Texto del producto

Eastar™ BR203 copolyester has excellent appearance and is nearly water clear. With superior chemical resistance, it maintains its physical properties and appearance when exposed to aromatic oils. BR203 is specifically formulated to provide the optimal combination of chemical resistance, bristle retention, strength, stiffness, processability, clarity, colorability, and feel for toothbrushes. Under existing United States Food and Drug Administration (FDA) regulations, Eastar™ BR203 copolyester may lawfully be used to make food contact articles which comply with the specifications and conditions of use in 21 CFR 177.1240.
