Synthetic Filament
Versatile and high-performance synthetic brush filaments engineered for diverse industrial and consumer applications
Industry-Leading Synthetic Filament Solutions
The Hahl name has been associated with the development, manufacture and supply of filling materials for the brush industry for almost a century: much has changed since the first filaments were extruded more than 50 years ago. One constant remains – our reputation for the highest levels of quality, service and for our capability to satisfy the needs of our customers
Our broad product range is used in the manufacture of all kinds of brushes and brushing tools, used in industry and in the home.
Our Synthetic Filament Range
- PA 6, PA 6.6, PA 6.10, PA 6.12, PA 12
- Polyester PBT, PET
- PP, LDPE
- PPS, PEEK
We operate an extensive standard stock programme covering a diameter range from 0.075mm (.003″) to 2.50mm (.098″) spanning over 100 items which are available in minimum quantities of one box and which can be ordered and shipped at short notice.
Our SBF range is manufactured in 3 locations on 2 continents using own-engineered technology and supplied direct as well through a global sales network with local distribution.
Technical Brushes
Brushes are used in hundreds of different applications to serve all kinds of purpose. Technical brushes made in the form of a strip, flexible and coiled strip, disc, round, roller or twisted in wire are used to wash, treat surfaces, insulate, remove static, convey material and fulfill a multitude of functions either in or in conjunction with other machinery. End applications are found in food, textile, street cleaning, steel, woodworking, glass wash and construction industries, to name but a few.
What Factors Determine the Right Choice of Filament?
Softness/Stiffness: From soft touch to high stiffness
Diameter Capabilities: Range from 0.075mm (.003″) to 3.00mm (.118″)
Filament Profile: Round, oval, x-shape, star shape, flagged – for weight saving or better flow
Crimped Filaments: Aids creation of closed surface on roller brush or helps save material weight
Wet or Dry Applications: All polymers have different levels of moisture absorption affecting performance
Chemical Resistance: Different polymers suit various pH levels and chemical environments
Mechanical and Wear Properties: Filaments require flex capability and resistance to wear for longest lifetime
Temperature Resistance: Most engineering polymers work 80-100°C with PP at 60°C maximum
Specialized Applications
Food Hygiene Brushes: The main polymer of choice for hand held brushes and brooms remains Polyester PBT, which offers excellent wet and dry stiffness, autoclavability and colour fastness. Our products conform to EC directive 1935/2004 and FDA CFR §170-199.
Hairbrushes: Tight diameter control and thermal stability are a prerequisite. Our PA and Polyester filaments are used in many branded hairbrushes throughout the world.
Household Brooms and Brushes: Our long established brand Polymex®, developed to replace PVC as an environmentally friendlier alternative, is produced from 100% recycled Polyester PET. Our Union Mixture creates a high quality broom for indoor and outdoor use.
