizes the most reversion-resistant silicone rubber compound. This material is designed for use in applications involving the tough combination of prolonged high-pressure confinement with temperatures in the range of 375° F to 650° F.
Adhesive Backings
Auburn can apply pressure sensitive silicone or acrylic adhesives to standard sheets (36" x 36" or 24" x 24") or continuous length rolls at 36° wide. The self-adhering materials permit substantial savings because they are easy to apply, simplify production, and eliminate the high cost of bonding. SP-2021 Silicone Adhesive withstands the same temperature extremes, -100° F to +500° F, as the silicone rubber sheet. AP-2022 Acrylic adhesive, whose temperature range is -40° F to +300°F, offers the same advantage of twice the adhesion to steel and a longer shelf life than silicone adhesive.
Hi-Temp Acrylic Adhesive, newly released, is capable of withstanding temperature of 450F, while providing the high-bonding strength of acrylic adhesive. All of these above-mentioned electrically or thermally conductive silicones from Auburn are readily available either plain or with an adhesive backing applied to one, or in some cases, both sides. Self-adhering adhesive-backed sheets are protected by an easy-to-remove peel-off liner for application to a clean, dry, degreased surface.
