The Main Difference Between Yellow Wax Tube And Pre-insulated Casing

pre insulated sleeve is a necessary insulating material for industries such as motors and electrical equipment. Since the two have similar appearances and similar performances, many users cannot tell the main difference between them. Today, the editor will explain the performance differences between the two in detail so that everyone can better understand and use such products.
Yellow wax tube (polyvinyl chloride glass fiber hose) is an electrical insulating paint tube woven with alkali-free glass fiber and coated with polyethylene resin after plasticization. Yellow wax tube combines the superior properties of most plastics, impact resistance, low temperature resistance, wear resistance, chemical corrosion resistance, self-lubrication, and impact energy absorption. These six characteristics are the highest values ​​currently possessed by plastics. This new type of plastic product is widely used in Europe and the United States, and the demand is increasing. Similarly, in my country, ultra-high molecular weight yellow wax tube products are also increasingly widely used. Ultra-high molecular weight yellow wax tubes use Ziegler-type high-efficiency catalyst low-pressure synthesis method, and the molecular weight is controlled at 1.5-3 million or more as needed. Considering the thermal degradation of molecules during the processing process, yellow wax tubes made with a molecular weight greater than 1.7 million have more superior performance.

pre insulated junction sleeve is made of glass fiber yarn woven into a tube, which is then impregnated with silicone resin and cured in a high-speed polymerization device that integrates light, electricity and heat. The product is light and hard, non-conductive, high in mechanical strength, anti-aging, high temperature resistance, and corrosion resistance. Since the glass fiber casing is made of alkali-free glass fiber yarn and silicone resin materials, it can effectively resist the corrosion of media such as acid, alkali, and salt, and the erosion of chemical wastewater and many chemical liquids. Under normal circumstances, it can maintain safe operation for a long time. The glass fiber tube can be used for a long time in the temperature range of -40℃~70℃, and the specially formulated insulated joint sleeve can work in a high temperature environment above 200℃ for a long time.
In summary, in addition to the insulation performance of the yellow wax tube, the glass fiber casing also has high and low temperature resistance that the yellow wax tube does not have. Fully understanding and recognizing the main performance and differences of the glass fiber casing and the yellow wax tube can better choose the best product partner and better serve the product!
