Description

Silicon Carbide Abrasive Nylon Polyamide PA612 Bristle Fiber Wire Filament

Abrasive Nylon Brush Filaments:

Abrasive nylon Brush filaments are made of nano-particle modified nylon as carrier and 36~1000 mesh abrasive particles such as SIC, AO, and Diamond grinding dust. The hot melts from the above are extruded to form abrasive nylon filaments that are strong and heat resistant under wet or dry conditions.

Application:

Main applications are devices for workplace deburring, grinding, and polishing of the surfaces of steel, stone, and other materials. Also useful for general surface treatment.

Property Comparison Of Grit:

The most popular abrasive filaments are SIC and AO filaments. SIC abrasive is generally the best choice for the most of the applications. AO is suitable for precision polishing and soft surface. Basically, every industry has its own common-used abrasive filament. For detailed questions, please do not hesitate to contact us for consulting. It would be more helpful, if you can send us some samples for analyzing.

Silicon Carbide (SIC)

Common used abrasive grit is silicon carbide aka SIC grit, which is produced in a resistance type electric furnace with petroleum coke, quartz sand and other materials. SIC is an extremely hard black insoluble crystalline substance. It is used as an abrasive and heat-refractory material and in single crystals as semiconductors, especially in high-temperature applications. Its micro hardness is HV3100-3280, stiffness and hardness is higher than White Alumina. SIC abrasive filament can be widely used to produce industrial brushes for steel, textile, PCB cleaning, stone polishing, and other grinding applications.

Aluminum Oxide (AO)

AO is a brown crystalline substance that is electrically fused in an arc furnace from a mixture of bauxite at high temperature. The main chemical compound is Al2O3. Its micro hardness is HV1800-2200. And comparing to SIC, AO has less hardness but better toughness. AO abrasive filament is suitable for soft surface and precision work condition, such as: to process copper, aluminum, furniture, and precision parts.

Diamond (DM)

Diamond is the hardest substance found in nature with sharp cutting edges and corners, superior self-sharpening property, and high toughness. The grinding ability is 4 times better than SIC and 10 times better than AO. Due to its expensive price, DM abrasive filament has only been used for super hard material and industry with high added value: such as wolfram steel, silicon plate, expensive jewels.

PA612Abrasive Nylon Brush Filament:

PA612 abrasive nylon brush filament is high-class filament with superior performance such as: low water absorption, high durability, better bend recovery, and more toughness.
With a melting point of 210℃ and a heat distortion temperature of 180℃, PA612 abrasive nylon filament is suitable for short-time surface finishing. However, under work conditions with high wheel speed and high pressure, it is better to use cooling system to avoid heat fusing, heat ageing issues and to increase the lifetime of PA612 abrasive nylon filament.
