Cellulose Acetate Paper Uses

For business applications this acetate film is most often used in an a4 letter format measuring 8 5 by 11 inches and laid on bulb powered overhead projectors to emit a projected image onto a large surface.

Cellulose acetate paper uses.

Nitrocellulose is widely used as support in diagnostic tests where antigen antibody binding occurs e g pregnancy tests u albumin tests and crp. Cellulose acetate is used as a film base in photography as a component in some adhesives and as a frame material for eyeglasses. With high physical strength the membrane filters can be used up to 180ºc are suitable for hot gases and can be sterilized by all methods without sacrificing the integrity of the membrane. The cellulose acetate membranes have improved solvent resistance particularly to low molecular weight alcohols and increased heat resistance.

In photographic film cellulose acetate replaced nitrate film in the 1950s being far less flammable and cheaper to produce. Cellulose acetate became widely used in the automotive industry because of its mechanical strength toughness wear resistance transparency and ease of moldability. Acetate sheets often work with dry erase markers meaning they are easily customizable and reusable. Manufacturers form it into sheets that are 0 1 mm to 0 5 mm thick.

Acetate paper is available at baking craft and office supply stores. This nonflammable mildew proof material is easy to dye and is available in many colors. Cellulose diacetate film was first created by the german chemists arthur eichengrün and theodore becker who patented it under the name cellit from a process they devised in 1901 for the direct acetylation of cellulose at a. This 25 mm mf millipore membrane is composed of mixed cellulose membrane has a 0 8 um pore size.

Cellulose acetate is used as a film base in photography as a component in some coatings and as a frame material for eyeglasses. A nitrocellulose slide nitrocellulose membrane or nitrocellulose paper is a sticky membrane used for immobilizing nucleic acids in southern blots and northern blots. Cellulose acetate is made by esterifying bleached cotton or wood pulp with acetic acid. With biologically inert mixtures of cellulose acetate cellulose nitrate mf millipore membranes are widely used in analytical research applications.

Cigarette filters are usually made from cellulose acetate fibre but sometimes also from paper or activated charcoal either as a cavity filter or embedded into the cellulose acetate. It was first prepared in 1865. Acetate paper is a transparent material that is made by reacting cellulose with acetic acid in the presence of sulfuric acid. It was introduced in the early 20th century by film manufacturers and intended as a safe film base replacement for unstable and highly flammable nitrate film.

Its high resistance to impact made it a desirable material for protective goggles tool handles oil gauges and the like. It is also used for immobilization of proteins in western blots and atomic force microscopy for its nonspecific affinity for amino acids. It is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards.
