Strip brushes – Special types

We refer to our 10 strip brush types with metal backing widths ranging from 1.8 mm to 13.5 mm as special types. These can be manufactured in countless variations according to your specifications. We offer the following selection criteria:

– All types of fill materials, such as natural bristles, animal hair, plant fibers, wire, and synthetic bristles
Profile material made of galvanized steel, stainless steel (1.4301, 1.4571), or brass strip
Various fill heights (free fill material length)
Delivery lengths ranging from a few centimeters to the maximum transportable length

The strip brush Type 60 is primarily mounted in two-part half rings for installation on cylindrical bodies with diameters of 80 mm, 100 mm, and 102 mm, and is thus used as a roller brush.

Special holders are available for mounting strip brushes Type 25 and Type 40.

Fill material

The fill material we use for your brushes depends on your application, industry, and product. Do you have questions about fill materials? Feel free to contact us.

Brush construction
Type of fill material	Fill material	Properties
Synthetic fibres	PP (Polypropylen)	Polypropylene, acid-resistant, smooth or crimped, colors available on request. Diameter 0.10 – 1.00 mm.
Synthetic fibres	PAP (special bristle for wet applications based on PP)	Special bristle for wet applications based on polypropylene, offering longer service life due to acid resistance at high temperatures; available in smooth or crimped versions, colors on request, diameter 0.15 – 1.00 mm.
Synthetic fibres	PBT (Polyester)	Polyester, smooth or crimped, colors available on request, diameter 0.20 – 3.00 mm.
Synthetic fibres	PA 6.6 (Polyamid)	All polyamid qualities have strong recovery properties. PA 6.6 is the filament with the highest rigidity in dry application before PA 6.12 and PA 6. In case of wet use PA 6.12 ranks before PA 6.6 and PA 6 because of the lowest water absorption.
Synthetic fibres	PA 6.12 (Polyamid)	Polyamide, smooth or crimped, colors available on request, diameter 0.08 – 3.00 mm. All polyamide grades are characterized by excellent recovery properties. In wet applications, PA 6.12 offers the best stiffness due to its minimal water absorption.
Synthetic fibres	KBL (PA-based, alkali- and temperature-resistant)	Special bristle based on polyamide, highly resistant to alkalis even at high temperatures; available in smooth or crimped form, brown color, diameter 0.08 – 1.50 mm.
Synthetic fibres	HCB (high-temperature and chemical-resistant)	High-temperature resistant (up to max. 200 °C) and extremely chemical-resistant special bristle, smooth, colors available on request, diameter 0.20 – 0.60 mm.
Synthetic fibres	PE (Polyethylen)	Polyethylene, smooth, slotted or unslotted in X-profile, colors available on request, diameter 0.08 – 1.00 mm.
Synthetic fibres	CON (electrically conductive special bristle)	Electrically conductive special bristle (up to 5 × 10 kOhm/cm²) based on polyamide, smooth, black, temperature resistance up to 100 °C, Ø 0.13 mm. For large order volumes, the following bristle diameters are also available: 0.21 mm, 0.41 mm, 0.52 mm, and 0.64 mm.
Wires	INOX (V2A wire, stainless and acid-resistant)	Stainless and acid-resistant steel wire, smooth or crimped, material no. 1.4301 / 1.4310, diameter 0.08 – 1.00 mm.
Wires	TRD (special wire, high-temperature resistant)	Special wire, high-temperature resistant up to 1350 °C, crimped, diameter 0.30 – 0.50 mm.
Wires	RFH (corrosion-resistant specialty wire)	Corrosion-resistant specialty wire, resistant to process steam up to 650 °C, available in smooth or crimped form, diameter 0.30 – 0.50 mm.
Wires	INOX (V4A wire, stainless and acid-resistant)	Steel wire, stainless and acid-resistant, smooth or crimped, material no. 1.4401 / 1.4571, diameter 0.08 – 1.00 mm.
Wires	STD (steel wire, natural hard)	Steel wire, natural hard, crimped, diameter 0.06 – 0.80 mm.
