PVC monofilaments (polyvinyl chloride) can be used to manufacture brooms and brushes used for cleaning. 


Due to their intrinsic properties, Polypropylene fibres can be used in any product requiring good hardwearing  and a low density value, such as in the industrial brushing and road sweeping sectors, but also in the household brush sector, thanks to their excellent behaviour at high temperatures. 

Polyethylene is the polymeric material with the simplest chemical structure. Its lightness, softness and low bend resistance make PE interesting in applications where there is no need for “consistency”, stiffness or resistance to stress. PE fibres are mainly used in soft brushes for special industrial applications such as the large brushes in carwashes or roller brushes for fruit/vegetable treatment and so on.


Polyester monofilaments are mainly used to produce brooms and brushes when it is necessary to give prevalence to particular specifications such as good resistance to high temperatures, flaggability and softness in thinner diameters. Thanks to its resistance to wear and abrasion, Polyester is also used for the production of industrial brushes and paintbrushes as an alternative to other materials such as Nylon or natural fibres. Two main qualities of Polyester are used in the brush industry:

  • PET (polyethylene terephtalate)

  • PBT (polybuthylene terephtalate) mainly used for tooth and hygienic brushes as PBT matches the HACCP (analysis critical control points) guide lines edited by FDA in USA


Nylon 6 is used in many cleaning products and industrial applications. Its specifications and the ease with which Nylon is processed make it competitive in the production of many kind of brushes.

Nylon 66 filaments have higher specifications, especially as regards resistance to wear and abrasion, and bend recovery. Nylon is used to produce  industrial brushes, paintbrushes, brushes for personal hygiene, etc.

Filaments in Nylon 610/612 feature the highest specifications, especially thanks to their excellent bend recovery and abrasion resistance. They also feature limited water absorption, which affects their elastic properties. For this reason, they are used in toothbrushes, paintbrushes, make-up brushes and various industrial applications.
