Nylon 66 (Nylon 66) and nylon 6 (Nylon 6) melting point:
Nylon 66: Nylon 66 generally has a higher melting point, giving it higher thermal stability. This allows nylon 66 to maintain better performance in high-temperature environments.
Nylon 6: Nylon 6 has a relatively low melting point but still has good heat resistance. Under some low temperature and high humidity conditions, nylon 6 may perform better than nylon 66.
