Product Description

Brush India Manufacturing Private Limited Fill Material Guide.

A technical brush's performance is entirely dependent on its fill-material, as these are responsible to carry out the brushing action. For this, it is important to properly conceive and analyze while selecting the type of wire. The fill-material can be soft or stiff wire type, either thin or thick filament, highly resistant to high temperature or chemical agents, flexible enough, particularly during bending, deforming and abrading-proof. In many cases, different kinds of wire can be combined and mixed in pre-definite mixing combinations to serve special purposes.

The density and length of the surface of contact are considered when determining the working strength of wires. This concept is applicable commonly in wheel brushes assembly.

During the brushing session, it is important to consider exploiting temperature and the chemical agents concentration, as the operator may utilize the brush completely through several rating performances. Before its use, it is also advised to test the brush in same working condition.
  • POLYESTERE-PET-PBT : This combination is highly stiff, hard and durable.
  • PBT : Polybutile applicable in food industry.
  • POLYPROPYLENE : This has high resistance to chemical agents and low density & resistance to low temperature.
  • NYLON 6 / 6.6 : Stability in dimensions, high stiffness, resistance and low thermal expansion. Used to clean liquid spreading, abrasive surfaces and material.
  • NYLON 6.12 : Tough, abrading resistant and offers humidity and water absorption performance. It is ideal for brushing in water and any other tough brushing environment.
  • NYLON ABRASIVO : This is a stiff and highly resistant material that keeps its shape and performance. Just like NYL 6.12 material, this is resistant to abrading. It is mainly used to deburr plastic material and metals, as well as smoothen and rusticate wooden surfaces.
  • TAMPICO VEGETAL FIBER : This material is ideal for wooden surface treatment, metal polishing and sealing in higher temperature range.
  • HORSE HAIR : This material has excellent brushing, dusting, sealing and wiping effect. It is commonly used for sealing as well as dusting both, laminated and veneered wooden surfaces.
  • PIG BRISTLE : Similar to horsehair, this material is not subjected to electricity and has good sealing, wiping and dusting effect. But, their bristles are stronger.
  • STEELS : Best for deburring, cleaning of metal surfaces as well as common sealing purposes at higher temperatures.
STAINLESS STEEL : This is a rust and corrosion resistant material. This brushing stainless steel along with aluminum, derivative alloys and other material avoids contamination. A contamination, in general, can lead to exploitation of carbon steel wire brushes, as the residues of carbon metal can cause rust. It is strongly advised not to use same kind of brush for scrubbing materials that differ in terms of quality. Also, in an event when carbon steel surfaces are subjected to brushing action, it is imperative to avoid any brush contamination. It is also important to treat stainless steel after brushing treatment, so as to get the stainless steel natural resistance to the corrosion.
