nylon Knowledge
polyamide (PA) nylon （Nylon）, 英文名称Polyamide（简称PA）, is separation 子主链 upper has heavy amine

基团—[NHCO]— thermoplastic property resin 总称. aliphatic PA, 脂肪— aromatic PA and aromatic PA. its in, aliphatic PA product types more, PA66 output/production volume large, application 广泛, its 命名由 combined formed mono specific carbon 原子数而定. nylon in main/primary product types is nylon 6 and nylon 66, for 主导 位, its is nylon 11, nylon 12, nylon 6 10, nylon 612, another also has nylon 1010, nylon 46, nylon 7, nylon 9, nylon 13, new product types has nylon 6 I, nylon 9T and nylon MXD6（ retardant property resin ） and other, nylon modified product types amount more, reinforcement nylon, mono 体浇铸 nylon （MC nylon ）, reaction injection molding （RIM） nylon, aromatic nylon, transparent nylon, high impact resistance （ super tough ） nylon, electroplating nylon, conductive nylon, flame retardant nylon, nylon and other polymer blending material and alloy and other, meet/satisfy different requirements, used as metal, and other 传统材 material use product, as is various 结 构材 material.

nylon is most important engineering plastics, output/production volume in large general purpose engineering plastics in 居首位

property can : nylon is tough property semi transparent or white crystallization property resin, as is engineering plastics nylon molecular weight generally is 1.5-3万 nylon tool has very high machine strong/high degree, soft high, heat resistant, abrasion scratch low, wear resistant loss, lubricated property, property and property, oil resistant, resistant low acid, resistant alkali and generally solvent agent, electrical insulation property good, has self-extinguishing property, 无毒, 无臭, weather resistance good, 染****差. disadvantages is water property large, effect/influence dimensional stability and electrical property can, fiber reinforcement can reduce resin water absorption, make its can in high temperature, high wet lower as. nylon and glass fiber hydrophilic combined property separation good.

nylon in nylon 66 hardness, rigid property most high, tough property most 差. various nylon tough property large small is: PA66＜PA66/6＜PA6＜PA610＜PA11＜PA12.

nylon property is UL 94v-2 grade , oxygen index (LOI) is 24-28, nylon separation understanding temperature degree ＞299℃, in 449~499℃时会发生自燃.

nylon melt flow property good , products thick can small to 1mm.
