Kalrez® Industrial O-Ring Compounds

Kalrez® 7075

A new compound with enhanced physical performance properties including very low compression set (15% O-rings per ASTM D 395B) and improved seal force retention. It is a carbon black filled compound utilizing new and proprietary cure chemistry technology with mechanical properties designed for improving sealing performance in both high temperature environments and temperature cycling situations. 7075 joins the family of Kalrez ® Spectrum ™ products designed for the chemical processing industry. To provide even greater sealing performance in dynamic applications where low friction is required, 7075 O-rings have a glossier finish than other Kalrez ® parts. 7075 was specifically developed to be used as an O-ring or custom-sealing component in the chemical and hydrocarbon industries, with an improved thermal resistance that extends maximum service temperature to 327°C (620°F). Kalrez ® Spectrum ™ 7075 offers the enhanced elastomeric properties outlined above while providing a chemical resistance better than the industry standard set by Kalrez ® 4079.

Kalrez® 4079

A low compression set compound for general-purpose use in O-rings, diaphragms, seals, and other parts used in the process and aircraft industries. It is a carbon black-filled compound with excellent chemical resistance, good mechanical properties, and outstanding hot air aging properties. It exhibits low swell in organic an inorganic acids and aldehydes and has good response to temperature cycling effects. A maximum operating temperature of 316oC (600oF) is recommended, with short excursions to higher temperatures possible. This compound is not recommended for use in hot water/steam applications or in contact with certain hot aliphatic amines, ethylene oxide and propylene oxide.

Kalrez® 6375

A carbon black-filled compound for general use in O-rings, seals, diaphragms and other specialty parts specifically for the chemical process industry. This compound has excellent, broad chemical resistance, good mechanical properties, and outstanding hot-air aging properties. 6375 is well suited for mixed process streams because of its excellent resistance to acids, bases, and amines. In addition, it is the suggested compound for use in hot water steam, ethylene oxide and propylene oxide. A maximum service temperature of 275oC (525oF) is recommended.

Kalrez® 1050LF

A general-purpose compound for O-rings, seals, and other parts used in chemical process industries. It has good hot water/steam, excellent amine resistance, and enhanced compression set properties. Maximum recommended service temperature of 288oC (550oF). Not recommended for use in organic or inorganic acids at high temperatures.

Kalrez® 1058

A carbon black-filled compound that has been plasticized with a perfluorinated oil. It is the softest, lowest modulus compound available. Generally, it is similar in chemical resistance to Compound 1050LF; it has an upper service temperature of 260oC (500oF). Typically used in applications that require how sealing force or high extensibility including liquid chromatography septa, seals/seats for relief valves and tubing. Its shrinkage is greater than other Kalrez compounds; therefore, finished parts may differ from standard specifications.

Kalrez® 3018

A carbon black-filled compound similar to Compound 1050LF, except for higher hardness/modulus. This compound offers the best hot water/steam resistance and the best high pressure extrusion resistance. Generally used in oil field and process industry applications where these properties coupled with good amine and general chemical resistance are required. A maximum service temperature of 220oC (428oF) is recommended.

Kalrez® 2035

A carbon black-filled compound that is well suited for selected applications in the finishings equipment, pharmaceutical, semiconductor, and chemical transportation markets. Compound 2035 has excellent chemical resistance exhibiting low swell in organic acids, inorganic acids, esters, ketones, and aldehydes. This compound is suggested for use in the ethylene oxide and propylene oxide applications. It also offers good mechanical properties. A maximum service temperature of 220oC (428oF) is recommended.

Kalrez® 2037

A non-black-filled compound that is well suited for selected applications in the pharmaceutical, semiconductor, and other markets that demand high purity elastomers. Compound 2037 has excellent chemical resistance exhibiting low swell in organic acids, inorganic acids, esters, ketones, and aldehydes. It also offers good mechanical properties. A maximum service temperature of 218oC (425oF) is recommended.

Miscellaneous Kalrez® Properties

Many miscellaneous properties are of interest for specific applications. Some of these are unaffected by compound choice, while others vary with hardness or extensibility. As an example, coefficient of friction typically increases as hardness decreases. In general, miscellaneous physical properties are similar to those of Viton® fluoroelastomer.

Note: Other specialty or custom compounds may be available or developed to applications that require different properties than the above compounds offer: 8375, 8385, 8101, 4001......
