Material
Antistatic PBT Filament
Functional polyester filament
Antistatic PBT is PBT filament with an antistatic or conductive additive. It combines PBT's low water uptake and stable wet stiffness with static control, which suits electronics cleaning brushes and anti-static strips on food and packaging lines. The additive can change the base properties, so the grade is confirmed.
Datasheet values
- Filament diameter
- Set by supplier capability and required ESD/contact performance
- Electrical behavior
- Compound and humidity dependent; validate surface/volume resistance for the selected grade
- Water absorption
- Low for base PBT but grade dependent in antistatic compounds
- Temperature use
- Confirm the actual antistatic PBT filament TDS
What is antistatic PBT?
A PBT polyester filament compounded with an antistatic package. It is drawn from about 0.03 mm to 1.0 mm, sits around Shore D 80–90 and takes up about 0.05–0.25% water. Its resistance depends on the package, humidity and the finished brush.
Where is it used?
In our range: anti-static strip brushes for food and packaging lines, keyboard cleaning brushes and earbud and charging port cleaning brushes.
Why antistatic PBT instead of conductive nylon?
Because it keeps its stiffness when wet, takes hot washing better and suits washdown lines, where a nylon carrier would soften. For dry electronics work, either can serve; the resistance range and cleaning conditions decide.
How hot can it run?
Data quote about 120–140°C continuous and 160–180°C peak, but additives change the base polymer, so the selected grade is confirmed.
Where does it fall short?
Electrical behavior depends on the additive, humidity, grade, filament geometry and process. Like any static fill, it needs a grounded holder, and a claim about ESD protection needs testing on the finished brush.
What should you tell us?
The resistance range, the cleaning and washing conditions, the parts or line, the holder and ground point, and any food-contact standard.
Questions buyers ask about Antistatic PBT Filament
Why use antistatic PBT instead of conductive nylon?
It keeps its stiffness when wet and takes hot washing better, which suits washdown and food lines.
Does antistatic PBT need grounding?
Yes. Like any static-control fill, it needs a grounded holder to carry charge away.
Can antistatic PBT strips be used on food lines?
They are used on food and packaging lines. Send the food-contact standard you buy to, and the materials are chosen to it.
