Tank chain can be divided into steel tank chain and plastic tank chain according to material. Generally speaking, plastic tank chain can be made of two materials, polypropylene and nylon. Although there are two kinds of materials, customers usually turn into plastic cable drag chains, which causes some tank chain manufacturers to fake. Bottom Nylon drag chain manufacturer Let's introduce the difference between plastic tank chain and nylon tank chain.

Because the price of polypropylene raw material is only half of that of nylon, there are some relatively unscrupulous manufacturers. Polypropylene cable drag chains are commonly used to counterfeit nylon tank chains with high cost performance. Because their appearance design is very similar, it is difficult for ordinary customers to distinguish them. The following section will give a detailed introduction from the performance level of the two materials to distinguish between the two tank chains. What is good is good and what is bad is bad.

Polypropylene has low relative density, non-toxic, odorless, low melting point (160-175 ℃), hard texture, and is easy to be brittle and aging resistant at ultra-low temperatures, and is not resistant to wear and aging. Therefore, the made plastic tank chain is hard and brittle, easy to break, not heat-resistant, not abrasion resistant, easy to aging, and greatly disturbed by seasonal factors.

Nylon has a high melting point (the melting point of nylon PA6 is 220C, while that of nylon PA66 is 260C). It has wear resistance, dust resistance, clean-up and pollution resistance. It has excellent resilience, fatigue mitigation and heat resistance. It is not cold resistant and raw materials are very easy to absorb moisture. Therefore, nylon tank chain has the advantages of excellent wear resistance, oil stain resistance, dust resistance, fatigue alleviation, aging resistance, and stable high temperature. The characteristics of its material have been improved by adding glass fiber and fire retardant.

Therefore, although the price of polypropylene tank chain is only half of that of nylon tank chain in the selection process, as a tank chain for repeated movement, wear resistance and fatigue alleviation are the most important indicators. Therefore Nylon drag chain The manufacturer thinks nylon tank chain is a suitable choice!
