Fill Materials for brushes

Proex (X & Y shaped mixed diameter & coloured polypropylene). Excellent sweeping performance either indoors or outdoors, including environments with dampness or high humidity. The X & Y profile section of the project increases the effective monofilament surface sweeping area by over 25%, therefore making it excellent for dust pick-up. Not recommended for very high-temperature applications such as foundries. Our best selling, quality, general-purpose, ‘main broom’ sweeper brush. Good wear life.

Polypropylene. Good sweeping performance either indoors or outdoors, including environments with dampness or high humidity. Not recommended for very high-temperature applications. The abbreviation “poly” refers to Brush Tech’s long life, co-polymer polypropylene. Not as good as the ‘Proex’ version when picking up light dust. However, can be used in below-freezing conditions. Heavy diameters are excellent at picking up large debris. Good wear life.

Nylon. Nylon sweeping performance is less aggressive than poly and performs less well in conditions with moisture or high humidity. Often used on outside rough surfaces or high-temperature environments because of its toughness and excellent long wear characteristics. Can generally be used in foundries sweeping high heat debris up to 150 Celsius. Excellent wear life.

Natural Fibre. Excellent sweeping material for very light dust control and sweeping fine debris, but natural fibre has a relatively shorter wear life when compared to other synthetic materials. Natural fibre must not be used on wet floors. Recommended for sweeping carpets, as natural fibre will not create static. Poor wear life.

Poly & Wire. Poly gives this brush good general-purpose sweeping ability, while the wire provides a light cutting action for removing compacted dirt or mud. Good wear life.

Fibre & Wire provides excellent dust control but has a poor wear life.

Proex & Wire. Proex gives this brush good general-purpose sweeping ability, while the wire provides a light cutting action for impacted dirt or mud. Any main broom containing wire must not be used in either food factories or airfields. The wire fatigues before the brush wears out. Good wear life.

Polyester PBT. Compared to Nylon, Polyester is stiffer with better flick action, lasts as long and performs better in damp or wet conditions, but it is more expensive. Large diameter (over 0.8mm) polyester will start to fatigue in cylinder main brooms after about 120 hours of use. On side brushes fatigue does not occur. Excellent wear life.
