Almond Shell Powder and Granules are natural organic materials that are odorless. They qualify as organic, vegan, and halal and are fully biodegradable.

Amorphous carbons include Carbon Black, Furnace Black, and Channel Black. They are black pigments produced by the thermal decomposition of natural hydrocarbons. These are free and reactive carbons with no crystalline structure. Reade offers furnace black. Nominal purity= 98.5 to 99.6% Available in bead, ground, and powder form with particle sizes ranging from 16 to 280 nanometers.

Apricot, Peach, and Plum Stone Powder are natural organic materials that are odorless. They qualify as organic, vegan, and halal and are fully biodegradable. Fruit stone shells are mostly comprised of insoluble fibers. They are a versatile base material and additive due to their neutral smell.

Avocado stone is a natural organic material with most of the nutrients contained in its large, heavy stone. It is richer in amino acids, vitamins, and soluble fibers than any other fruit or vegetable. Avocado stone has a high antioxidant content making it attractive for many herbal remedies and anti-aging formulations. The powder has a somewhat nutty flavor. Due to its relatively high oil content, it should be eaten and processed in a fresh state.

Bentonite is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Sodium (Na)-montmorillonite or Calcium (Ca)-montmorillonite. Na-montmorillonite has a considerably greater swelling capacity than Ca-montmorillonite. As a swelling clay, bentonite can absorb large quantities of water, which increases its volume by up to a factor of eight.

Corn Cob Grit is an environmentally friendly free-flowing abrasive made from the hard cob. It is used primarily as a vibratory and tumbling media to absorb oils and dirt and to dry parts without affecting the surface of the parts. It is a safe and economical blasting media that can be used on delicate parts. Corn Cob grit is non-toxic, dust-free, long-lasting, reusable, and preserves micro finishes. Typical Physical Properties Hardness: MOH 4.5 Appearance: Granular angular particles Specific Gravity: 1.0 – 1.2 gm/cc

Dolomite or calcium magnesium carbonate (CaMg(CO₃)₂) is derived from limestone. It is a crystalline carbonate mineral with a snow-white or gray color. Dolomite Powder Nominal Chemical Composition: CaO= 30.48%, MgO= 21.77%, Al₂O₃= 0.02%, Fe₂O₃= 0.04%, and SiO₂= 0.30%

Feldspar is a naturally occurring anhydrous, inorganic, igneous rock. A complex aluminum silicate (Tectosilicate) that contains varying amounts of sodium, potassium, and calcium. Feldspar is highly abrasive. Feldspar powder provides strength, durability, chemical inertness, and resistance to wear and can be added to achieve high solids content with low viscosity impact. KAlSi₃O₈ - NaAlSi₃O₈ - CaAl₂Si₂O₈

Halloysite Nano Clay (Al₂Si₂O₅(OH)₄•2H₂O+SiO₂) is an aluminosilicate clay-like mineral occurring in soft, smooth, amorphous masses of a whitish color. It is 50% silica and 50% clay. Halloysite forms naturally occurring nanotubes similar to a grain of rice but considerably smaller and hollow. It shows low electrical and thermal conductivity and strong hydrogen interactions. Significant improvements in thermal and mechanical properties have been reported on the addition of halloysite nanotubes in polymer composites.

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.

Kaolin, Anhydrous aluminum silicate (Al₂Si₂O₅(OH)₄), is a white soft plastic clay with low iron content. It is characterized by high brightness and is non-abrasive with naturally fine particles. It is refractory, remains white after calcination, and is a weak conductor of heat and electricity. Kaolin is hydrophilic and easily dispersed in water.

Reade offers Muscovite Mica mined in the USA. Muscovite Mica is a hydrated silicate of potassium and aluminum, otherwise known as potassium aluminum silicate. KAl₂(AlSi₃O₁₀)(F,OH)₂, or (KF)₂(Al₂O₃)₃(SiO₂)₆(H₂O). It offers flexibility, and toughness, is relatively soft, has a low coefficient of thermal expansion, exceptional electrical properties, and excellent chemical resistance. It can be a reinforcing agent that will impart excellent dimensional stability to molded parts, reduce flammability, and reduce creep.

Nanoclays, also known as Montmorillonite, Bentonite, and Smectite, are non-metallic clays primarily composed of hydrated sodium calcium aluminum silicate. This clay mineral has a 2:1 expanding crystal lattice that allows water to move between the sheets, giving it very plastic properties, as they can swell or shrink as water accumulates or leaves between the layers. Their volume can increase up to six times by water absorption and form stable gels. Reade offers hydrophilic bentonite Nanoclay. H2Al2O6Si

Olive Pits, or stones, are natural materials that are sustainably sourced. They qualify as organic, vegan, halal, and kosher and are fully biodegradable. They have high particle stability, contain no allergens, and have a relatively homogeneous particle shape. They are a rich source of carbohydrates and easily digestible fibers.

Rice Hulls are a recycled resource. They are the hard protective coverings of grains of rice. In addition to protecting rice during the growing season, rice hulls can be used as a building material, fertilizer, insulation material, or fuel. Rice hulls are part of the chaff of the rice. Rice hulls are buff-colored to a light brown meal consisting primarily of the outer covering of the rice. It contains no oils.

Smectite, Magnesium Aluminum Silicate products are water-washed smectite clays that serve as suspension stabilizers, emulsion optimizers, and rheology modifiers. The powder is light tan.

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.
