Werner Rumler offers a comprehensive range of mineral blast abrasives in all standard grain sizes. Whether automotive, aerospace or metal fabrication industry: we provide personal and individual advice on the right blast abrasive, the right grain size, hardness and grain shape for your process. All our products are characterised by consistent quality, long service life and precise sieve analyses. Benefit from over 50 years of experience in blast technology – we deliver quickly and reliably throughout Germany and Europe.

Glass Beads round

Product Information Blast Media

1 – 50 µm to 400 – 800 µm

Description: Clear and highly round glass microspheres for use as blasting media in surface treatments
Advantages: Microbeads small, spherically shaped glass beads are the ideal medium for both smooth and efficient surface treatments. glass beads are characterized by a high degree of roundness, purity and clarity. Their shape results in material-friendly impacts leaving the work piece surface intact. The glass material is a clean and neutral medium that does not intermingle with the treated material glass beads do not cause silicosis. They are available in a wide range of grain sizes, which guarantees tailor-made sieving's for the desired surface treatment applications.
Use: Accelerated by means of air and/or liquid, the glass beads are projected onto the surface of a work piece in order to clean, embellish, matten or compact it. A detailed list of the numerous uses is available on request. Blasting with glass microspheres is an economic and environmentally friendly alternative to manual or chemical surface treatments. glass beads offer optimum flexibility; both for the materials to be treated and the effects to be achieved. The beads are appropriate for use with dry or wet blasting equipment.

Product Information Blasting Media

On request

This non-metallic, high-quality synthetic fine blasting medium made of pure aluminum oxide is suitable for the deburring, cleaning, grinding and matting of high-quality materials, including hardened materials.
Due to the addition of chromium oxide, the material has a very long service life and is tougher than white fused alumina. Even after repeated use/circulation, the reusable material remains sharp-edged, achieving a high removal effect with short blasting times

Matting Granulate

Product Information Blasting Media

FEPA F10 to F220

Non-metallic high-quality matting granulate made of pure aluminium oxide. Especially suitable for matting aluminium rims as paint preparation, but also for blasting high-quality materials made of stainless steel, brass, aluminium etc. In the fine grain gradations between F 100 – F 220 this granulate is particularly suitable for the gentle vortex blasting technique. With this process the finest surfaces are achieved, e.g. for processing and matting aluminium rims, decorative blasting of high-quality workpieces, parts and decorative objects.
