The cable desk grommet brush has various specification of material. Different material has different sales price. Generally, it is made of PP or PA filament with/without flame retardant function for your choice.

I suggest to use flame retardant filament to make the cable desk grommet brush which is a cable manager with many cable and electrical wire passing through. Otherwise, when short circuit happen and cause spark, the cable desk grommet brush without flame-retardant will start a fire which cause severe destroy. But with flame-retardant cable desk grommet brush, the fire can be avoided.

AOQUN has devoted to R&D flame retardant filament which has 4 degrees of HB, V-2, V-1, V-0. AOQUN cable desk grommet brush has already reached the UL94 V-0 degree.

The sample of cable desk grommet brush which thickness is between 3 to 13 mm, the burning rate should less than 40 mm/second; less than 3mm, the burning rate should less than 70 mm/second， or die out in less than 100 mm.
