Acetate cellulose is a highly safe substance for biological systems.<br> Textiles, molded products, coating films, and paints made from acetate cellulose have strong resistance to sunlight (especially ultraviolet rays), allowing them to be used for extended periods without easy degradation.<br> It is flame-resistant, with a high melting point that causes it to melt and carbonize at 230-300°C.<br> It exhibits good chemical resistance, unaffected by organic and inorganic weak acids, animal and vegetable oils, and gasoline.<br> With low electrical conductivity and high internal and external resistance, it serves as an excellent insulating material.</p> <div class="wrap-img"> <figure class="max-600 ml-auto mr-auto"><img src="img/img_flake_01.png" alt="" width="600" height="371" loading="lazy"></figure> </div> </section> </div> <div class="wrap-con" id="anc-2"> <section class="con-inner"> <h2 class="heading-1"><span class="font-min">02</span>Technical information</h2> <div class="sp-s-scroll mb-3"> <table class="flake01"> <colgroup> <col class="width-25"> <col row="5" class="width-15"> </colgroup> <thead> <tr> <th scope="col">Production item</th> <th scope="col">L-50</th> <th scope="col">DACP</th> <th scope="col">DACZ</th> <th scope="col">VFS</th> <th scope="col">VFRZ</th> </tr> </thead> <tbody> <tr> <th scope="row">Form</th> <td colspan="3">Flake</td> <td colspan="2">Powder</td> </tr> <tr> <th scope="row">Moisture (%)</th> <td colspan="5"><6.0</td> </tr> <tr> <th scope="row">Conbines Acetic <br class="sp-s-only">Acid (%)</th> <td>54.0～56.0</td> <td colspan="4">54.5～55.9</td> </tr> <tr> <th scope="row">6% Viscosity (mPa.s)</th> <td>102～120</td> <td colspan="4">65～135</td> </tr> <tr> <th scope="row">Boiling Water <br class="sp-s-only">Stability (%)</th> <td colspan="5"><0.10</td> </tr> <tr> <th scope="row">Ash content (%)</th> <td><0.10</td> <td><0.10</td> <td><0.10</td> <td>-</td> <td>-</td> </tr> <tr> <th scope="row">Yellowness Index</th> <td>-</td> <td><5.5</td> <td><4.0</td> <td><5.5</td> <td><4.0</td> </tr> <tr> <th scope="row">package</th> <td>Paper bag (25kg)</td> <td>Paper bag (30kg)</td> <td>Paper bag (30kg)</td> <td>Paper bag (25kg)</td> <td>Paper bag (25kg)</td> </tr> </tbody> </table> </div> <section class="flake02"> <h3 class="heading-3">Representative testing items and testing methods for cellulose acetate</h3> <table> <colgroup> <col class="width-30"> <col class="width-70"> </colgroup> <thead> <tr> <th scope="col">Property</th> <th scope="col">Test Method</th> </tr> </thead> <tbody> <tr> <th scope="row">Moisture</th> <td>Dry sample in an oven for 2hr at 105℃, and weigh accurately</td> </tr> <tr> <th scope="row">Conbines Acetic Acid</th> <td>After extracting the acetic acid content in the sample, perform neutralization titration.</td> </tr> <tr> <th scope="row">6% Viscosity</th> <td>Measure the time of flow at 25℃ with an Ostwald viscometer.</td> </tr> <tr> <th scope="row">Boiling Water Stability</th> <td>After extracting the acetic acid content in the sample with boiling water, neutralization titration is performed.</td> </tr> <tr> <th scope="row">Ash content</th> <td>The sample is put in a crucible, carbonized with an electric heater, and ashed in an electric furnace.</td> </tr> <tr> <th scope="row">Yellowness Index</th> <td>Dissolve the sample in a solvent and measure the Yellowness Index.</td> </tr> </tbody> </table> </section> </section> </div> <div class="wrap-btn back"><a href="/cell_ac/en/" class="link-btn blue icon-link">Home</a></div> <div class="wrap-bread"> <ul> <li><a href="/cell_ac/en/">Home</a></li> <li>CAFBLO<sup>®</sup> Flake</li> </ul> </div> </section>  </main> <footer>   </footer> <script src="/cell_ac/en/common/js/jquery.js"></script> <script src="/cell_ac/en/common/js/common.js"></script> <script src="/cell_ac/en/common/js/tpl.js"></script> </body> </html>
