NITRILE Rubber (NBR, Buna-N, Nitrile)Nitrile is the most widely used elastomer in the seal industry. The popularity of nitrile is due to its excellent resistance to petroleum products. It has good physical properties and is superior to most rubbers in regards to compression set, tear and abrasion re

ETHYLENE-PROPYLENE (EPDM)Ethylene-propylene compounds are used frequently to seal in brake systems, and for sealing hot water and steam. Ethylene propylene compounds have good resistance to mild acids, detergents, alkalis, silicone oils and greases, ketones, and alcohols. They are not recommended fo

NATURAL RUBBER (NR)Natural rubber is a product coagulated from the latex of the rubber tree, hevea brasiliensis. Natural rubber features low compression set, high tensile strength, resilience, abrasion and tear resistance, good friction characteristics, excellent bonding capabilities to metal substr

POLYACRYLATE (ACM)Polyacrylates are copolymers of ethyl and acrylates which exhibit excellent resistance to petroleum fuels and oils and can retain their properties when sealing petroleum oils at continuous high temperatures up to 347 °F. These properties make polyacrylates suitable for use in autom

PTFE FilledPTFE Filled has improved mechanical properties over virgin PTFE. The influence of filler materials results in an increase in mechanical strength, increase in hardness, reduction of wear and/or friction, improvement in the flow strength and increase in thermal shape stability. The most im

HYDROGENATED NITRILE (HNBR)HNBR is achieved by hydrogenated NBR. Greatly improved wear and extrusion resistance over standard NBR. Good chemical compatibility and it is excellent heat and oil resistant including exposure to such oil additives as detergents, anti-oxidants and anti-wear agents. It als

SILICONE (VMQ)Silicone is a semi-organic elastomer with outstanding resistance to extremes of temperature with corresponding resistance to compression set and retention of flexibility. Silicone elastomers also have excellent weathering, ozone and aging properties.Silicone rubbers have poor mechanica

NEOPRENE / CHLOROPRENE (CR)Neoprene homopolymer of chlorobutadiene and is unusual in that it is moderately resistant to both petroleum oils and weather (ozone, UV, oxygen). This qualifies neoprene uniquely for certain sealing applications where many other materials would not be satisfactory. Neopren

ETHYLENE ACRYLIC (AEM)Ethylene-acrylic (Vamac) is a terpolymer of ethylene, methyl acrylate, and an acid-containing monomer as a cure site. It exhibits properties similar to those of Polyacrylate, but with extended low temperature range and with enhanced mechanical properties.Ethylene-acrylic offers

FLUOROCARBON (FKM)An excellent elastomer for use in high temperature applications. Also exhibits excellent chemical resistance, commonly referred as FKM. Fluorocarbon exhibits resistance to a broader range of chemicals combined with very good high temperature properties more so than any of the other

FLUOROSILICONE (FVMQ)Fluorosilicone rubber which combines the good high and low temperature stability of Silicone with the fuel oil and solvent resistance of Fluorocarbons. It is most often used in aerospace applications for systems requiring fuel and/or diester-based lubricant resistance up to a dr

STYRENE BUTADIENE (SBR)Styrene-Butadiene (SBR) is a copolymer of styrene and butadiene.SBR compounds have properties similar to those of natural rubber. SBRs primary custom molded application is the use in hydraulic brakes system seals and diaphragms, with the major of the industry usage coming from

Virgin PTFEPTFE Virgin is a tough high temperature material offering the widest range of applications. Resistant to almost all chemicals (only solid alkalies can attack PTFE), its very low coefficient of friction and high impact resistance make it suitable for wide chemical exposure situations, with
