Cellulose diacetate NEW

Product introduction

Cellulose diacetate, sometimes called diacetate, is a synthetic polymer made by treating cellulose with acetic acid. It consists of two acetate radicals on each unit of D-anhydroglucopyranose of the cellulose molecule. It was first developed in the United States.

It is distinguished from cellulose acetate and cellulose triacetate.
It is fragile since it is based on cellulose. When cellulose diacetate deteriorates, it shrinks and releases acetic acid, causing a "vinegar syndrome".
Cellulose diacetate was used to make fabrics, membranes, and filaments. From 1922 to 1957 it was used to make film stock, mainly in smaller formats such as 8 mm, 16 mm, 35 mm, and 70 mm.
A cellulose diacetate film is also called a safety film.
The cellulose diacetate is biodegradable and hydrophilic.

Cellulose acetate refers to a thermoplastic resin obtained by esterification with acetic acid as solvent and acetic anhydride as acetylation agent under the action of catalyst, and is the earliest commercial production and continuous development of cellulose organic acid ester among cellulose derivatives. As a porous membrane material, cellulose acetate has the characteristics of high selectivity, large water permeability and simple processing.
