Eastar™ BR001共聚酯具有优异的外观和近乎水透明。其最突出的特点是耐化学性和加工能力。暴露在芳香油中通常会导致许多聚合物树脂开裂或实际断裂,但当暴露在这些油中时,BR001保持其物理性能,其外观几乎不变。BR001是专门为牙刷提供耐化学性、刷毛保持力、强度、硬度、加工性、清晰度、着色性和手感的最佳组合而设计的。根据现行的美国食品药品监督管理局(FDA)法规,Eastar™ BR001共聚酯可合法用于制造符合21 CFR 177.1240(a)规范和使用条件的食品接触物品。BR001样品的迁移试验符合21 CFR 177.1240(3)(1)、(2)和(3)的要求。本产品已通过绿色卫士室内空气质量认证。Greenguard室内空气质量认证标志是通过Greenguard环境研究所(GEI)许可使用的注册认证标志。GEI是一个行业独立的非盈利组织,负责监督Greenguard认证计划。Greenguard认证计划是一个行业独立的第三方测试计划,用于室内环境的低排放产品和材料。欲了解更多关于GEI的信息,并获得Eastman共聚酯的可打印证书,请访问www.greenguard.org。在制造商类别下选择Eastman Chemical Company,然后单击搜索以显示我们的产品列表。 Eastar™ BR001 Copolyester 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 BR001 maintains its physical properties when exposed to these oils, and its appearance is virtually unchanged. BR001 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™ BR001 copolyester may lawfully be used to make food contact articles which comply with the specifications and conditions of use in 21 CFR 177.1240(a). Migration tests on BR001 samples meet the compliance requirements of 21 CFR 177.1240(3)(1), (2) and (3). This product has been GREENGUARD INDOOR AIR QUALITY CERTIFIED®. The GREENGUARD INDOOR AIR QUALITY CERTIFIED® Mark is a registered certification mark used under license through the GREENGUARD Environmental Institute (GEI). GEI is an industry-independent, non-profit organization that oversees the GREENGUARD Certification Program. The GREENGUARD Certification Program is an industry independent, third-party testing program for low-emitting products and materials for indoor environments.
