Sisal

The natural fiber of the Agave plant, grown in South Africa and South America, is a cost-effective and robust natural fiber for metal-polishing, which has become material of choice due to its qualities in the polishing process.

By using only first class, long sisal fibers for matting and braid, the quality of the sisal polishing tools is exceptional and guarantees a long life.

Fine Grinding and Pre-Polishing

Sisal buffing with the appropriate compounds would be the next step of the polishing process, after grinding with abrasive belt grits of 240 for non-ferrous metals and grit 280 for stainless steel. Pure cotton buffs would be hard pressed to do this. This conversion from abrasive belt grinding to sisal buffing at an early stage is economical and cost effective. A good industrial finish will be achieved but no mirror finish. Finer, more shining surfaces can be achieved by using sisal/cotton combinations, instead of pure sisal matting or sisal braid. For certain operations this can be the final step, without colouring with cotton. For this operation, cutting compounds are used.

45° Degree Material Cut

The 45° sisal weave cut on the circumference of the polishing buff minimises buff wear and dust production. No buff fraying or tearing out of the material occurs and the tips of the sisal can work on the object being polished. This results in optimal and thorough pre-polishing.

Recommended Circumference Speed

Sisal buffs are most ecconomically used at running speeds of 30 – 45 m/sec.

Compounds

Sisal buffs are used with aggressive grinding and pre-polishing compounds.

Suggestions for the Optimal Choice of Sisal Brushes

In the case of flat metal components, the buffs and brushes should be as hard as possible, for example:

C1/K: hollow-ware, steel, inox steel

C10/K: hollow-ware pouring lips, cooking pots, fittings, household handles

C13/K: steel tubes, automobile parts, cooking pots

C20: hollow-ware, flat surfaces

More flexible brushes are used for profiled components, for example: C3/KU: silver-polishing, cutlery in general C4/KU: cutlery, metal sheeting, sinks C8/K: cutlery, handles C11/K: knife blades, paint-scrapers

Impregnations

The choice of the most appropriate impregnation is determined by the application, the requirements of our customers and our experience.

The correct impregnation increases longevity of the buff and enhances the polishing effect. This in turn results in cost savings on polishing buffs and compounds. A 50-100% increase in longevity is possible. All our impregnations are environmentally friendly.

Through the years of experience and continuing innovation we have developed a number of exceptional impregnations, with varying properties: fat content, stickiness, softness or high density, as can be seen below.
