Name: Eastman CA 320S NF/EP Cellulose Acetate
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Eastman CA 320S NF/EP Cellulose Acetate

Complies with United States Pharmacopeia (USP) NF and European Pharmacopoeia (EP) monographs for cellulose acetate, ensuring regulatory suitability for pharmaceutical and medical applications.
Offers balanced solubility in common organic solvents such as acetone, ethyl acetate, and methyl ethyl ketone—enabling versatile processing via casting, extrusion, or coating.
Delivers excellent film-forming capability with high clarity, low haze, and good mechanical toughness for demanding functional films and membranes.
Features consistent acetyl content (~39.8–40.2 wt%) and viscosity performance, supporting reproducible formulation behavior and batch-to-batch reliability.
Manufactured under strict quality control in ISO-certified facilities, with full traceability and documentation compliant with ICH Q7 and FDA cGMP expectations.

Typical Applications Of Eastman CA 320S NF/EP Cellulose Acetate

Pharmaceutical controlled-release coatings for tablets and pellets, including enteric and sustained-release film systems.
Medical device components requiring biocompatible, extractables-controlled polymeric films—e.g., wound dressings and transdermal patch backings.
High-clarity filtration membranes for sterile filtration and analytical sample preparation in regulated laboratories.
Food contact-approved packaging films where regulatory compliance (FDA 21 CFR §175.300) and barrier performance are critical.
Specialty ink binders and overprint varnishes for pharmaceutical and nutraceutical blister packaging.
