Name: Eastman CA 398-10 Cellulose Acetate
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Eastman CA 398-10 Cellulose Acetate

High acetate substitution (DS ~2.4–2.5) for excellent solubility in common organic solvents including acetone, ethyl acetate, and methyl ethyl ketone.
Consistent rheology and film-forming capability, enabling reliable performance in solvent-based coating and casting processes.
Good thermal stability and low moisture absorption, supporting dimensional stability in precision optical and industrial film applications.
Optically clear, color-stable resin with low haze—ideal for high-clarity transparent films and laminates.
Regulatory-compliant formulation suitable for indirect food contact applications per FDA 21 CFR §175.300 and EU Directive 2002/72/EC.

Typical Applications Of Eastman CA 398-10 Cellulose Acetate

Transparent protective overcoats for flexible printed electronics and membrane switches.
Base resin for high-gloss decorative laminates used in automotive interior trim and appliance panels.
Carrier film for pressure-sensitive adhesive transfer tapes requiring clean unwind and dimensional fidelity.
Optical-grade substrate for anti-reflective and hard-coat laminated films in display protection.
Binders and film formers in specialty inks for gravure and flexographic printing on non-porous substrates.
