Polypropylene (PP)

Polypropylene (PP) Bristles for Brushes and Brooms

The widely applicable rigid polypropylene (PP) fibres has low density, so they have favourable yield and low costs. Polypropylene does not incept moisture, pollution and smells. Its rigidity is excellent even if it is wet, not fragile and neutral to most dissolvent, oils, acids and chemical agents. It is the most chemoresistant synthetic fibre, that can be produced in UV stabilized version.

Phisical and chemical characteristics

Density: 0,90 - 0,91 g/cm3
Melting point: 171 ºC
Vitrification temperature of the amorphous phase: -15 ºC

Chemical resistance (at 20 °C)

Chemical resistance of polypropylene is excellent.

Fields of application

Household and body-care brushes, brooms, industrial and technical brushes.

Quality alternatives

Possible bundle lenght: 35 – 2000 mm

  • Not oiled: for manual use
  • Oiled: for process with high-speed machines
  • Straight (level)
  • Crimped: we can offer ten types of crimping marked with numbers 1-9 and letter “A”. You can find data of crimping types here.

The amplitude of the crimp can be changed depending on customer demand.

Non flaggable

Flaggable:  if flagging is needed after making brush,

  • min. diameter: 0,23 mm

Flagged: minimum diameter: 0,23 mm,

  • lenght: we can flag fibres with length between 120 – 1000 mm
  • depth: 8 – 13 mm in accordance with demand

Homopolimer: for punching use

Copolimer: for melting (fusing) use

Colours

Our standard colours are given in our colour sample collection. In case of significant quantity is demanded, also different colours can be manufactured.

Size range

Stabilisation

PP bristles with min. diameter of 1.50 mm are treated in chamber with hot air to be perfectly straight.
