Walnut Media

Manufacturer: Cutting Edge Supply

Availability: Usually ships within 24hrs from the CES Warehouse

Walnut shell grit is the durable, fibrous product made from ground or crushed walnut shells. Walnut shell can be used as a blasting media, tumbling media, and deburring media. Walnut shell is also used in many beauty products, toys, winter tires, and more! Walnut shell grit is extremely durable, angular and multi-faceted, while still being soft enough to not mar base materials. Walnut Shell is about a 3.5-4 on the Mohs Hardness Scale. Walnut shell blasting media is a great alternative to using sand because it does not cause silicosis and is much more health-friendly.

This Medium Coarse Walnut Shell is a 12-16 Mesh. Most commonly used for blasting, tumbling, deburring, deflashing, polishing (Brass, copper, semi-precious metals), molding plastics, scale models, filtration systems, and fillers for stuffed animals.

Cleaning/Blasting with walnut shell blasting works extremely well if the surface of the substrate under its coat of paint, dirt, grease, scale, carbon, etc. should remain unchanged or otherwise untouched. Walnut shell grit can be used as a soft aggregate in removing foreign matter or coatings from surfaces without etching, scratching, or marring cleaned areas.

When Walnut shell is used correctly and with the correct machinery, it can be highly effective. Some of the common blast cleaning applications include stripping auto panels of paint, jewelry polishing, cleaning motors, deflashing plastics, cleaning delicate molds, and watch polishing. When used as a blast cleaning media, walnut shell grit removes paint, marker, burrs, and other flaws in plastic and rubber molding, aluminum and zinc die-casting. Walnut shell has the ability to remove paint, graffiti, and other markings from walls building and artifacts. Walnut shell can replace sand in restoration of buildings, bridges, and outdoor statuaries. Walnut shell is also used to clean auto and aircraft engines and steam turbines. Walnut shell can also make an old log cabin look like new again!

Walnut shell is extremely safe for the environment. At Cutting Edge Supply we have extra treatments performed before we sell our product to ensure its quality, safety, and durability. Walnut Shell can preserve gel coats, primers, and the base color while removing the top layers of paints. While blasting walnut shell you can also remove imperfections or contaminates from different surfaces without scratching, pitting, or maring the substrate material. 

The Walnut shell media is extremely durable, reusable, and biodegradable and reduces the time of finishing. It preserves micro finishes and prevents the issue of silicosis as it is silica-free.

Walnut Shell can also be used to restore historical items, remove paint from walls, deburr metal, polish jewelry, can be used as a reptile bedding, be used as a stuffing in toy animals, be used as an additive to face washes and body washes.
