Non-woven Abrasive Tools

 

 

Material:

Various grades of synthetic fibre and abrasive grit are combined and bonded with special resin, firmly fixing the grit particles to the non-woven fibres. The result is a flexible open structure, with no tendency to clog. The material is self-dressing and suitable for wet and dry processes.
LIPPERT-UNIPOL offers a wide range of materials purchased from selected suppliers world-wide.
Extensive testing ensures that every material is ideally suited to a particular application.

-  light grinding processes
- cleaning
- satin finishing
- light deburring work
on
- steel
- stainless steel
- non-ferrous metals

LIPPROX ® Types available 

Special formulas together with the polymerisation process determine the performance of LIPPROX ® . To cover many requirements, LIPPERT-UNIPOL has developed a complete range of bonding, with various characteristics, increasing in hardness as follows:
LIPPROX® C1 - soft, porous bonding
LIPPROX®C2 - medium hard
LIPPROX® C3 - hard
LIPPROX® C5 - very hard, dense bonding 

To absorb a high level of stock removal (dust, chippings etc.), the following types are recommended:
LIPPROX ® W1 - very open structure, medium hardness LIPPROX®  W3 - open structure, very hard  

(*) max. width may vary depending on diameter and hardness. Minimum ordering quantities apply to widths up to 300 mm. See top of the  page  for materials available and various densities. Large LIPPROX® rollers can be dynamically balanced per DIN ISO 1940-1, G40
