PP cigarette filter tip substitute Cellulose acetate

Cellulose acetate (CA) is a semi-synthetic polymer material produced through the acetylation reaction of natural cellulose, combining biodegradability with chemical stability. Its unique porous structure, non-toxic properties, and tunable physical characteristics make it an essential material for cigarette filters and a high-value excipient in the pharmaceutical industry. It can also be used to produce enteric coatings for pharmaceuticals, cellulose acetate filter membranes, and other applications. Additionally, it is utilized in the production of cellulose acetate plastics and cellulose acetate filter membranes.
