Filling materials

voordelen_top

    The choice of filling materials is an essential decision in the making of effective brushes.
    There are various types of materials. The four most important categories are:

  • Synthetic fibers: Polyamide or Nylon (quality type: 6, 6.6, 6.10 and 6.12), Rilsan®, polypropylene, polyester and abrasive nylon.
  • Natural fibers: Both animal (horse and goat hair, pig bristles, geese and ostrich feathers) as vegetable fibers (Tampico) can be used. These fibers have an antistatic characteristic.
  • Steel wires: Steel (high resistant, copper cover, rust free or moderated), copper and bronze.
  • Special fibers: Wytex®, Pekalon, glass fibers, FRH, carbon fibers etc. are resistant to temperatures up to 200°C, chemicals and mechanical conditions (diffraction and extraction). Do not release any harmful gasses when in fire.

    • The appearance of the filling depends of the style and sustainability a client demands. KOTI offers filling
    diameters in all sorts of diameters, straightened or waved hair and various colours.

    We often develop new types of materials, so do not hesitate to contact us!

Which fiber for which application?

Applications and characteristics of the fibers

 

Synthetic fibers

Nylon 6.6
(Polyamide 6.6)		 This quality type is mainly used for industrial applications. Very resistant to heat and wear.
Nylon 6.12
(Polyamide 6.12)		 Does not retain moisture, better recuperative power than nylon 6.6.
Rilsan Does not retain moisture, very resistant to wear.
Polypropylene (PP) Does not retain moisture, resistant to acid, less resistant to wear than nylon 6.6 and 6.12.
Polyester (PE) Very well resistant to heat, well resistant to wear and does not retain moisture.
Abrasieve nylon For delicate deburring, polishing and glaze finishing.

 

Natural fibers

All natural fibers are antistatic; they don’t generate electricity but do retain moisture.
Horse hair Flexible fibers for brushing lighting (e.g. cleaning plastic strips).
Goat hair Extreme flexible fibers for delicate work.
Pig bristles Firmer than horse hair.
Geese feathers Patinening of wooden Furniture after polishing.
Ostrich feathers Very soft material, mainly used for dusting and polishing car bodies.
Tampico Firmer than pig bristles, mainly used for polishing metal with a polish.

 

Steel wires

Steel Very aggressive fibers, used for removing carbon and burr.
Copper Used for polishing, glaze finishing and offers a good explosion proof conductive power (somewhat lower than bronze).
Rust free steel Used for polishing, glaze finishing and offers a good explosion proof conductive power and is resistant to moisture.

 

Special fibers

Conductive Wytex Synthetic fiber, very high conductive power.
Pekalon Synthetic fiber, well resistant to heat (up to 200°C).
Glass fibers Very resistant to heat, high elasticity power and good recuperative power (also used in the cardboard industry).
Carbon High conductive power, very fragile material.
FRH Self extinguishing nylon fiber, does not release any harmful gasses when on fire or used in areas where safety is the highest priority (public transport).

 

Anti-UV treatment

Nylon or PP Extensive exposure to sunlight can speed up the process of colour fading of the fibers and makes the fibers breakable. This can be avoided by giving the fibers anti-UV treatment.
