INKUMER EL

Polyurethane Elastomer Inkumer

INKUMER-EL (PU) is a polyurethane elastomer with hardness of 55, 60, 65, 70, 75, 80, 85 and 90 units according to the Shore scale A.

Polyurethane INKUMER-EL products and blanks are resistant to sudden atmospheric changes and crashproof, durable in commercial operation.
It effectively supersedes rubber plates and parts, steel and plastic sheets in various processes for the integrated problem solution of abrasive wear, impact loads, sticking of materials.

APPLICATION

The sheets are used for lining: bunkers, silos, of transport trays, orepasses, tanks, troughs, chutes, the bodies of large-capacity dumpers, excavator buckets, tractor buckets, buldozer blades, wagons, trolleys, other equipment and machinery, etc.

Rods are used for the manufacture of guide fixtures, covers of drive and pressure rollers, and superior wear life of ordinary rubber covers up to 20 times. Blanks in the form of thick-walled tubes are ideal  for covers with press fit for metal rollers. Flaps, bushings, seals, and rings are made from them.

ADVANTAGES

The main advantages of polyurethane INKUMER-EL over lining products from steel, rubber or polyethylene:

  • The exceptionally high resistance of the INKUMER-EL material to shock-abrasive loads increases the service life of the lining. Applying INKUMER-EL instead of lining metal, you are guaranteed to increase the life of the equipment 4 times or more!

  • Prevents the sticking of material due to low friction coefficient of polyurethane INKUMER-EL. Does not require constant cleaning of the working surfaces.

  • Reduction in dusting areas and the absence of welding work in the repair of the gravity-fed equipment.

  • Noise reduction in the production areas.

  • Reduced time and financial expenditures to repair jobs and frequent replacement of the lining material.

The advantages of polyurethane INKUMER-EL over rubber:

Products made of polyurethane are resistant to sudden atmospheric changes and crashproof, durable in commercial operation and have characteristics which are unattainable for conventional rubbers:

  • 2 times higher elasticity.

  • 3 times higher wear resistance.

  • 2.5 times stronger then rubber.

  • High resistance to multiple strains.

  • The ability to work under high pressure (up to 105 MPa).

  • Chemical resistance to many solvents and acids.

  • Increased hardness (up to 95 units of Shore).

  • Temperature range of work from -50°C to +80°C.

  • Resistance to microorganisms and fungi.

  • Vibration and oil-benzine-resistance.

  • Elasticity at low temperatures.

  • High dielectric properties.
