STANDARD PRODUCTS: compact FKM

regular forms

Main characteristics

  • Standard hardness is 70º shore A but we can also manufacture between 60º and 80º shore A.

  • Black is the usual color, but we can produce green forms too

 

General characteristics

Resistance to mold, sun, humidity and fungus. Work temperature between -30ºC and 240º C. Autoextinguishable. (Doesn’t maintain combustion once the ignition or heat source is retired). Excellent resistance to heat.

 

Electric properties

Presents good electric properties with high voltage.

 

Chemical properties

Good resistance to fuels and aggressive chemicals. Its main use is the extrusion of toric joints. Chemical resistance to ozone, acids and bases (both concentrated and diluted), hydrocarbons (both aliphatic and aromatic) and organic solvents. Resistance to organic and mineral oils and lubricants.

Most standardized FKM cords and derivate toric joints

The fabrication standard of cords or rounded FKM is an extruded profile of calibrated circular section, manufactured in diverse dimensions. JV Group extrudes from 1.7 mm and up to 100 mm, in different roll lengths (25 m, 50 m and 100 m). Depending on the client’s needs, the roll format can vary, and we even manufacture other intermediate diameter measures (2.5, 3.5, etc.) and cut pieces starting from 1mm of length. The due date, although variable, is a maximum of 1 week in roll format, 2 weeks if cut.

Most common diameters are:

Arcade, Industrias J.V. and Elastómeros J.V. produces, starting from a toric profile cut in the desired measure, toric joints whose two endings are glued using cyanoacrylate or Loctite®. We recommend the use of glued toric joints only in static applications. For dynamic applications, we recommend vulcanized joints. These toric joints don’t have development limit and work really good in tightness applications without the need to invest in an expensive mold for its manufacturing, working in valve sealing, bombs, doors, O-ring type seals, stopcocks, tanks, transformers, self-sealing valves, among other applications.

For the toric joints, it is essential that the placement where the joint will act is accurately calculated in shape and dimensions, since the correct functioning of the joints will depend on that.

The dimensions of the toric joint are given by its interior diameter (d1) and its thickness, or the diameter of the extruded cord (d2).

To choose the correct toric joint we have to be aware of the resistance to the fluid to which it has to keep tight against (joint swelling can happen, but never compression), resistance to work temperatures, resistance to wear and deformation and selection of the adequate hardness depending on the pressure it will need to resist. In case of any doubt, please contact with our technical department.

Most standardized diameters of FKM tubes, its flat washers and derivate tubular sleeves

Arcade, Industrias J.V., S.A. and Elastómeros J.V., S.A. produces compact tubing and hoses from an interior diameter of 1 mm and up to an exterior diameter of 180 mm, with wall thicknesses starting from 0.25 mm, provided in different roll lengths (25 m, 50 m y 100 m) depending on the client’s needs. We also manufacture, if needed, other intermediate diametric measures (2.5, 3.25, etc.).

Through this tubing, JV produces FKM washers or flat joints, cut pieces, flexible hoses or tubular sleeves starting from 1 mm of length. Washers are frequently used for proper sealing of the unions of closing elements where tightness is important, and generically in any hydraulic or pneumatic element to avoid fluid leaks because of mechanization malfunctioning in closing areas, even having internal pressures, for example in engines and compressors. This saves a lot of money because it allows the mechanization not to be totally perfect in coupling.

Another common product made from tubing is the inflatable joint. It is widely used as a solution for coupling moving parts, that can be connected or disconnected through the inflating or deflating of the joint. One of its more extended uses is in the area of acoustic isolation.

Also, JV manufactures tubular sleeves with this tubing. They are generally used as a technical solution for fluid transfer, in refrigerating systems, admission, heating and engines. The due date for a FKM hose (given in meters) is 2 weeks, 3 if cut or manipulated. 

 

The most common diameters in tube sleeves are:

Most standardized FKM squares and squared joints

Arcade, Industrias J.V., S.A. y Elastómeros J.V., S.A. manufactures compact, squared FKM cords (extruded profile of calibrated square) both in solid and with perforations, and also with holes between 2 mm x 2 mm up to 80 mm x 80 mm. They are profiles generally used for the realization of squared joints. The joints of square profile are used for static applications such as flanges, covers, pistons, stems, alternative movements, for tightness of axis and rotating joints in movement and specially where toric joints have torsion risks. We have tools of all measures between 2mm x 2 mm and 80 x 80 with possibility to create perforations and internal holes.

 

The most common measurements are:

Most standardized FKM rectangles and

rectangular joints

Arcade, Industrias J.V., S.A. y Elastómeros J.V., S.A. manufactures compact, rectangular FKM profiling and strips or bands (extruded profiles of calibrated rectangular section) both solid and with perforations or holes between 0.5 mm up to 80 mm. 

The most requested bands are:

For FKM rectangular profiles, the JV Group has moving lines that allow the manufacturing of any rectangle. The most common application of this profiles is tightness joints and packaging.

The most used rectangles are:

All this range of FKM articles: cords, tubes and hoses, squares, rectangles, as well as flat joints, round joints or washers, can be manufactured in all types of hardness and bases (compact or cellular) in black and white and meeting regulations and/or special physical and mechanical characteristics. Please consult with our technical department different possibilities such as welded joints, glued joints, inflatable joints starting from a tube or cord (with or without reinforcement) and adhesive on one face or two faces.
