plastic drag chain is a type of chain. according to the structure it can be divided into bridge type plastic drag chain and fully enclosed plastic drag chain; according to the model is divided into small tow chain, general type tow chain and large tow chain; according to the noise coefficient can be divided into ordinary drag chain and silent drag chain; according to the form it can be divided into ordinary tow chain, parallel tow chain, s type tow chain; according to the raw materials are divided into the original package plastic and recycled plastic.

(1) material: reinforced nylon, with high pressure and tensile load, good toughness, high elasticity and wear resistance, flame retardant, stable performance at high and low temperature, can be used outdoors, the amount of nylon content determines the use strength and wear resistance of the drag chain as well as the noise during operation. nylon content varies from 5% to 17%, but does not exceed 19%. it's usually about 30%.
(2) resistance: oil resistance, salt resistance, and a certain acid resistance, alkali resistance.
(3) operating speed and acceleration (the specific speed and acceleration depends on the operating condition).
