 Polyethylene (PE) offers distinct advantages for food-grade brushing:Inherently Inert: PE does not react with food acids or oils and won't impart any taste or odor. Moisture Proof: It absorbs virtually no water, preventing bacterial growth and maintaining its properties in wet environments. Low-Temperature Flexibility: It remains flexible in cold wash water, ensuring effective and gentle cleaning of delicate produce. Excellent Chemical Resistance: It withstands common food-grade sanitizers and cleaning solutions.

Yes, absolutely. Safety is our top priority. Our PE filament is manufactured from raw materials that are fully compliant with major international food safety standards, including the U.S. FDA and EU Regulation 10/2011. This guarantees that the filaments are food-safe and suitable for direct contact with fruits and vegetables during the washing and brushing process.

Despite its durability, PBT is a non-abrasive material. We engineer our PBT filament to a specific stiffness that provides enough scrubbing power to effectively remove dust, grime, and bird droppings, but is soft enough to be completely scratch-free on the delicate glass and anti-reflective coatings of solar panels. This ensures optimal cleaning without damaging the valuable asset.

PBT filament is uniquely suited for solar panel cleaning rollers. Its most critical advantage is exceptional hydrolysis resistance, meaning it does not absorb water and lose strength or stiffness when constantly exposed to water and cleaning agents. Additionally, PBT has excellent resistance to ultraviolet (UV) radiation, preventing brittleness and failure from sun exposure, which is paramount for outdoor, automated systems.

The higher flexibility of PA6 compared to PA66 allows the brush filaments to bend and adapt to the shape of the workpiece. This ensures that the brush maintains consistent contact and pressure across irregular surfaces, such as welded seams, castings, or tubular structures. The result is a more uniform finish without missed spots or uneven wear on the brush.

PA6 filament strikes a perfect balance for many surface finishing tasks. It offers good abrasion resistance, sufficient flexibility to conform to contours, and is more cost-effective than PA66. This makes it an ideal, all-around workhorse for applications like removing light rust, dirt, and scale from metal surfaces, cleaning conveyor belts, and preparing surfaces for painting without the expense of premium filaments.

Absolutely. Customization is key to effective deburring. We offer our PA66 filament impregnated with various abrasives, including silicon carbide (SiC) for hard metals and aluminum oxide (AlOx) for general purpose use, across a range of grit sizes. This allows you to select the perfect combination for your needs, from coarse, rapid material removal to fine, finishing blends.

PA66 (Nylon 66) possesses higher tensile strength and superior heat resistance compared to PA6. This robust foundation allows the filaments to be effectively loaded with abrasive grains (such as silicon carbide or aluminum oxide). The combination of the durable PA66 filament and the embedded abrasive creates an aggressive cutting action that quickly removes burrs, flashes, and sharp edges from metal parts after machining or casting.

The polymer structure of PA612 is inherently less abrasive than other nylon variants like PA6 or PA66. Furthermore, its smooth filament surface and high purity mean it will not embed hard particles that could act as abrasives. This makes it the safest and most effective choice for polishing sensitive surfaces like optical lenses, touchscreens, and automotive glass.

PA612 (Nylon 612) is considered the premium material for glass polishing due to its unique properties. It is exceptionally pure and can be manufactured to very consistent, fine diameters. This, combined with its optimal flexibility and low abrasiveness, allows the filaments to remove microscopic imperfections and buff the surface to a high-gloss, scratch-free finish without causing any damage to the delicate glass.

While all painters can appreciate the benefits, professional painters and serious DIYers working on large, smooth-to-slightly-textured surfaces (like walls, ceilings, and fences) will see the greatest gain in efficiency. The reduced weight and increased paint load mean less dipping, less arm fatigue, and a faster, smoother workflow, leading to higher productivity and a superior finish.

Not at all. BrushMake's hollow PET filament is specifically engineered to overcome this challenge. We maintain an optimal wall thickness that provides exceptional resistance to collapsing under pressure while keeping the filament lightweight. This ensures the brush remains durable and effective throughout its lifespan, even when working paint into rough surfaces.

The hollow structure is a game-changer for paint capacity. Each filament's internal cavity functions like a tiny reservoir, using capillary action to draw in and hold a substantial amount of paint. This dramatically increases the brush's overall paint loading capacity, allowing painters to cover larger areas in a single dip, which improves efficiency and promotes a more consistent application.

Yes, this is one of its key strengths. The increased stiffness and abrasion resistance of a blended filament (like PET/PBT) allow the brush to work paint into uneven surfaces, such as stucco, weathered wood, or concrete, without the bristles bending excessively or wearing down quickly. It is an excellent choice for exterior painting and other heavy-duty tasks.
