Aramid Fiber
Aramid fiber filament
Aramid is an aromatic polyamide fiber family known for strength and heat resistance. In brushes it is used for hot cleaning where ordinary polymers would melt, such as barbecue grill brushes. Para- and meta-aramid grades differ, so the grade is matched to the job.
What is aramid fiber?
Aromatic polyamide fibers, about 12–15 µm across, with a density of 1.44 g/cm³ and tensile strength of about 2.8–3.6 GPa. They do not melt; they decompose above about 450°C. Para-aramid is stiff and very strong; meta-aramid is more textile-like and heat-resistant.
Where is aramid used?
In our range, in the barbecue grill cleaning brush, which cleans hot grates without the wire-bristle risk of steel fill, and as the Cornex (meta-aramid) option on the PPS/Cornex high-temperature brush. More broadly, aramid fill works on hot surfaces where nylon would melt.
How hot can an aramid brush run?
The fiber takes far more heat than the brush can: up to about 200°C is cited for aramid fill, and assemblies are quoted at about 180–220°C. The block, binder and holder set the real limit.
Where does aramid fall short?
It costs more than common fills, it is less springy than nylon, and its moisture response and compatibility with binders depend on the grade.
Aramid or PPS?
PPS works to about 200°C as a monofilament fill and is the usual choice for oven bands and hot molds. Aramid fiber goes as high or higher in assemblies and does not melt, which suits very hot, intermittent contact.
What should you tell us?
The surface temperature and contact time, the deposit, and the brush form, so the fill, binder and body are all chosen for the heat.
Questions buyers ask about Aramid Fiber
Why use aramid on a grill brush?
It takes the heat of a hot grate without melting and avoids loose steel bristles.
How hot can an aramid brush get?
Brush assemblies are quoted at about 180–220°C; the fiber itself decomposes only above about 450°C.
Aramid or PPS for a hot brush?
PPS for continuous work up to about 200°C; aramid for very hot, intermittent contact.

Share what the brush works on, the temperature and chemicals it meets, the form you need — strip, disc, roller or hand brush — the quantity and a drawing or photo.
We reply to every request within 24 hours, with a quotation or with the questions we need answered first. If the brush can be made on our existing tooling, we make the sample directly. If it needs new tooling, we quote a sample fee and a tooling fee, and the sample fee is credited against the bulk order. Need an NDA first? We sign yours before you send drawings, and the files you send are never shown to other customers.
