Environmental Notes

Cellulose acetate is a natural, renewable cellulose-based polymer, which can therefore qualify as biopolymers. The processing, however, involves chemicals that create a problem of disposal. Most cellulose-based polymers burn easily, requiring protection from naked flame. Some are biodegradable.

Effect of Composition

The viscosity increases with increasing acetate contents: 44-48% - low viscosity, 52-56% - medium viscosity and 56-61% - high viscosity. To enable thermoplastic processing, 15-20 wt% plasticizers are added to the resin. Modulus and tensile strength decrease linearly with increased plasticizer content. Heat distortion point decreases and melt flow rate and creep tendencies under load increase with increased plasticizer content.

Typical uses

Cosmetic containers, tool handles, steering wheel covers, spectacle frames, pens, packaging, toys and models, brush handles. Low viscosity: textile production and printing inks, medium viscosity: coatings and adhesives (molding grades) and high viscosity: safety- and electro-insulation films. Cigarette filters are by far the largest use of CA.

Other notes

CA cannot be mixed with either CAP or CAB.
