CONT

Cellulose Triacetate Films (CTA) are noted for the wide range and versatility of their chemical and physical properties which make them a preferred choice of material in a wide range of industrial applications. CTA must be processed into film in a solution, due to its very high softening temperature that cannot be significantly reduced by added plasticizers.
