List of materials available for the filaments of the bristles
Polypropylene is the most widely used material, it is economical and resistant to acids, its limited return memory means that in the long run it takes unwanted creases. It has good wear resistance, but limited resistance to high temperatures.
Nylon is a very good quality material, it is not very resistant to acids. It has an excellent return memory so the brushes will always be in excellent shape, it is resistant to wear and to temperatures.
Polyester is a high quality material, resistant to acids and has a good return memory. It is wear resistant and extremely resistant to high temperatures.
The so-called “abrasive” material includes those filaments for making brushes for surfaces, it is a material of excellent quality, but not very resistant to acids. It has an excellent return memory and naturally a high wear resistance. It defends itself very well against high temperatures. Its silicon carbide (sand) composition arranged on the surface of the filament is of different grain sizes. It is identified as sandpaper, the lower the number the more abrasive the wire is, vice versa, the higher the number the more it will have polishing functions.
The galvanized metal filaments have excellent resistance to wear and temperatures, are calamitable and have good resistance to oxidation.
The stainless steel filaments have a very high resistance to wear, to high temperatures and do not rust.
Brass filaments are the softest metal filaments used, for example, to remove welding residues from welding and cutting tools because they retain good resistance to high temperatures and resist oxidation.
The carbon filaments are extremely interesting, the filaments are soft and resistant, reach very thin diameters and have a very high conductive capacity to discharge electrostatic charges.
The filaments in Tampico material have a limited resistance to wear, but an excellent resistance to high temperatures.
Animal hair filaments resist wear and temperature very well. Its peculiarity is that it is not subject to the accumulation of electrostatic charges, this makes it particularly suitable for many uses where the electrostatic charge from dragging or rubbing causes problems for machinery or humans.
Information common to all synthetic filaments.
The hardness of a filament is determined not only by its chemical composition, but also by its diameter or section.
The thrust of a brush is due to the force expressed by the flake, or rather by the set of filaments that populate a hole in the brush. The staple strength is determined by the overhang, the diameter of the staple and the density of flakes populating the brush in the unit area. These variables are those values that determine the effectiveness of a brush with respect to another, modifying these parameters can change a lot in the behavior of one brush with respect to another.
The colors available in the catalog are normally: white, black and blue. Other colors can be specially produced.
The filament is normally smooth, but in some cases we can use a corrugated material. The ends of the tuft can sometimes be feathered.
Correct working pressure
Each brush is designed and built to work with a certain pressure. This operating pressure is a few millimeters.
A new brush that works at the correct operating pressure, expresses the best of its potential.
It is commonly thought that increasing the operating pressure increases the effectiveness of the brush, but this is not the case, in fact the exact opposite is achieved. It is not possible to compensate with a higher pressure the effectiveness of a brush made with under-sized filaments.
For this reason it is necessary to turn to serious companies that know how to build a brush according to the operational needs of the situation.
