Sheet Rubber Product Information
UIP International Inc, offers a full line of commercial grade sheet rubber products which are manufactured under strict guidelines for exceptional quality. Large Inventories of elastomers are available from stock including Neoprene, Red Rubber, CI Sheet, EPDM, Nitrile, White FDA Sheet, Pure Gum, CSM, Butyl and Viton®. Rubber products in storage can be adversely affected by the following items: The warehousing area should be relatively cool, dark and free from dampness and mildew. All items should be stored on a first-in, first-out basis, since even under these conditions, an unusual length of shelf life could deteriorate certain products.
Note:
• All sheet packing sold in full one piece roll quantities, except Viton®
• Price is per pound for actual shipping weight, however, square foot, square yard, lineal foot and lineal yard prices can be provided.
• Freight: F.O.B. Houston; $3000 freight allowed or $3500 combination orders (Sheet Rubber, Industrial Hose and/or AIC Couplings).
• Made to RMA’s specifications
• All orders confirmed back to customer for error-free shipping
• Drop shipments sent to your customer blind with your packing list when required
Special products, not stocked, can be quoted for a factory order. For examples: special sizes, elastomers, duros, special specs and/or molded products.Storage of Rubber Products
• Temperature
• Humidity
• Ozone
• Sunlight
• Oils
• Solvents
• Corrosive liquids & fumes
• Insects & rodents
• Radiation
The ideal storage temperature for rubber products is 50° to 70°F with a maximum limit of 100°F. If stored below 32°F, some products may become stiff and should be warmed before being placed into service. Rubber products should not be stored near sources of heat, such as radiators and base heaters. Rubber products should not be stored under conditions of high or low humidity. To protect against the adverse effects of ozone, rubber products should not be stored near electrical equipment that may generate ozone and should not be stored for any lengthy period in geographical areas of known high ozone. Conditions of direct and reflected sunlight should also be avoided. Whenever feasible, rubber products should be stored in their original shipping containers, especially when such containers are wooden crates or cardboard cartons, since this will provide protection against the deteriorating effects of oils, solvents, and corrosive liquids, and will also afford some protection against sunlight. Certain rodents and insects thrive on rubber products, so adequate protection should be provided from them.
Rubber Properties
Rubbers or elastomers are mixed with various chemicals in order to provide the reinforcement and curing ASTM Designation D1418-79 Common Composition General Properties NR Natural Isoprene, natural Excellent physical properties including abrasion and low temperature resistance. Poor resistance to petroleum-based fluids. IR Similar to natural rubber SBR SBR Styrene-butadiene Good physical properties and abrasion resistance. Poor resistance to petroleum based-fluids. CR Neoprene Chloroprene Good physical properties. NBR Buna N Nitrile-butadiene Excellent resistance to petroleum-based fluids. Good physical properties IIR Butyl Isobutene-Isoprene Very good weathering resistance. Excellent dielectric properties. Low permeability to air. Good physical properties. Poor resistance to petroleum-based fluids. EPDM EPM Ethylene-propylene rubbers diene Ethylene-propylene Excellent ozone, chemical, and aging resistance. Poor resistance to petroleum-based fluids. FPM or FKM Viton, Flourel Hexaflouro-propylene- vinyl-idene fluoride Excellent oil and air resistance at both high and low temperatures. Very good chemical resistance.

Please Note! The general properties shown in the chart on the general properties chart are not intended to be used to make final choices for a specific application. Exposure to heat, sunlight, chemicals, ozone and oils, as well as pressure, tension, binding, stretching and folding, will affect the performance of a rubber product. Suitability must be determined by a qualified person.
