Cellulose Acetate Paper Uses

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.

Cellulose acetate paper uses.

It was first prepared in 1865. Its high resistance to impact made it a desirable material for protective goggles tool handles oil gauges and the like. Cellulose acetate is the acetate ester of cellulose. It is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards.

Cellulose acetate is made by esterifying bleached cotton or wood pulp with acetic acid. Acetate paper is available at baking craft and office supply stores. Acetate paper is a transparent material that is made by reacting cellulose with acetic acid in the presence of sulfuric acid. 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 and in the manufacture of cigarette filters found in screwdriver handles ink pen reservoirs and x ray films. With biologically inert mixtures of cellulose acetate cellulose nitrate mf millipore membranes are widely used in analytical research applications. 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. 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.

This nonflammable mildew proof material is easy to dye and is available in many colors. This 25 mm mf millipore membrane is composed of mixed cellulose membrane has a 0 8 um pore size. Cellulose acetate film or safety film is used in photography as a base material for photographic emulsions. 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.

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 became widely used in the automotive industry because of its mechanical strength toughness wear resistance transparency and ease of moldability. In photographic film cellulose acetate replaced nitrate film in the 1950s being far less flammable and cheaper to produce. Cellulose acetate is used as a film base in photography as a component in some coatings and as a frame material for eyeglasses.

The cellulose acetate membranes have improved solvent resistance particularly to low molecular weight alcohols and increased heat resistance. Cellulose acetate is used as a film base in photography as a component in some adhesives 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.
