eastar™ an004, natural
共聚多酯
产品说明:
eastar™ an004 copolyester contains a mold release. 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 an004 maintains its physical properties when exposed to these oils, and its appearance is virtually unchanged. easy to process, it flows readily and fills intricate molds. its processability coupled with its outstanding chemical resistance makes it well suited for thick-wall applications.
