Cellulose acetate is the acetate ester of cellulose.
Cellulose acetate paper uses.
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.
Cellulose acetate became widely used in the automotive industry because of its mechanical strength toughness wear resistance transparency and ease of moldability.
Nitrocellulose is widely used as support in diagnostic tests where antigen antibody binding occurs e g pregnancy tests u albumin tests and crp.
Manufacturers form it into sheets that are 0 1 mm to 0 5 mm thick.
This nonflammable mildew proof material is easy to dye and is available in many colors.
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.
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 is used as a film base in photography as a component in some adhesives and as a frame material for eyeglasses.
Its high resistance to impact made it a desirable material for protective goggles tool handles oil gauges and the like.
The cellulose acetate membranes have improved solvent resistance particularly to low molecular weight alcohols and increased heat resistance.
A nitrocellulose slide nitrocellulose membrane or nitrocellulose paper is a sticky membrane used for immobilizing nucleic acids in southern blots and northern blots.
With biologically inert mixtures of cellulose acetate cellulose nitrate mf millipore membranes are widely used in analytical research applications.
This 25 mm mf millipore membrane is composed of mixed cellulose membrane has a 0 8 um pore size.
Cellulose acetate is made by esterifying bleached cotton or wood pulp with acetic acid.
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.
It was first prepared in 1865.
It is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards.
Acetate paper is available at baking craft and office supply stores.
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.
Acetate sheets often work with dry erase markers meaning they are easily customizable and reusable.
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.
