Item # 4032-1/32, Reiforced Solid Rubber Tape On Robert McKeown Co., Inc.

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 extrememore
