CF silicone solid rubber reinforced with fiberglass is a dimensionally-stable, durable material for press pads, belting and gasketing. It is available in six constructions.
CF3320, available in three thicknesses, was developed to meet AMS 3320. Consequently, 3320 has lubricating oil resistance and excellent compression set resistance.
CF4032 and CF4050 are thin, flexible and abrasion-resistant for generalpurpose use.
CF4420 is specially formulated for thermal stability and long life under extreme heat and pressure for 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.
CF4444 has a 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.
CF4451 is a fiberglass fabric coated with static dissipating silicone rubber having a surface resistivity of 1 x 105Ohms – cm.Virtually eliminates static electric discharges which cause operator discomfort and can potentially damage electrical laminates.
CF4480 utilizes our most reversionresistant silicone rubber compound. The product is designed for use in applications involving the tough combination of prolonged high-pressure confinement at temperatures in the range of 375 °F to 650 °F.
