Even in the harshest environments, subjected to temperature extremes and harsh chemicals, FKM fluoroelastomers perform extremely well. With that in mind, this rugged rubber is ideally suited for applications requiring hard-wearing O-rings, gaskets and seals. FKM might just be the most durable and high performance rubber material that you’ve never heard of. Here, 360 Industrial Products Co. gives the full lowdown on this impressively versatile fluoroelastomer.

Viton commonly used in O-rings and other moulded or extruded products. This family of elastomers comprises copolymers of terpolymers of tetrafluoroethylene (TFE), hexafluoropropylene (HFP) and vinylidene fluoride (VDF or VF2), vinylidene fluoride (VDF) and hexafluoropropylene (HFP) as well as perfluoromethylvinylether (PMVE) containing specialty polymers. There are four families of FKM polymers, and the fluorine content of these most popular FKM grades varies between 66 and 70%. The main grades are A (Dipolymers of VF2/HFP), which has a fluorine content of 66%; B (Terpolymers of VF2/HFP/TFE), which commonly used for seals or gaskets and contains 68% fluorine; F (Terpolymers of VF2/HFP/TFE), which is used in oxygenated automotive fuels and has 70% fluorine content; and finally specialty types (such as GLT, GBLT, GFLT & FKM Extreme), which are used in automotive and oil exploration applications.

Compared to most other elastomers, FKM is better able to withstand high temperature, while simultaneously retaining its good mechanical properties. Oil and chemical resistance are also essentially unaffected by elevated temperatures. Compounds of FKM remain substantially elastic when exposed to laboratory air oven ageing up to 204°C or to intermittent exposures up to 316°C. FKM grades also resist degradation from a wider variety of chemicals and fluids – including oils, fuels, lubricants and most mineral acids – than any other non-fluorinated elastomer. In layman’s terms, that means it provides the best fluid resistance of any commercial rubber. With its low permeability to such a broad range of substances, FKM is known to deliver exceptionally good performance in oxygenated automotive fuels. The rugged characteristics FKM don’t stop there however. Because they also display good resistance to compression, even at temperatures that would make other non-fluorinated elastomers brittle. It is also especially resistant to atmospheric oxidation, sun, climatic conditions, fungus and mould. Furthermore, FKM has good electrical properties (in low voltage, low frequency applications) and low burning characteristics.

FKM seals are most commonly used with the following media:

We are a leading organization engaged in manufacturing and supplying an optimum quality array of NBR Diaphragms. Offered diaphragms are manufactured by making use of quality approved that is procured from the most honorable vendors of the industry in line with international quality norms. After the production process, we make the offered diaphragms pass a quality test to ensure their flawlessness. Offered diaphragms are available in various sizes, different shapes in natural, neoprene, EPDM, silicon and NBR rubber. Moreover, we provide PTFE laminated rubber diaphragms for valve and pump.

• Effective
• High performance
• Long lasting

EPDM stands for Ethylene Propylene Diene Monomer rubber. EPDM solenoid valve seals are well suited for use with hot waterand steam due to EPDM's excellent resistance to heat. The working temperatures of EPDM is approximately between -10 °C to +140 °C. EPDM is unsuitable for use with most oils and fuels. WRAS approved EPDM diaphragms are also available.

EPDM seals are most commonly used with the following media:

PTFE is known for its high chemical resistance and low friction. For this reason, it is a highly functional material for use in many diaphragm applications, including hygienic and aggressive chemicals.

KEY CHARACTERISTICS: 

• Outstanding chemical resistance

• Extremely low friction

• Soft and formable

• Good bearing and wear properties (bearing

grades)

• Good weathering resistance

• Performs well at elevated temperatures

• FDA compliant grades available

APPLICATIONS:
•Seals and gaskets

• Valve and fitting components

• Pump parts

• Manifolds

• Semiconductor equipment

• Scientific equipment

• Medical equipment

• Chemical resistant tubing

• Bearings and bushings (bearing grades)

• Better height-to-diameter ratio, therefore longer travel
• More efficient seal
• Greater resistance to pressure
• Possibility of using all types of rubber and fabric inserts
• Lower sensitivity and greater hysteresis
• The ply is not positioned at centre, as with the rubber-coated fabric, but on the outside surface. As a result, the differential pressure will always be applied to the side of the rubber.

Disadvantages: Lower sensitivity and greater hysteresis; The ply is not positioned at centre, as with the rubber-coated fabric, but on the outside surface. As a result, the differential pressure will always be applied to the side of the rubber.

Diaphragms, in different materials and with different designs, are employed in the following machineries:

• Pressure regulators
• Flow regulators
• Linear actuators
• Pneumatic servo-mechanisms
• Positioning valves
• Safety valves
• Acceleration pumps in carburetors
• Pressure stabilizers
• Pressure transducers
• Brakes
• Pneumatic switches
• Household hot water regulators
• Dosing pumps
• Waste-gate valves in turbo-compressors

Polyurethanes are a broad class of polymers which have urethane group (-NHCO-O-). Urethane group is formed by isocyanate reacting with hydroxyl groups. Polyurethane is a unique material that offers the elasticity of rubber combined with the toughness and durability of metal. Polyurethane or Urethane has better abrasion and tear resistance than rubber, while offering a higher load bearing capacity. Urethane offers superior impact resistance, provides excellent abrasion and wear properties, while maintaining elastic memory.

Selecting the correct material for your valve diaphragm, (seal), requires an understanding of available materials. Diaphragms are one of the most limiting factors of a valve. Here we explain about the types of diaphragm available.
