Industry standards and performance indicators of heat shrinkable tubing

With the continuous innovation and development of Heat Shrinkable Tube technology and the improvement of the industry's own requirements, there is a higher pursuit of the quality of heat shrinkable tubes. There are also industry standards and express regulations. In the past, only heat shrinkable tubes had insulation properties. , but now the domestic emphasis on product safety and environmental protection has higher requirements for the heat shrinkable tube industry, which is also forcing the progress of the industry. As a common insulating sleeve, heat shrinkable tubing is one of the important materials in the electrical, electrical, and wiring harness industries.

Among all the colors of heat shrinkable tubes, black is the most commonly used, and its performance is quite different from that of colors (red, blue, yellow, green, white, transparent). This is mainly reflected in the flame retardancy of heat shrinkable tubes. Black thermal The flame retardancy of the Shrink Tube is the best. Due to the addition of color accessories, the proportion of flame retardant is relatively reduced, and the flame retardancy of the color heat shrink tube will be slightly lower than that of the black one. Color heat shrink tubes are generally used for marking cables. ID tube use.
In fact, black heat shrinkable tubes are also divided into two types: flame retardant and non-flame retardant. The flame retardant type is matte, and the non-flame retardant type is brighter in color, as if coated with a layer of oil stains. It is relatively easy to distinguish.
Everyone knows that there are many colors of heat shrinkable tubes. Commonly used heat shrinkable tubes are black and white, and there are transparent heat shrinkable tubes. In general, we refer to colors other than black as color heat shrinkable tubes. Heat shrinkable tubes have Black, white, red, blue, green, yellow, gray, orange, purple, brown, yellow-green heat-shrinkable tubes, plus a transparent heat-shrinkable tube, a total of 12 conventional colors, most of these colored heat-shrinkable tubes It is in stock. If it is not in stock, it needs to be customized. Special colors other than these 12 colors can also be customized, but generally there is a minimum order quantity requirement, and the size of MOQ will vary according to different specifications. Well, we have a general understanding of the new knowledge about the color of heat shrinkable tubes. So, will the performance of these heat shrinkable tubes with different colors be different? Are they all the same price? Below, we will answer your questions in three points.
First of all, the price is different. Generally, we use black as the base price. Heat shrinkable tubes of other colors are 8-10% more expensive than black, but this is not absolute. There are several colors that are special, and we will list them separately. For example: orange heat shrinkable tube, purple heat shrinkable tube, brown heat shrinkable tube and yellow-green heat shrinkable tube, these are relatively special colors, and the price of the sleeve needs to be calculated separately.
Second, the performance is different. Most of the heat shrinkable tubes can achieve the same performance from flame retardant to pressure resistance. There is a special existence in it, which is the transparent heat shrinkable tube. The transparent heat shrinkable tube is inherently halogen-free and red. Phosphorus heat shrink tubing.
Third, the application industries are different. Colored heat-shrinkable tubes are used in all walks of life. Orange heat-shrinkable tubes are generally used in the new energy vehicle industry, while yellow-green heat-shrinkable tubes are mainly used in the electrification field for grounding marks.
The above content tells you a new knowledge, that is, the color of the heat-shrinkable tube is not only for the appearance, but also affects the performance index of the heat-shrinkable tube. I hope you pay attention to the selection when using the heat-shrinkable tube. Wrong casing, causing unnecessary losses!
