Walnut shell granulate
Product information – blasting media
200 – 450 µm to 1.700 – 2.400 µm
Walnut shell grit is an angular, very soft, organic and iron-free recyclable abrasive produced from cleaned and milled nut shells and fruit kernels. It is particularly well suited for removing surface contamination without attacking the base material, for deburring thermoset plastics, and for matting aluminium and plastic surfaces. Typical fields of application include the blasting of engine components and the restoration of classic vehicles of all kinds. The product is available in a wide range of grain sizes, allowing it to be precisely matched to the required surface treatment. Accelerated by air or liquid, it effectively cleans and polishes materials, removes elastic coatings and deburrs delicate workpieces. Walnut shell grit is derived entirely from renewable raw materials and is therefore a particularly environmentally compatible abrasive.
