There are many types of heat shrink tubing, and the performance of each type of heat shrink tubing is different. Therefore, you must first understand the performance and uses of various types of heat shrink tubing before you can choose the appropriate model more quickly. Commonly used heat shrink tubes are divided into ordinary low-voltage insulating heat shrink tubes, sealed waterproof heat shrink tubes, oil-resistant and high-temperature heat shrink tubes, and high-voltage cable heat shrink tubes according to their uses. Then you can choose the corresponding heat shrink tube according to your own use environment and product technical requirements.

1. Low-voltage insulating heat-shrinkable tube refers to a heat-shrinkable tube with a rated voltage of 600V. It can be used as an insulating protection sleeve with a voltage of 600V. Low-voltage insulating heat-shrinkable tube can be used for the insulation protection of general resistors and terminal solder joints.

2. Sealed and waterproof heat shrinkable tube means that the inner wall of the heat shrinkable tube has a layer of sealed and waterproof hot melt adhesive, which can achieve the function of sealing and waterproofing. According to different wall thicknesses, it is divided into three types: double-walled heat-shrinkable tube with glue, thick-walled heat-shrinkable tube with glue, and heat-shrinkable tube with 6 times high shrinkage ratio.

1. Double-walled heat-shrinkable tubing with glue is relatively soft, and the wall thickness is generally about 0.5-0.8mm. It is usually used for sealing at the end of wiring connections in automobiles and electronic fields to prevent water vapor from corroding components.

2. Thick-walled heat-shrinkable tube with glue is a thickened heat-shrinkable tube with glue. It is also a double-layer structure with hot melt glue on the inner wall. The unique wall thickness advantage of thick-walled adhesive heat shrink tubing makes it very wear-resistant. It is often used for the outer insulation sealing and waterproofing of buried cable joints, as well as the outer protection of various pipes to prevent pipes from rusting and corroding and extending their service life.

3. 6 times high shrinkage ratio heat shrinkable tube has a shrinkage ratio of up to 6 times. From the original aperture of 19.1, it can shrink to a minimum aperture of 3.2. The shrinkage ratio is very amazing and is often used for products with very large outer diameter spans.

3. Oil-resistant and high-temperature-resistant heat shrinkable tubes are also very easy to understand. They are heat-shrinkable tubes that can protect themselves in oil and high-temperature environments for a long time. There are three main types of Teflon heat-shrinkable tubes that are oil-resistant and high-temperature resistant. Shrink tubing, fluororubber heat shrink tubing.

1. Teflon heat shrink tubing has the best high temperature resistance in the field of heat shrink tubing. It can work stably in a high temperature environment of 260°C, does not soften or drip, and has strong resistance to acid and alkali solutions. It is widely used in the aerospace field, so for products with very high temperature requirements, just choose Teflon heat shrink tubing.

2. The rated temperature of fluororubber heat shrinkable tube can be stabilized at 200°C, and it does not corrode in high-temperature oil. It has excellent resistance to fuel, hydraulic oil, lubricating oil, etc., and is often used in aircraft or vehicle engines that require high temperature resistance and oil resistance. Protection of cable harnesses near the fuel tank.

4. High-voltage cable heat shrinkable tubes generally refer to 10KV-35KV high voltage heat shrinkable tubes. They are usually used for the insulation protection of busbars or busbars, so they are also called busbar heat shrinkable tubes. They are divided into two types: 10KV and 35KV according to voltage levels. , you can choose 10KV or 35KV busbar heat shrinkable tube according to your own voltage level.

    According to the introduction of the editor of DUWAI heat shrink tube manufacturer, the choice of heat shrink tube model is very simple. You must first clarify the technical design requirements of your product, and then match the corresponding heat shrink tube according to the technical requirements. If you are also ambiguous, you can Just contact the DUWAI heat shrink tube manufacturer directly, and professional technicians will match the corresponding models and specifications for you.
