Silk-screen printing: it is the most used process for printing of effects where the definition of the color point or the use of metallic inks is fundamental.Printing processes give the possibility to print any drawing on Cellulose Acetate sheets they are: This process also involves the use of components obtained through the printing process. For example, it is possible to take a monocolor extruded sheet and laminate a thin block layer on it to obtain a frame that will have a variegated top or vice versa. Lamination process: lamination allows multiplying the effects by combining different components, obtained from the previous three processes, in a new sheet by lamination.After melting product is ready to be used. In this case, unlike the block process, there are no solvents. Compression process: it is a process that uses semi-finished products coming from the first two processes which, cut into predetermined shapes, are brought back to fusion in a mold that allows to obtain a sheet.As a matter of fact our designers, starting from the design of the sheets that we want to obtain, develop a dye that allows the union of several distinct flows of molten material that combine precisely within the sheet creating the design. In this case Mazzucchelli's experience is poured into the design and construction of the dye which is a true work of engineering. Once outside the dye, the sheet is cooled and cut into the appropriate size.

This process involves the use of a co-extrusion line where granules of varied colors are melted and passed through a dye.

Extrusion process: this is an industrial process which allows to obtain sheets from colored granules.

This process is unique in the world and thanks to our decades of experience it allows us to create infinite aesthetic effects to satisfy the needs of designers. These sheets, after appropriate removal of the solvent by special ovens, are 'straightened' in flat presses and inspected one by one. After the last pressing, the final sheets are cut to the desired thickness. This process can be repeated several times obtaining more or less sophisticated products. To obtain our effects, we start with at least two monocolor blocks that are reduced to sub-formats and then reassembled until a new block is obtained. The product obtained from the fusion is a monocolor block. At this point, again through the calendering process, the mixture is reduced in the form of raw sheets which are superimposed in presses and, by means of heat and pressure, melted. The raw materials used in this process are Cellulose Acetate powder, plasticizers and solvents these raw materials are mixed together until a malleable dough is obtained which, after heavy filtration to remove any impurities, is colored by a calendering process that homogenizes the colors in the mass.

Block process: process of sophisticated craftsmanship which allows to obtain three-dimensional designs ranging from natural effects, through the reproduction of fabrics to reach geometric effects of great impact and complexity.

Phthalate plasticizer has been replaced by a proprietary plasticizing solution of vegetable origin.

HX formulation, more rigid than the first.

Standard formulation, plasticized with DEP.Other additives such as light and heat stabilizers (dyes and pigments) can be added in small quantities if necessary.įormulations offered by Mazzucchelli for the sheets are: To obtain Cellulose Acetate we start with the selection of renewable sources such as certain varieties of trees and cotton linters.įrom these sources the purest part of the cellulose is extracted which is subsequently treated with Acetic Anhydride and transformed into Cellulose Acetate powder.ĭuring Mazzucchelli’s processes, this powder is intimately mixed with substances aimed at giving the desired workability, flexibility and toughness: the so called plasticizers. Cellulose acetate is a modified natural polymer.
