PES代表什么材料
聚醚砜(PES)是一种耐高温的热塑性工程塑料。具有韧性、硬度好及显著的长期承载特点。在200度性能仍稳定,耐蠕变,在有负荷下可在180度下使用。具有熄性(UL94V—0)。稍能吸水,平衡后形变在0.15%左右。作特种粘合剂及涂料,可耐温200度以上。化学稳定性好,耐酸、碱、直链烃,汽油类。部分溶于芳烃。PES在-40~200度之间电性能无明显改变,尺寸稳定性好。
拓展资料:聚醚砜制轴承保护罩用于轿车、载重货车的齿轮箱。汽车风扇,齿形卷棒、军工精密零件、继电器、印刷电路板、接线扳、热水表、热阀门、饮水和食品接触的专用材料。灯具材料,如反光镜、灯,实验室用的离心器罩、钻头的手柄。雷达天线罩、飞机舱外部配件等。
pes和ppsu材质有什么区别
PES材质,化学名称是聚醚砜,为无色外表,透明度高,耐高温、耐磨损,要比PP材质的奶瓶优质些。
PPSU材质,化学名称是聚苯砜,外表颜色是淡淡的金黄色,这一材质要比其他两种材质的更优质,产品耐高温达180度,能反复的消毒,不会产生有害成分。PES奶瓶稳定性高,不轻易变形、耐腐蚀。
长期使用温度的话,PES大概在170度左右。PPSU是180度,耐消毒能力PES 100-200次,PPSU2000次以上,在耐有机物方面 PES性能远不如PPSU,在耐酸碱方面两者相差不大,水解稳定性,PPSUPES,生物适应性PPSU可以,PES完全不可以。

塑料奶瓶的材质有PC、PP(聚丙烯)、和PES(聚醚砜),其中,PP和PES材质的塑料奶瓶大多是比较安全的。消费者在购买奶瓶时一定要看清材质,还可以通过塑料瓶
pes是什么材质
PES也称为聚醚砜,是一种透明琥珀色的无定型树脂,具有优异的耐热性,优良的尺寸安定性,以及良好的耐化学品性。PES对急剧温度变化显现优良的可靠性,加工成型性优良使PES有广泛的应用。
PES奶瓶是塑料奶瓶的一种,目前是比较受欢迎的奶瓶材质之一。PES奶瓶优点:轻巧耐摔,易清洗,安全不含双酚A。耐热性高,可耐热180℃。PES奶瓶缺点:残留的奶垢不容易清洗。
PES奶瓶:特别为瓶身较轻,安全性高,使用方便。没有环境荷尔蒙的疑虑,不过瓶身透光性略低,价格约比PC奶瓶多1/3左右。塑料中,PES、PC,质轻强度高,不易破碎,高度透明,性能都不错,不考虑价格因素的话,是首选。尤其新新材料PES,比PC更易洗、耐用,几近于玻璃。
