1·When selecting from the array of conventional high impact polyamides, power tool manufacturers often have to compromise in respect of either high impact resistance or stiffness.
在各种传统高抗冲聚酰胺材料中进行选择时，电动工具制造商经常必须在高抗冲性和刚度之间作出取舍。
2·The high mechanical properties of impact modified polyamides bring benefits to applications as diverse as power tools or sports articles.
冲击改性聚酰胺的高机械性能使越来越多的电动工具或运动用品受益。
3·Polymer membrane Recently, polymer membranes made from polyamides and polysulfones have taken the place of cellulose acetate, at least for ultrafiltration.
聚合物膜近年来，由聚酰胺和聚砜制成的聚合膜至少在超滤时已取代了纤维素醋酸酯。
4·The two most important synthetic polyamides are the urea-formaldehyde resins and the various forms of nylon.
两种最重要的合成聚酰胺是脲甲醛树脂和各种形式的尼龙。
5·Those polyamides used commercially are sufficiently stable to be spun from a melt.
这些商业用的聚酰胺在熔融纺丝过程中十分稳定。
