cellulose triacetate
polymerCellulose triacetate is a thermoplastic polymer derived from cellulose through complete acetylation of hydroxyl groups, creating a material with good transparency, dimensional stability, and chemical resistance. It is primarily used in optical applications such as camera film, LCD polarizers, and protective sheets, as well as in cigarette filters and specialty membranes where its combination of clarity and mechanical stability is valued. Compared to cellulose acetate (which is only partially acetylated), cellulose triacetate offers superior solvent resistance and higher hydrolytic stability, making it the preferred choice when long-term durability in moisture-rich or chemically aggressive environments is critical.

Safety & Biocompatibility
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
