PES是什么材料
PES是乙烯-醋酸乙烯共聚物,一般醋酸乙烯(VA)含量在5%~40%。与聚乙烯相比,EVA由于在分子链中引入了醋酸乙烯单体,从而降低了高结晶度,提高了柔韧性、抗冲击性、填料相溶性和热密封性能,被广泛应用于发泡鞋料、功能性棚膜、包装膜、热熔胶、电线电缆及玩具等领域。

聚醚砜树脂(PES),PES是高透明,高水解稳定材料.PES耐腐蚀性:制品可经受重复的蒸汽消毒(在145℃蒸汽下至少为12年),PES具高刚性,高韧性,自身阻燃且燃烧时发烟量低。其各种优良特性使它适用于严苛环境及高性能标准的应用。
pes膜和尼龙膜的区别
pes膜和尼龙膜的区别如下:
1、特点不同
尼龙膜耐高温性良好,可耐121饱和蒸汽热压消毒30分钟,高工作温度60摄氏度(℃),化学稳定,能耐受稀酸、醇类(alcohols)、酯类、油类、碳(C)氢(Hydrogen)化合物、卤代烃及有机氧(Oxygen)化(oxidation)物等多种有机和无机化合物。
pes膜是聚醚砜材料品质的微孔滤膜属于亲水性滤膜,具有高流率、低溶出物、良好的强度的特点,不吸附蛋白和提取物,对样品无污染。
2、用途不同
尼龙膜是电子、微电子、半导体(semiconductor)工业水过滤、组织培养基过滤、药物过滤、饮料过滤、高纯化学制品过滤、水溶液和有机流动相的过滤。
隔膜真空泵设计先进,工作效率高,使用寿命长,是集高新技术于一体的换代产品。主要应用于医疗医药产品分析、精细化工、生化制药、食品检验、公安刑侦技术等。
pes膜是低蛋白质吸附及高药物相容性,专为生化、检验、制药及除菌(fungus)过滤装置而设计。
高分子膜
以有机高分子聚合物为材料制成的薄膜。随着石油工业和科技的发展,高分子膜的应用领域不断扩大,由最初的包装膜发展到了智能高分子膜、高分子功能膜等。
其中用量更大的是选择性分离膜,如离子交换膜、微孔过滤膜、超过滤膜、液膜、液晶膜等。已应用的领域有核燃料及金属提炼、气体分离、海水淡化、超纯水制备、污废处理、人工脏器的制造、医药、食品、农业、化工等各方面。
pes材质是什么
聚醚砜树脂(PES)。英文翻译为: Poly(ether sulfones),
PES是高透明,高水解稳定材料.PES耐腐蚀性:制品可经受重复的蒸汽消毒(在145℃蒸汽下至少为12年),PES具高刚性,高韧性,自身阻燃且燃烧时发烟量低.我司除注塑级PES外,还提供压铸级,涂料级和超滤膜用PESPES(聚醚碸,Polyether Sulfone),为高性能热可塑性非结晶型工程塑胶,自然色为透明琥珀色,其各种优良特性使它适用于严苛环境及高性能标准的应用,GAFONE? PES可使用各种传统的热塑性加工设备,如:射出、压出、吹气成形等加工方式。
