Material Notes:
Eastar BR203 Copolyester contains a mold release additive. It has excellent appearance and is nearly water-clear. Its most outstanding features are its chemical resistance and processing capabilities. Exposure to aromatic oils often causes crazing or actual fracture of many polymer resins, but BR203 maintains its physical properties when exposed to these oils, and its appearance is virtually unchanged. BR203 is specifically formulated to provide the optimal combination of chemical resistance, bristle retention, strength, stiffness, toughness, 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.Applications/UsesToothbrushes
