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.

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.

Aluminum metal foam is a fully customizable rigid, opened pore three-dimensional network of interconnected solid aluminum ligaments. The aluminum foam has a high strength-to-weight ratio, strong compression strength, and a high surface area per unit volume.

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.

Zirconium carbide (ZrC) is an extremely hard refractory ceramic material that is a gray metallic powder with a cubic crystal structure. It has good high-temperature mechanical properties, excellent electrical and thermal conductivity, a high melting point, and strong chemical resistance. Under irradiation, it demonstrates low neutron absorption cross-section and weak damage sensitivity. Various standard granulations are available below 106 microns. Purities: 99.0% & 99.5%

Silicon carbide (SiC) is a hard, covalently bonded light grey solid that is nearly as hard as diamond. It is a refractory material (high melting point) with excellent thermal conductivity and low thermal expansion. It displays good thermal shock resistance, corrosion resistance, and stiffness. Silicon carbide is a semiconductor.

Electrolytic iron is the purest form of iron, whereby commercial iron has all impurities removed through electrolysis. This electrochemical refining process helps to ensure uniform chemical composition and tight particle size distributions. Cathode deposit is supplied as small, smooth, irregularly shaped iron pieces. Chip from bright annealed and polished high-purity electrolytic iron chips, nominally 3/32” x 3/32” (2.5 x 2.5 mm) approximately 1/64” (400 μm) thick. The chips grade is known for its extremely low sulfur and carbon content and smooth polished uniform chips, which are easy to measure and disperse. Powder grade is available as annealed, unannealed in three different mesh sizes, or kosher certified. Purity 97%+

Carbon is a pure non-metallic element found only in the forms of diamonds and graphite. Graphite is widely used for many applications because of its unique combination of properties. It is slippery to the touch, a good conductor of electricity and heat, is chemically inert, and can withstand high temperatures and corrosive environments. 99% to 99.99% (metals basis)

Diamond Dust is composed of pure carbon. Diamond powder is a super-abrasive and is offered in two categories: synthetically grown and naturally grown. Naturally mined diamond purity is 99+%. Synthetic diamond purity is 99%.
