尼龙中的主要品种是尼龙6（pa6）和尼龙66(pa66)，占绝对主导地位。 那么pa6与pa66的本质区别是什么？ 物理特性基本区别. 尼龙6（pa6）为 聚己内酰胺 ，而尼龙66(pa66)为 聚己二酸己二胺 ，pa66比pa6要硬l2%。

Nylon 6 or polycaprolactam is a polymer, in particular semicrystalline polyamide. Unlike most other nylons, nylon 6 is not a condensation polymer, but instead is formed by ring-opening polymerization; this makes it a special case in the comparison between condensation and …

2024年4月11日 · Polyamide 6-6 (PA6-6) or Nylon 6-6 is one of the most popular engineering thermoplastics. It is majorly used as a replacement for metal in various applications. Nylon 66 is synthesized by polycondensation of hexamethylenediamine and adipic acid.

尼龙（Nylon），中文名聚酰胺，英文名称Polyamide（简称PA），是分子主链上含有重复酰胺基团—[NHCO]—的 热塑性树脂 总称。其命名由合成单体具体的碳原子数而定。

Nylon 6 is a tough, abrasion-resistant material. It has improved surface appearance and processability compared to nylon 6/6. It also can be molded about 80 degrees F (45 degrees C) lower with less mold shrinkage because it is slightly less crystalline. Adversely, nylon 6 has a lower modulus and absorbs moisture more rapidly than nylon 6/6.

Nylon 6 is known for its strength, durability, and resistance to wear and abrasion. The following table provides a comprehensive list of nylon 6 (PA-6) properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).

2、优点：PA6是尼龙材料中，机械强度比较高的一种，但低于 PA66；拉伸强度，表面硬度，刚性都高于其它的尼龙类塑料。 抗冲性和柔性高于PA66. 鉴别： 用PA66与盐酸在110℃加热4小时，有少量白色已二酸结晶沉淀析出。 PA6没有，PA610B也有。 1、燃烧特征：同尼龙的燃烧特征。 2、优点：PA66是尼龙材料中，机械强度最高的一种，拉伸强度，表面硬度，刚性都高于其它的尼龙类塑料。 关注微信公众号 "工业材料应用" 每日更新工业塑料新闻行情. 【一起塑造】APP上 …

Nylon 6/6 is one of the most versatile engineering thermoplastics. It is popular in every major market using thermoplastic materials. Because of its excellent balance of strength, ductility and heat resistance, nylon 6/6 is an outstanding candidate for metal replacement applications.

2023年9月7日 · Polyamide Type 6, often referred to as PA Type 6, is a versatile and widely-used engineering thermoplastic material with a rich history of applications across various industries. PA Type 6 belongs to the polyamide family and is known for its unique set of properties that make it indispensable in numerous applications.

pa6是吸水率最高的pa，尺寸稳定性差，并影响电性能（击穿电压）。 PA6最高使用温度可达180℃,加抗冲 改性剂 后会降至160℃，用15%-50%玻纤增强，可提高至199℃，无机填充PA能提高其 热变形温度 。
