Additives for Plastics: Volume 1, State of the Art summarizes the state of the art about additives for plastics, including coupling agents for fillers and plasticizers, as well as colorants, silicas, cellulose fiber, whiskers, and microfibers.
More specifically, the present invention is directed to a biodegradable plastic comprising between about 10% to 60% by weight starch which contains more than 3% intact starch granules; between 30% to 70% cellulose acetate which has a molecular weight ranging from 28,000 to 62,000 Daltons and a viscosity of 3 to 44 seconds; and between 5% and 35% of a plasticizer selected from the group consisting of triacetin, diacetin, monoacetin, ethylene glycol, propylene glycol and glycerol.
Cellulose acetate is the acetate ester of cellulose. It was first prepared in 1865. It was first prepared in 1865. Cellulose acetate is used as a film base in photography , as a component in some coatings , and as a frame material for eyeglasses ;  it is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards .
Bioplastics are plastics derived from renewable biomass sources, such as vegetable fats and oils, corn starch, straw, woodchips, food waste, etc. Bioplastic can be made from agricultural by-products and also from used plastic bottles and other containers using microorganisms.
In truth, acetate film and sheets are a specific type of plastic material called cellulose acetate, which is derived from natural sources like wood pulp and cotton. Acetate as a polymer is not only used for making plastic film, but also for making tool handles, eye-glass frames, and as an component of many medical and food industry products.
Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, and flash string) is a highly flammable compound formed by nitrating cellulose through exposure to nitric acid or another powerful nitrating agent.
Polyhydroxyalkanoate (PHA) plastic uses starch also, typically from corn or sugarcane or beetroot, and it shows up in things like cosmetics bottles. Cellulose-based plastics are made of cellulose, the main component in plant tissues.
The reaction can produce mixed products, depending on the degree of substitution of nitrogen, or the percent nitrogen content on each cellulose molecule; cellulose nitrate has 2.8 molecule of nitrogen per molecule of cellulose.
Cellulose nitrate The 19th-century development that allowed for the nitration of cellulose fibres obtained from cotton linters may constitute the advent of plastics. In 1832 Henri Braconnot, a chemist at Nancy, Fr., prepared a “xyloidine” by treating starch, sawdust, and cotton with nitric acid .
Cellulose and wood fibres are excellent additives for moulding compounds Cellulose and wood fibres have been used successfully for decades to improve the quality of plastics. Cellulose powders and wood flours have been successfully used for decades in moulding compounds.
Cellulose acetate is an amber-colored, transparent material made by the reaction of cellulose and acetic acid or acetic anhydride in the presence of sulfuric acid. It is thermoplastic and easily molded.
Cellulose fiber reinforced PP compounds have potential uses in a variety of structural injection molded parts including bezels, bases, brackets, knobs, handles, lids, and housings for the automotive, appliance, furniture, lawn and garden, sporting goods, and toy markets.
cellulose nitrate (pyroxylin) plastic material in a Group F building shall be stored and handled in accordance with Sections 6504.1.1 through 6504.1.7. 6504.1.1 Storage of incoming material.
Cellulose nitrate was discovered by Henri Braconnot in 1832 (xyloidine) and first commercially produced in 1838 by Théophile-Jules Pelouze as an explosive (nitramidine). As production techniques improved, nitrocellulose was developed as a plastic, especially as a substitute for ivory .
Distributor of plastic materials including ethylene vinyl acetate (EVA) plastic materials & cellulose acetate plastic materials. Available in forms including sheets, rods & tubes & in pre-cut & custom sizes.
Cellulose Acetate Butyrate (CAB), commonly known as butyrate, is resistant to ultraviolet rays, has a lower moisture absorption than acetate and has an extremely high impact strength. Cellulosics, as a group, are characterized by good strength, toughness, and high surface gloss.
Cellulose Nitrate (Celluloid) Properties and Applications. Nitrocellulose (NC), also called cellulose nitrate, is the oldest thermoplastic. It was invented by Alexander Parkes in 1855 and later commercialized under the trademarks Parkesine, Xylonite and Celluloid.
The names cellulose nitrate and pyroxylin are used for the compounds of lower nitration, and the term nitrocellulose is used for the explosives. Cellulose nitrate is the toughest of the thermoplastics.
Cellulosic Plastics - The family of cellulosic plastics includes cellulose acetate, cellulose acetate butyrate, cellulose propionate, and ethyl cellulose Very pure and white cellulose, wood flour from soft or hard wood.
Cellulose nitrate on copper with iron, 65.4 x 94.0 cm (25 3/4 x 37 in.) Yale University Art Gallery. Gift of Collection Sociètè Anonyme. The work’s originally clear plastic components now show extreme signs of degradation, including warping, cracking, crazing and discoloration, which exacerbated corrosion processes in the metal pieces.
