Rubber Sponge

OPEN CELL

Open cell sponge is a unique product that qualifies for many applications in cushioning, sealing and vibration dampening It's characteristics to compress and recover provides sup-port throughout the area of contact. Open-cell provides excellent low-pressure sealing against air gasses, and fumes. In addition, it is particularly suited for sound suppression, isolation and reduction of vibration. It is available stripped, die cut and laminated to various materials. Also, adhesive backing is available on request. - … best natural skin surface in the industry and tops in resilliency. Twist it, compress it, stretch it. It always recovers! - CLOSED CELL Expanded Closed Cell neoprene with non-interconnected cell structure. Impervious to water or moisture, air dust, and many aromatic and chemical fumes. Is available in Nitrile, EPDM and P.V.C. Standard Stock Sizes Rolls 42" x 50' Thickness: from 1/16" to 1" Stripping to any width is done in our factory. Adhesive backing can be applied to one side or both. - … and impervious to moisture, dust, air because the cells are not interconnected. Light in weight, bondable and easily cut. - - - Sponge rubber extrusions to your specifications or our stock dies.

	Gasket Packing

Common Name	Duro- Meter Range	Tensile Elong.	Temp. Range ¡F	General Properties
Natural Rubber	20-100	3200 800	-65 +212	Excellent tear resistance, tensile strength, resilience and abrasion resistance. Used where a soft rubber seal is required. Resists most inorganic salts, ammonia, acids and alkalis.
Black Rubber	40-100	700 300	-65 +250	Fair weather and ozone resistance. Good physical properties including abrasion resistance. Resists flow under compression-generally used for non-oil resistant, medium pressure applications.
Red Rubber		700 300	-65 +250
C.I. Rubber	40-100	700 300	-65 +250	Same as SBR except it is used where creeping in service indicates a reinforced sheet packing, and the stresses are usually static.
Butyl	30-80	1500 500	-40 +300	Excellent gas impermeability, outstanding dielectric properties, high resistance to chemicals and acid, resists weathering.
EPDM	30-90	1650 450	-90 +350	Excellent resistance to heat, aging, oxidation, ozone, acids, alkalis, hydraulic fluid, good electrical resistively.
Buna-N	20-90	1000 400	-40 +200	Excellent resistant under extreme exposure to petroleum oils, gasoline, aromatic gasses. Outstanding compression set and heat resistance.
Neroprene	10-95	1000 400	-40 +200	Good oil and weather resistant properties. Excellent for mounting pads, diluted acids and alkaline applications.
Hypalon	50-95	2400 400	-40 +300	Excellent acid resistance such as concentrated sulfuric and hypochlorite solutions. Outstanding weather, oil, abrasion, flame and heat resistance
Urethane	55-100	4000	-40 +250	Highest available abrasion resistance, tensile strength, and load-bearing capacity. Excellent resistance to oils.
Silicone	25-80		-165 +500	Outstanding high and low temperature range, odorless, tasteless, non-corrosive and non-contaminating. Resistant to compression set at high and low temperature ranges.
Viton	65-90	2250 300	-40 +400	Excellent hot oils, commercial fuels, solvents and chemicals resistance. Good physical properties.
Thiokol	20-80	Max. 1500	-40 +200	Excellent solvent resistance. Excellent weather resistance.
Teflon		Over 2000	-40+500	Excellent general chemical resistance. Excellent high temperature qualities. Outlasts other materials as a seal for steam.
