What is heat shrink tube
Heat shrinkable tube is a special polyolefin heat shrinkable sleeve. The outer layer is made of high-quality and soft cross-linked polyolefin material and the inner layer of hot melt adhesive. The outer layer has the characteristics of insulation, corrosion prevention and wear resistance. The inner layer has the advantages of low melting point, waterproof sealing and high adhesion. It has the functions of high-temperature shrinkage, soft flame retardancy and insulation and corrosion prevention. It is widely used in the insulation protection of various wire harnesses, welding joints and inductors, as well as the rust and corrosion prevention of metal pipes and rods. Voltage class: 600V. Polymer materials will experience glassy high elastic state with the temperature from low to high. In glassy state, the performance is close to plastic, and in high elastic state, the performance is close to rubber. The material used in the heat shrinkable tube is glassy at room temperature and becomes highly elastic after heating. Use: during production, heat the heat shrinkable tube to a high elastic state, apply load to make it expand, and quickly cool it while maintaining expansion to make it enter the glass state. This state is fixed. As soon as it is heated in use, it will return to a high elastic state, but when the load is gone, it will retract. Shrinkage ratio: 2:1, shrinkage temperature: 84 ℃ ~ 120 ℃, working temperature: -55 ℃ ~ 125 ℃,Fire rating: VW-1

Classification of Heat Shrinkable Tubes
PVC heat shrinkable sleeve
PVC heat shrinkable sleeve has the special function of shrinking in case of heat. It can shrink when heated above 98 ℃, which is convenient to use. The products are divided into two series: 85 ℃ and 105 ℃ according to temperature resistance, with specifications Φ 2- Φ 200. The product complies with EU ROHS environmental protection directive. Used for electrolytic capacitors and inductors. The product has good high temperature resistance and no secondary shrinkage. It can be printed instead. It is used for single and combined packaging of various rechargeable batteries, and can design, print and cut for customers. It is used for covering various curtain rods, shower curtain rods, hanging rods, mop rods, broom handles, tool rods, telescopic rods, garden tools, poles and other tubular objects. It can also be used for identification, insulation and cladding of low-voltage indoor bus copper bars, connectors and harnesses. High efficiency, less equipment investment and low comprehensive cost. It is a new generation of packaging materials for lighting, led pin wrapping, guitar and packaging bottle mouth wrapping. Whether it is for civilian use, vehicle use or military use, it is the best choice.
Pet heat shrinkable tube
Pet heat shrinkable tubes (polyester heat shrinkable tubes) are much better than PVC heat shrinkable tubes in terms of heat resistance, electrical insulation and mechanical properties. More importantly, pet heat shrinkable tubes are non-toxic, easy to recycle, will not have toxic effects on human body and the environment, and are more in line with environmental protection requirements.
The environmental protection performance of pet heat shrinkable tubes is higher than the EU ROHS directive standard and can reach the Sony SS-00259 environmental protection standard. It does not contain cadmium (CD), lead (PB), mercury (Hg), hexavalent chromium (CrVI), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (pbbes/pbdes), polychlorinated biphenyls (PCB), polychlorinated terphenyls (PCT), polychlorinated naphthalene (PCN) and other grade 1 prohibited substances for environmental management. It is the coating of electrolytic capacitors, inductors and other electronic components, high-grade rechargeable batteries, toys and medical devices, and can fully meet the export requirements.
What is the purpose of the heat shrinkable sleeve?
For general electronic components and vehicle harness products, for example, when the insulation layer is required for the wire connector or the wire skin must be maintained, it is required that the raw materials are soft, resistant to sheet metal bending, and resistant to the bottom pressure of 600V. PE high-pressure polyethylene heat shrinkable pipe or pe+eva thermosol waterproof double-layer structure can be selected. Most of the rechargeable battery capacitors are made of thin, fast collapsing materials with certain wear resistance and many colors. PVC and pet heat shrinkable tubes are the best. However, other materials are likely to be torn during the whole process of application.
It specifies the characteristics of corrosion resistance, heat resistance and wear resistance, and can use fluoroplastic heat shrinkable, polyvinylidene fluoride PVDF heat shrinkable pipe, FEP heat shrinkable pipe, Teflon PTFE heat shrinkable pipe, etc.
The materials and types of heat shrinkable tubes are selected according to the main use types of heat shrinkable tubes. There is no difference between good and bad materials. The characteristics of each raw material are different, and the best is the best.
Heat shrinkable tubes made of different materials have different uses. When facing different scenes, Ningbo FBELE needs to choose different materials and sizes of heat shrinkable tubes. Therefore, the purpose of heat shrinkable tubes mainly depends on the use scene of heat shrinkable tubes, and then makes choices.
How to use the heat shrinkable tube
1. First, prepare the materials you need: a lighter, a pair of scissors, and a heat shrinkable tube.
2. Then, the prepared heat shrinkable tube needs to be sleeved on the power line.
3. Next, after the heat shrinkable sleeve is sleeved, heat the heat shrinkable tube with a lighter or heat the sleeve evenly with a high-power hot-air gun.
4. *. After the heat shrinkable tube is completely shrunk, it is completed.
2、 Precautions for use of heat shrinkable tube
1. The heat shrinkable tube and the heating equipment should not be too close. Attention must be paid to the distance between the fire and the heat shrinkable tube, i.e. 4 ~ 5cm moves evenly. When heating and shrinking, do not exceed the upper limit of temperature resistance of the heat shrinkable tube. For the heat shrinkable tube, if the temperature exceeds the upper limit of temperature resistance, our product will “melt” and return to the initial state.
2. Select a suitable heating tool. When heating and baking, the external flame of the flame forms a 45 degree angle with the surface of the heat shrinkable tube. Pay attention to moving back and forth to heat the heat shrinkable tube as a whole, slowly from one end to the other. The heating should be uniform, avoid bubbles, and ensure the shape of the heat shrinkable tube after contraction. After cooling, repair it.
Precautions for using heat shrinkable tubes
1. The heating distance and time should be controlled well, and should not exceed the upper limit of temperature resistance of the heat shrinkable tube, otherwise the heat shrinkable tube will “melt”.
2. Select a suitable heating tool. When heating, make the outer flame of the flame form a 45 ° angle with the pipe surface. Be sure to move slowly from one end of the heat storage pipe to the other end at a constant speed. After the heating pipe is cooled, trim it.
3. The heat shrinkable tubes have different heat shrinkable ratios. Pay attention to the specifications when selecting. 4. The types of heat shrinkable tubes are also different, and appropriate types need to be selected according to the actual situation.

What does customer say about FBELE Company
We saw FBELE on the forum. At that time, we thought that the enterprise’s technical articles were very thorough and in-depth, and its social responsibility was also strong. This year, we just need to have new product development, so we found fbele and asked them to purchase samples. The speed was very fast and the quality was good, waiting for the implementation of the project!
At the beginning of our new project, we encountered some difficulties because we found several other unprofessional Chinese manufacturers. Since we contacted fbele, the project has been promoted rapidly. We have to say that FBELE’s technical team is really strong. Thank FBELE’s technical team.

Genaral Questions About Heat Shrink Tube
One is DC drive, and the corresponding buzzer is active buzzer. One is square wave drive, and the corresponding buzzer is passive buzzer.
It directly affects the sound pressure of the buzzer. For the same buzzer, the higher the driving voltage, the greater the sound pressure. However, the driving voltage cannot be higher than the limit voltage borne by the buzzer, which can generally be met within 30V.
The frequency of the buzzer is determined by the buzzer cavity and buzzer blade. Theoretically, any frequency can be achieved. However, in order to facilitate users and standardize products, the more common frequencies are 2KHz and 4kHz, which are the mainstream at present.
The buzzer pin distance directly affects the assembly of the buzzer on the PCB. If the buzzer pin distance does not match the PCB hole distance, it cannot be assembled and used. The common pin distances in the industry are: 5.0mm, 7.6mm, 10mm, 15mm. When designing PCB, it is necessary to design such common pin distances.
The cavity is divided into front cavity and rear cavity. The front cavity mainly affects the frequency of the product. The front cavity is the space between the buzzer and the pronunciation hole. The larger the space volume is, the lower the frequency is, and vice versa. Generally, the intuitive response is that the larger the volume of the buzzer, the lower the frequency, and the smaller the volume of the buzzer, the higher the frequency.
