PA12 materials PA12 is nylon 12, also known as poly dodecalactam, poly laurolactam, is a long carbon chain nylon. Nylon 12 in the existence of non-polar methylene groups, and a large number, which makes the nylon 12 molecular chain of the greater flexibility; nylon 12 amide groups in the polarity, and cohesion energy is very large, and its molecules can be formed between the hydrogen bonding, so that the molecular arrangement of the more regular. Therefore, the crystallinity of nylon 12 is high, and the strength is also high. Nylon 12 (PA12) low water absorption, good low temperature resistance, good airtightness, alkali resistance, grease resistance is excellent, resistance to alcohols and inorganic dilute acids and aromatics performance is medium, mechanical properties and electrical properties are also good, and is a self-extinguishing material.
