品牌：Sabic 品名：Noryl 品类：PPO 牌号：640 640物性表.pdf 色号：640-111 中文简介：640，是一种基于聚苯醚（PPE）的中高分子量聚合物。PPO旨在用作各种热塑性塑料和热塑性弹性体如苯乙烯嵌段共聚物的添加剂或结构单元。PPO树脂可用于改善热变形和抗蠕变性等性能。它是水解稳定的和非吸湿的（通常小于0.2％的水吸收）。该聚合物可溶于普通的有机溶剂，如甲苯，氯仿和THF。化学名称：聚（2,6-二甲基-1,4-亚苯基醚）（PPE）分子式：（C8H8O）n法规状态：符合FDA法规21CFR
177..2460。也符合欧盟指令2002/72 / EC。 英文简介：PPO 640 resin is a medium-high molecular weight polymer based on Polyphenylene Ether (PPE). PPO is intended for use as an additive or a building block in a variety of thermoplastics and thermoplastic elastomers
like Styrenic Block Copolymers. PPO resin can be used to improve properties like Heat Distortion and Creep Resistance. It is hydrolytically stable and non-hydroscopic (typically less than 0.2% water uptake). The polymer is soluble in common organic solvents
like toluene, chloroform, and THF. Chemical name: Poly (2,6-dimethyl-, 1,4-phenylene ether) (PPE) Formula: (C8H8O)n Regulatory Status: Complies with the FDA regulation 21CFR 177..2460. Also complies with EU Directive 2002/72/EC.
