The PLANTEX® flap disc is patented and made in Germany.

The development of the new PLANTEX® high-tech compound has resulted in the production of the first flap discs in the world with a backing plate made of natural hemp, with polypropylene used to bind it.

This new composite material (hemp and polypropylene) minimizes pollution from production to waste disposal. Even the polypropylene binding material combusts to approximately 1% carbon when disposed of by thermal methods, producing almost zero residue. Polypropylene is physiologically safe and is used in automotive engineering (interior) and medical technology for common items such as syringes, cannulae and infusion bottles. As a result of its fiber structure, the hemp fiber offers excellent tearing strength values. The superior strength values of this high-tech compound are achieved through a patented new treatment (“impact method”) for hemp fibers.

Hemp fiber high-tech compound is an almost ideal base material for flap disc backing plates – it is flexible, heat-absorbent (for low grinding temperatures), very easy to trim, safe to use and easy to dispose of. The cavities of the hemp fiber structure, in conjunction with polypropylene, have a highly insulating, damping and noise-reducing effect, thus enhancing the safety features of the discs.

The high-tech compound material used for the PLANTEX® flap disc is perfectly safe. The backing plate is trimmed automatically during the grinding process or can be trimmed manually using cutting tools. The CO2 and energy balance are also impressive. During its growth, 1 ton of hemp converts approximately 2 tons of carbon dioxide into oxygen by means of photosynthesis. Hemp, therefore, plays a beneficial role in counteracting the greenhouse effect.

Trimming with cutting tools produces soft, harmless chips that can be disposed of as domestic waste (smell is similar to wood chips). Thermal disposal incinerates without residue, apart from 1% carbon.

Safer working conditions

  • No fiberglass, no mineral fibers, no epoxy resin
  • Easy to trim, safe to use, easy to dispose of

Earth friendly

  • Minimizes pollution, from production to disposal
  • Hemp plant counteracts greenhouse effect

Competitively Priced

  • Lower cost of production
  • Superior service life; 100% utilization

Other Features

  • Superior material abrasion and service life due to the discs’ springy elasticity and 100% pure zirconium.
  • Adjusts better to the surface of the workpiece during grinding.
  • Absorbs vibration and noise due to its high fiber content.
  • Heat-absorbent high-tech compound (with hollow fiber insulation) reduces the temperature during grinding.
  • High shape stability while maintaining elasticity.
  • High-tech compound is resistant to most chemicals.
  • Made of a sustainable raw material – protects valuable natural resources.
  • The backing plate can be disposed of safely and easily (polypropylene binding combusts to approx. 1% carbon).
  • Hemp provides good energy and CO2 balance.
  • Outstanding value: PLANTEX® costs no more than a medium-quality conventional flap disc.

The fiber substrate of the PLANTEX® high-tech compound gives it absorbent, spring-like properties that enhance grinding performance. This flexibility provides a greater contact surface area with the workpiece (more grit is used) that results in more material being abraded. The material removal capacity is therefore higher. The larger contact surface area also dissipates more heat, making the grinding work cooler – the workpiece does not suffer smearing and the abrasive fabric does not burn.

Plantex® Flap Discs


Grinding down to the last fraction of an inch

The backing plate used on PLANTEX® flap discs reduces in diameter automatically during grinding. It can also be trimmed with cutting tools, a process that is simple and straightforward. The PLANTEX® flap disc can be used down to the last flap of the abrading fabric – and saves you money in the process!
