What is causing the lack of elasticity in Nomex Braided Sleeve?

The material of the Cable Sleeve itself is very elastic, so we often see that some manufacturers use Nomex Braided Sleeve to make elastic tubes, tension rings, tension sheets and other fitness products.

But there are also some Nomex Braided Sleeve that have insufficient elasticity due to various reasons. For raw materials, ordinary Cable Sleeve also have some problems, such as substandard service life, poor toughness, and insufficient rebound. So what are the reasons for the lack of elasticity of Nomex Braided Sleeve?
First of all, when too much silicone oil and silica are added to the raw material of the Cable Sleeve, the performance of the product will be confused. Secondly, the silicon atoms in the silicone resin are destroyed, and if the softness decreases, there will be a sticking phenomenon, and the softness and fluidity will not be good, resulting in a decrease in the tensile strength of the product after high-temperature molding. The product will not be reflected after the production is completed, but after the process After a period of use, under the conflict of various environments, the product will gradually deform, the rebound rate will decrease, and the product will stick.
Finally, in the Nomex Braided Sleeve molding process, the debugging and coordination of the machine have a certain influence. Sometimes in the vulcanization process, in order to increase the output and increase the production efficiency, the staff shorten the vulcanization time and the products released from the mold will appear soft. When increasing the output, the temperature must be increased to reach a certain equilibrium rate under the premise of reducing the time, otherwise the product will have various adverse phenomena, and if the production time is too long, the product will be too brittle and will be torn if it is stretched. It is recommended to produce Properly control the time and vulcanization temperature of the product during the process.
In short, in the production process, except for several factors such as machine, raw materials, man-made, and environment, the toughness of Nomex Braided Sleeve will not cause quality problems, so Nomex Braided Sleeve manufacturers control these factors in the production process, There will be basically no problems with the quality of the product.
