Pa6 is also called nylon 6, and its monomer is caprolactam, which is a polymer compound polymerized from caprolactam. Nylon 6 has the characteristics of thermoplasticity, light weight, good toughness, good chemical resistance and durability, and is generally used in automobile parts, mechanical parts, electronic and electrical products, engineering accessories and other products.
The chemical and physical properties of nylon 6 are similar to those of nylon 66, but it has a low melting point and a wide processing temperature range. Its impact resistance and solubility resistance are better than nylon 66 plastic, but its hygroscopicity is also stronger. Because many quality characteristics of plastic parts are affected by hygroscopicity, this point should be fully considered when designing products with nylon 6.
