Characteristics of heat shrinkable tube material

KONE Electric focuses on the design, production and sales of heat-shrinkable tubes, heat-shrinkable tubes with glue, medium-thick wall heat-shrinkable tubes, high-temperature silicone/Teflon/fluoroplastic heat-shrinkable tubes, identification tubes and other casing products. The products have been Passed [RoHS2.0, UL] testing, in line with international environmental protection flame retardant standards, Wojie has a variety of heat shrinkable tube series products, and their applications are very different for different heat shrinkable tubes. Therefore, when choosing When purchasing heat-shrinkable tubing, you should choose the one that is more suitable for you according to your own needs. For those casing products with high quality requirements and strong specialties, Wojie has strong solution capabilities and advantages, complete product specifications and high technical indicators , It is widely used. The commonly used function of heat shrinkable tube is to fix the insulated wire. The insulation at the joint of the wire is the heat shrinkable tube, which is separated and has good insulation or waterproof effect. It is not common to use heat shrinkage in other places. Tube.

Since the heat shrinkable tube material is made of cross-linked polyolefin, the strength of the cross-linked molecular bond determines the selection of the heat shrinkable tube. If the degree of cross-linking is not high, you can choose a product filled with regrind. The use of plasticizers can imitate the performance of raw materials, but the shrinkage rate is not high, and the shrinkage force is not enough; those with strong crosslinking molecular bonds and large shrinkage rates need to be used for products produced with raw material button sleeves. When selecting Pay attention to the size and choose within the range of 70-80% shrinkage of the heat shrinkable tube.

Next, we will further understand the button casing market based on the performance and use of heat shrinkable tubing.

KONE electric heat shrinkable tubing has the properties of high temperature shrinkage, soft flame retardant, insulation and corrosion resistance, and is widely used in insulation protection of various wiring harnesses, solder joints, and inductors, and rust and corrosion protection of metal tubes and rods. As the polymer material undergoes a glassy-high elastic state as the temperature goes from low to high, the performance of the glassy state is close to that of plastic, and the performance of the high-elasticity state is close to that of rubber. Therefore, the material used in the heat shrinkable tube is glassy at room temperature and becomes highly elastic after heating.

In the production process, the heat shrinkable tube is heated to a highly elastic state, and the heat shrinkable tube is expanded by applying a load, and the heat shrinkable tube is quickly cooled while maintaining the expansion, and then the heat shrinkable tube will enter Glass state, that is to say, this state is already fixed. When we heat it when we use it, the heat-shrinkable tube will return to a highly elastic state when heated. At this time, there is no load, and the heat-shrinkable tube is It will retract, which is the principle of use of heat shrink tubing.

Heat-shrinkable tubing has now penetrated into various fields, and more and more places are used for heat-shrinkable tubing. Only by understanding the performance and working principle of heat-shrinkable tubing can the heat shrinkage be better used in the future. The role of the tube, KONE Electric heat shrinkable tube has a wealth of experience, since the establishment of the company, after continuous innovation and development, the company's heat shrinkable tube products have been praised by the majority of users, the company is based on "integrity-based, service-oriented" The principle is to provide high-quality and reliable products and services for the majority of users wholeheartedly.
