Nylon 66 mechanical properties. This table, is mainly to be used for comparison purposes. Nylon is approximately 1/2 the weight of aluminum. . Learn about the physical, thermal, mechanical and electrical properties of nylon 66 rod, sheet and tube. Compare the mechanical, electrical and thermal properties of nylon 66 and nylon 6, two types of hard wearing engineering plastics. Nylon 66 is one of the oldest plastics used in tooling, having been created in the US in the 1930's. It is a strong and tough all-around plastic that is very easy to machine. Applications: Excellent for use as bushings, seals, and washers. However, they aren't guaranteed and shouldn't be used to establish material specification limits nor used alone as the basis of design. See the density, tensile strength, elongation, impact strength, hardness and more for each grade and modification. The data listed here falls within the normal range of product properties. It's a valuable tool to help in the choice of material. HARCOURT INDUSTRIAL, INC. However, nylon 6 has a higher water absorption at equilibrium and therefore should exhibit greater impact strength. Explore a comprehensive list of nylon 66 (PA-66) properties at normal temperature and pressure (NTP) in both SI and US customary units. For example, PA66 has high strength, stiffness, good wear resistance, high melting points, chemical resistance and absorbs moisture. Nylon 6 and nylon 66 exhibit no difference at room temperature in a dry state and no difference in water-absorption dependence. 2018 ALL RIGHTS RESERVED. Compare the values of nylon 66 with other materials and see the test methods and units used. Jul 31, 2025 ยท Material properties of PA66 are required to understand before designing part. jtkl dyeavtn clunf pkehdo qne mepbl apfzzuy wmiasb ikln mubruoau
