Diatomaceous Earth (DE)

Diatomaceous earth, also known as Diatomaceous silica (SiO₂*nH₂O), is the fossilized remains of tiny, aquatic organisms called diatoms that have accumulated, creating silica deposits. DE has high absorption, low bulk density, and high brightness. There are two primary types of diatomaceous earth deposits – saltwater and freshwater. Saltwater DE is commercially processed in the United States and primarily used as a filter aid. Freshwater DE is ideal for agricultural uses because it typically has a low crystalline silica content (amorphous), is highly absorptive, and is an ancient pest control agent. As awareness of and concern about chemical pesticides grow, diatomaceous earth has increased interest as a non-toxic and natural alternative. It is also seen as a natural anti-parasitic by farmers and ranchers.
Typical Applications

DE have been used in hundreds of industrial and agricultural applications. Current applications have DE being used as a filtration aid, mild abrasive in products including metal polishes and toothpaste, mechanical insecticide, absorbent for liquids, matting agent for coatings, reinforcing filler in plastics and rubber, anti-block in plastic films, porous support for chemical catalysts, cat litter, a stabilizing component of dynamite, a thermal insulator, and soil for potted plants and trees as in the art of bonsai.

Sustainable Qualities

Diatomaceous Earth is a naturally occurring, organic material mined from fossilized diatoms’ remains. This material is sustainable as it is a naturally occurring mineral that is biodegradable, non-toxic, and renewable. It is also highly effective as an absorbent, filtering agent, and abrasive material, making it ideal for a wide range of applications, such as water filtration, pet litter, insecticides, and polishing agents.

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 Carbon Nanotubes
Carbon Nanotubes
Carbon nanotubes (CNT) are tubes made of carbon atoms with nanometer diameters. Reade supplies a variety of carbon nanotubes. While many specific properties of CNTs are type dependent, in general, carbon nanotubes have high electrical conductivity. They have good thermal conductivity along the tube axis that is comparable to diamonds while exhibiting elastic, flexible, stiff, tough, and strong fibers while maintaining the chemistry of carbon molecules and being free of molecular defects. This carbon chemistry allows strong Van der Waals attraction which leads to spontaneous self-assembly and roping of many nanotubes, which may be important in certain applications. Single-wall carbon nanotubes (SWNT) are an intermediary allotrope of carbon between fullerene cages and flat graphene. Double-wall carbon nanotubes (DWNT) are similar to SWNT but are more resistant to chemical attacks. Multi-wall carbon nanotubes consist of multiple rolled layers of graphene. Dry powder form and dispersions available.

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.
