Polyamide (PA)

Polyamide (PA) bristles for brushes, painting brushes and brooms

Polyamids are plastics with high melting point and excellent mechanical characteristics, they have high heat stability, so they can be used in wide temperature interval. They have good fatigue strength, damping capacity, slipping capacity and wear resistance. Our products are made of PA 6.0 and PA 6.6 types.

Physical and chemical characteristics

Density: 1.14 g/cm3
Melting point: 210 - 215 ºC
Heat resistance: 130 - 140 ºC

Chemical resistance (at 20 °C)

Chemical resistance of the polyamides is limited, alkalis and mineral acids attack them still in relatively low concentrations.

Water solutions of organic acids (oxalic acid, lactic acid) disintegrate them, too. Most of organic dissolvents do not dissolve them. They have a relatively slight resistance against oxidating agents.

Fields of application

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

Quality alternatives

Standard bundle length: 200; 300; 400; 600 and 1200 mm (bundle lengths different from standard ones are possible according to agreement)

Not oiled


Straight (level)

Profile types

Polyamide bristles are available with the following types



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

Size range


Mechanical characteristics (bristle stiffness and abrasive resistance) of products are to be changed if affected by moisture. As rate of water absorption of material is significant, we treat our polyamide fibres with hot steam in a chamber which is developed specially for polyamide to avoid subsequent deformation.
