What is cellulose acetate?
It is made by treating cellulose with acetic acid and acetic anhydride using catalysts (sulfuric acid). The cellulose triacetate has 62,5% of acetic acid combined, furthermore is soluble in the reaction of acids; it is put into the water, washed and dried. The compositions for molding of cellulose acetate are prepared with acetate flakes, plasticizers (10-70 parts), pigments and dyes, by mixing these ingredients in cylinder mixers, extruders or in closed mixer (Banbury) at temperatures between 175 ° C and 270 ° C.
The cellulose acetate has good properties of toughness and impact resistance; it is stable at room temperature and has good resistance to discoloration when it is exposed at sunlight. This material can be produced in a wide selection of colors, in transparent or translucent form. The field of applications is very broad including toys, sundries, household; in form of sheets, it is widely used in packaging, electrical insulation and belts. It is also used in large quantities for the production of photographic films not flammable.
