EPiC database - Nylon 66

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.<br><br>Nylon 66 (nylon 6-6, nylon 6/6, or nylon 6,6) is a polyamide made from two monomers with six carbon atoms each. It has high mechanical strength, rigidity, good stability under heat and chemical resistance.<br><br>Nylon 66 is synthesised by polycondensating hexamethylenediamine and adipic acid. The same amount of each monomere are mixed with water and crystallised to produce a nylon salt. The salt is polymerised and nylon 66 is formed. It can be extruded, granulated or spun into fibres.<br><br>Nylon 66 is mostly used as a sheet in construction, but also in rods, tubes, screws, washers, ropes and spacers.

尼龙66（又称尼龙6-6、尼龙6/6或尼龙6,6）是一种由两种各含6个碳原子的单体合成的聚酰胺材料，其具备优异的力学强度、刚性，良好的热稳定性与耐化学腐蚀性能。

尼龙66通过己二胺与己二酸的缩聚反应合成：将等物质的量的两种单体与水混合并结晶，制得尼龙盐；随后对该盐进行聚合反应，即可得到尼龙66。该材料可经挤出成型、造粒或纺丝制成相应形态。

尼龙66在建筑领域中主要以板材形式应用，同时也可用于制造棒材、管材、螺钉、垫圈、绳索及隔垫等制品。
