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.

Flexible, compressible COHRlastic silicone closed cell sponge is designed for high-performance gasketing, thermal shielding, vibration mounts and press pads. It is available in six constructions.
R10470, a general-purpose silicone sponge, can be used in most applications.
R10480 has extremely low compression set and maintains its resiliency even under extended compression.
R10460 is flame retardant.When held in a vertical position and exposed to a 2,000 °F flame for 12 seconds, there is no residential flame and less than a 10 second afterglow. Like R10480, it is especially resistant to compression set.
R10450 silicone sponge with fiberglass reinforcement is a unique construction. It has the compressibility of sponge, plus dimensional stability in the X-Y direction. The absence of stretch contributes to the consistent size and shape of die cut parts and eliminates outward extrusion under pressure.
R10490 fluorosilicone sponge rubber can be used as a gasket where it is necessary to contain fluids that would degrade normal silicone sponge and solid materials (special order basis).
R10404 closed-cell conformable silicone rubber sponge is designed for use where both conformability and heat transfer are necessary, such as between printed circuit boards and heat sinks, decal transfer or applying heat activated adhesives.

Strip-N-Stick® tape provides all the benefits of silcone rubber in an easy-to-apply, pressure-sensitive adhesive tape form. Compressible and flexible, it can conform to irregular surfaces, wrap over cylinders or be formed to produce right angles. Applications include gasketing, vibration damping, and thermal insulation.The tape reduces the need for expensive diecut- parts – you don‘t pay for the center. It also eliminates the high cost of bonding and will be slit to order from 1/2" and up.
100S is a silicone sponge with high temperature silicone adhesive.
200A is a silicone sponge with aggressive acrylic adhesive.
300AR is reinforced silicone sponge with aggressive acrylic adhesive. Its unique construction provides compressibility of sponge and dimensional stability of fiberglass reinforcement. Stretch is eliminated, which contributes to the consistent size and shape of cut parts and inhibits outward extrusion under high pressure. It further permits close tolerance slitting.
440S is a 1/32" thick Shore A 30 durometer silicone solid with high-temperature silicone adhesive.
440A combines 30 durometer solid rubber with a high-adhesion acrylic adhesive for an excellent 1/32" thick gasket material. It provides high elongation and good comformability.
512AF uses SGPPL CHR’s silicone foam along with film-supported acrylic pressure-sensitive adhesive.
Adhesive temperature range for Silicone PSA is –100 °F to +500 °F and for Acrylic PSA, –20 °F to +300 °F.

Low-density, flame-retardant COHRlastic silicone foam yard goods provide outstanding performance for industries ranging from aviation and mass transit to automotive, electronics, construction and furniture.
In addition to a UL94V-0 listing in thicknesses down to 1/16", it withstands a 2100 °F flame for more than 10 minutes without burning through in thicknesses down to 3/8".
The material, which has a nominal density of 12 pounds per cubic foot, generates very little white smoke.
Non-corrosive for use with metals and in hostile environments, it has low compression set. Among its applications are fireblocks, thermal barriers, noise and vibration dampeners, insulation and high-performance gaskets or seals.
For the aviation, automotive and mass transit industries, it offers a high degree of design flexibility. Lightweight and easy to process, it can be laminated to seat cover fabrics and carpeting as a backing for added flame resistance in passenger compartment furnishings.

The material has similar uses in institutional and residential furnishings, marine and lighting applications. It offers properties valuable in flame retardant backings for floor,wall and furniture coverings; fire-wall and thermal barriers or insulation, padding and gasketing for commercial and private marine vehicles; or gasketing and sealing in high- intensity light fixtures and electronic components in medical, computer and business equipment.
Colored gray, it is supplied in 18" and 36" wide roll stock. Thicknesses are shown in the table below. It is available plain or, on special order, laminated to any of a wide range of substrates.
Because of the unique nature of COHRlastic foam, SGPPL CHR has undertaken a rigorous testing program which is performed at outside independent laboratories.
The tests document the flame resistant properties and low levels of toxicity and smoke generation as well as mechanical and electrical properties. Details are on file at SGPPL CHR.

Tests, claims, representations and descriptions regarding flamability are based on standard laboratory tests and, as such, may not be reliable for determining, evaluating, predicting or describing the flammability or burning characteristics under actual fire conditions, whether used alone or in combination with other products. Accordingly, each potential user should make an individual determination whether the flammability or burning characteristics of the product are suitable for the purpose intended by the user.

CHR provides certification to the specifications listed when requested with order. All properties are typical values and should not be used for writing specifications. Please consult plant concerning updated specifications. Government and military specifications are being revised at the time of this catalog printing.
