What is the relationship between the performance of PP Zipper Braided Sleeve

First of all, take double 24 industrial-grade PP Zipper Braided Sleeve as an example, each of its performances is closely related to another performance, and these hidden connections are difficult to understand, so we will introduce them one by one according to customer requirements. reveal.

1. Density: PP Zipper Braided Sleeve and any foaming products and an important performance, the current mainstream density in the market is between 0.3 and 1.0, and the density of conventional non-foaming is stably controlled at 1.2. This is one of the connections. In addition, the density of foamed products will directly affect the final unit price of the product. The higher the foaming density, the higher the unit price will be. Therefore, before considering using PP Zipper Braided Sleeve, you must be careful. The density should not be too high or too low. It is recommended to use PP Zipper Braided Sleeve grips for bicycles and fitness equipment grips for this type of product. You can choose a density between 0.5 and 0.7, while industrial cable casing Insulation Tubes and high temperature resistant PP Zipper Braided Sleeve are also sealed. The density used is between 0.3 and 0.5. As mentioned earlier, the density of conventional Cable Sleeve is 1.2, and the hardness will be a little harder, while the PP Zipper Braided Sleeve decomposes the density of 1.2 into 0.3~1.0 through a special process, and then becomes a spongy Cable Sleeve. Does the hardness of the product become soft? ?
It can be seen that the higher the foam density, the higher the hardness, and the hardness cannot be adjusted under the premise of controlling the density, that is to say, the hardness will also increase with the increase of the foam density, and the hardness will definitely decrease when the density decreases. Therefore, it is concluded that the density of PP Zipper Braided Sleeve will be related to the final price, applicable environment, and hardness, and it is a matter of affecting the whole body.
2. Hardness: first of all, the hardness unit used by PP Zipper Braided Sleeve is different from that of conventional cable casing tubes. The former uses Shore C and the latter uses Shore A. The two are mutually compatible. In other words, after the cable casing is foamed, it will be spongy and the hardness will be relatively low, so Shao C is used. Secondly, the relationship between hardness and density is interrelated, one of them rises and the other hardness also rises, and the plus or minus deviation of the hardness of PP Zipper Braided Sleeve will be 1~3° larger than that of non-foaming products. When the hardness is not easy to control, most of them are within the normal range of ±5~6°, and the testing equipment also needs to be tested with a hardness tester for silicone rubber. Other testing equipment cannot be used in the field of cable casings. PP Zipper Braided Sleeve If it is round, it needs to be cut with scissors and placed on a flat surface for extrusion testing, or filled with a round plug so that it has enough support to withstand the pressure from the hardness monitor to test the hardness of the product.
It can be said that PP Zipper Braided Sleeve are one of the uncommon products, and the close relationship between various properties will continue to be analyzed.
