Carbon black (with subtypes acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking in a limited supply of air.
Propylene glycol is a compound which is GRAS (generally recognized as safe) by the US Food and Drug Administration under 21 CFR x184.1666, and is also approved by the FDA for certain uses as an indirect food additive. Propylene glycol is approved and used as a vehicle for topical, oral, and some intravenous pharmaceutical preparations in the U ...
Pentabromodiphenyl ether mixture [DE-71 (technical grade)] – Pentachlorophenol: 87-86-5 Pentachlorophenol and by-products of its synthesis (complex mixture) – Pentobarbital sodium: 57-33-0 Pentosan polysulfate sodium – Pentostatin: 53910-25-1 Perfluorooctane sulfonate (PFOS) 1763-23-1 Perfluorooctanoic acid (PFOA) 335-67-1 Pertuzumab ...
Carbon compounds. Carbon compounds are defined as chemical substances containing carbon. [ 1][ 2] More compounds of carbon exist than any other chemical element except for hydrogen. Organic carbon compounds are far more numerous than inorganic carbon compounds. In general bonds of carbon with other elements are covalent bonds.
Calcium carbonate is a chemical compound with the chemical formula Ca CO 3. It is a common substance found in rocks as the minerals calcite and aragonite, most notably in chalk and limestone, eggshells, gastropod shells, shellfish skeletons and pearls.
Activated carbon. Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area [1] [2] available for adsorption or chemical reactions [3] that can be thought of as a microscopic "sponge" structure (adsorption ...
Filler materials are particles added to resin or binders ( plastics, composites, concrete) that can improve specific properties, make the product cheaper, or a mixture of both. [ 1] The two largest segments for filler material use is elastomers and plastics. [ 2] Worldwide, more than 53 million tons of fillers (with a total sum of approximately ...
n, a polysaccharide consisting of a linear chain of several hundred to many thousands of β (1→4) linked D -glucose units. [ 3][ 4] Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. [ 5]
