The wet strength of nylon is 80-90% of its dry strength and the elongation at break increases by 5-30% on wetting. Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine, and adipic acid, which give nylon 6 6 its name. Sean Pelfrey. The tenacity varies from 8.8-4.3 gpd while corresponding elongation at break varies from 18-45%. They can be used interchangeably for various applications, but there are some property differences to note: Nylon 6: Nylon 6 is usually produced in two forms: for textile use and high-strength types for industrial uses. Molecular weight of repeat unit: 226.32g/mol . Si un seul numéro est mentionné, cela signifie que le monomère est un aminoacide Alpha (ou son lactame) et que les chaînons amides dans le polymère sont tous "tête à queue". Therefore it is cheaper to make Nylon 6 than Nylon6,6. Basic: Basic does not cause harm to the nylon 6. A 153P0118. Nylon 66.
