Eastar BR203|TPC|Eastman物性表报告及物性特性介绍,Eastar BR203|TPC|Eastman注塑参数详情-塑料物性表查询网

Product TextsApplication/Uses It has excellent appearance and is nearly water-clear. Its 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 单位(Unit)ed 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.
