CAFBLO® Flake

01Features

In recent years, cellulose derived from wood and cotton has garnered attention as an environmentally friendly resin. Acetate cellulose is a highly safe substance for biological systems.
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.
It is flame-resistant, with a high melting point that causes it to melt and carbonize at 230-300°C.
It exhibits good chemical resistance, unaffected by organic and inorganic weak acids, animal and vegetable oils, and gasoline.
With low electrical conductivity and high internal and external resistance, it serves as an excellent insulating material.

Representative testing items and testing methods for cellulose acetate

Property Test Method
Moisture Dry sample in an oven for 2hr at 105℃, and weigh accurately
Conbines Acetic Acid After extracting the acetic acid content in the sample, perform neutralization titration.
6% Viscosity Measure the time of flow at 25℃ with an Ostwald viscometer.
Boiling Water Stability After extracting the acetic acid content in the sample with boiling water, neutralization titration is performed.
Ash content The sample is put in a crucible, carbonized with an electric heater, and ashed in an electric furnace.
Yellowness Index Dissolve the sample in a solvent and measure the Yellowness Index.
