Nylon drag chain Compared with plastic drag chain, it has higher mechanical strength, better abrasion resistance and flexibility. Therefore, when considering the choice of nylon drag chain and plastic drag chain, nylon drag chain is a better choice. ‌

The main advantage of nylon drag chain is its material. It contains nylon PA6 or nylon PA66 material, which has higher mechanical strength and better wear resistance. ‌

The physical properties of nylon 6 and nylon 66 are similar, but the difference is that the melting point of nylon 6 is 220 ° C, while that of nylon 66 is 260 ° C. ‌

Both have good antifouling, dustproof and stability, and good fatigue resistance. In production Engineering plastic drag chain Glass fiber is added to both of them, and the difference after molding is shown as follows:

Nylon 6 has better toughness, while nylon 66 has better strength and abrasion resistance. The drag chain mainly works in a moving environment, and will have a lot of friction with the contact surface, so wear resistance is the main factor determining its service life. ‌

The main material of plastic drag chain is engineering plastic, which is characterized by low cost and good oxidation resistance. ‌

Although plastic drag chain has certain advantages in cost and oxidation resistance, nylon drag chain performs better in mechanical strength, abrasion resistance and flexibility, and is more suitable for application scenarios requiring higher performance protection. ‌

To sum up, because of its higher mechanical strength, better abrasion resistance and flexibility, nylon drag chain is more suitable for applications requiring higher performance protection. Therefore, nylon drag chain is a better choice.
