Walnut Shell Powder

Crushed walnut Shell products including grains, flour, and powder, are biodegradable, non-toxic, and environmentally safe. They qualify as vegan and halal. The material is organic and has a harmonious light brown color and a neutral smell. It is the most common type of soft abrasive for industrial use.

English Walnut Shell Scientific Name: Juglans Regia
Black Walnut Shell Scientific Name: Juglans Nigra
Typical Applications

Walnut shells are an effective natural abrasive in sandblasting, polishing, and cleaning of hard materials such as metal, carbon fiber, concrete or hard plastic, without the need for additives. It is also a bio-ingredient for hygiene products, especially with surface cleaners.

Walnut Shell Flour has applications as a filtration media used to remove heavy metals, oil, or grease. It also has uses to separate fluids and as a filler of surface coatings, filler for reinforced plastics, and as an additive in industrial ceramics. Walnut shells can also act as a carrier for pesticides and herbicides and as a base powder and binder for fertilizers.

Walnut shell powder has cosmetics applications, mainly as an exfoliant; however, walnut shell powder can cause allergic reactions.

Packaging Options

The standard shell packaging is bagged in 50-pound 3-ply paper bags. Forty bags are normally stacked on a 40″ x 48″ four-way hardwood pallet. Packaging options include 250-pound fiber drum, 1,000-pound box, and a 2,000-pound mini-bulk bag.

Classification

Walnut Shell Media / Walnut Shell Grain TSCA (SARA Title III) Status: Not reportable under SARA 313. For further information, please call the E.P.A. Office of Chemical Safety and Pollution Prevention (OCSPP) at 202-564-2902

Sustainable Qualities

Walnut Shell Powder and granules are a sustainable material used in various applications such as abrasives, filters, and cleaning products. These materials are a byproduct of the food industry and are made from the shells of walnuts after the edible portion has been removed. The shells are ground into a fine powder or granules, providing an effective and eco-friendly alternative to synthetic abrasives or chemicals. Using these shells as a raw material for products helps to reduce waste and promotes a circular economy.
Using Walnut Shell Powder and granules in various applications can reduce dependence on non-renewable resources and minimize environmental impact. These materials are biodegradable, non-toxic, and sustainable, making them a responsible choice for a wide range of applications. The use of Walnut Shell Powder and granules also supports the circular economy by promoting the use of waste materials as raw materials, reducing waste, and conserving resources.

View Open Cell Metal Foam
Open Cell Metal Foam
Open cell metal foam, also known as reticulated foam, features 100% open cells with a homogenous structure. The open cells provide a path through the foam in any direction, allowing gas and liquids to pass at control flow rates and buffer pressure. Open foams have high surface area-to-volume ratios which offer large heat transfer rates. They are lightweight, with high compressive strength, stiffness, energy absorption, and low specific weight. Specific properties and applications vary based on foam material. The most popular open-cell metal foam products are Aluminum and RVC foam.

View Hemp Fiber
Hemp Fiber
Hemp Fiber (Bast Fiber) is a high-yield commercial fiber crop that grows from seed. Hemp stalks are harvested for their fibers and grow on the outside of the plant’s stalk, similar to the bark of a tree. Hemp fibers are advantageous as they are flexible, have low density and abrasiveness, and have mechanical properties comparable to glass fiber. There is also quantitative and qualitative homogeneity from one harvest to the next. Degummed Hemp Fiber is processed to remove lignin and pectin, so separated fibers are finer, softer, and more absorbent. Size ranges from ½ inch to 5 inches. Hemp Hurd is derived from the core of the hemp stalks and is also referred to as hemp shives. It looks similar to wood chips. It is porous and absorbent and naturally resistant to mold and bacteria. Raw Long Hemp Fiber is right from the stalk, non-processed, and uncombed with slight separation of fibers. Fibers range from 24 to 72 inches. Combed Hemp Fiber, also known as plumber's hemp, is untwisted and combed. Fiber length ranges from 4-5 inches long.
