With the rise of new energy vehicles, is there a high chance of using silicone rubber materials?baby silicone bibs price

　　The times are constantly developing and reforming, and the routes they take are also different. Just like the gradual rise of the new energy vehicle industry, which is linked to the development of environmental protection and green, which is developed for the purpose of reducing pollution and maintaining the world's environment, and silicone rubber products are officially moving towards Starting from this direction, it is used by a wide range of industries. In addition to industrial buildings and daily use, it is also indispensable in automobiles and modern new energy vehicles!

　　An important part of the new energy vehicle is the high-voltage wire and cable of its power part, which is responsible for transmitting current from the battery end to the electric drive components, and delivering the power source of the new energy vehicle. For this reason, the main difference between this type of cable and ordinary car cable is: transmission of high voltage and high current: the voltage can reach 600V, the instantaneous voltage can reach 1500V, and the current can reach 300A; The layout space is limited, and there are many bends when arranging; the cable generates a large amount of heat, and the cabin environment is complex. The impact of the engine on the cabin also needs to be considered for hybrid vehicles; the low temperature environment of the cable also needs to be considered in extremely cold regions. .

　　Based on the characteristics and use environment of new energy vehicle cables, corresponding requirements are also put forward for the manufacturing materials of new energy vehicle cables. For insulation and sheath materials, good high and low temperature resistance, excellent bending resistance and resistance are required. tearing performance, etc. At present, the most widely used materials in the industry are cross-linked polyolefins, thermoplastic elastomers and silicone rubber products. Among them, the good high and low temperature resistance, voltage resistance and flexibility of the silicone rubber sheath make this material very suitable. product requirements.

　　Silica gel is a thermosetting material, and the cross-linked product will not melt under high temperature. Its long-term high temperature resistance can reach 180 degrees Celsius, and it can be raised to more than 200 degrees Celsius after adjusting the formula. Low temperature resistance can reach minus 50 degrees Celsius, and special products can reach minus 120 degrees Celsius. Silicone rubber also has good insulation properties, and its breakdown voltage is above 20KV/mm, which can help cables maintain good insulation and stability.

　　On this basis, silicone rubber can also provide excellent mechanical properties, such as high tear strength, high tear resistance silicone rubber can make up for the weak point of conventional silicone rubber tear strength, tear strength can reach 40N/ mm or more, the elongation at break can reach more than 500%. Such a material can provide the cable with good bending and turning ability, helping the cable to be densely arranged in a small space.

　　Based on the requirements of such products, WACKER CHEMICALS has launched the platinum vulcanized silicone rubber product ELASTOSIL@Rplus4305/70K1CN, which has the following notable features:

　　As an excellent high temperature resistant insulating material, silicone rubber products also provide excellent mechanical properties. While escorting wires and cables, they are also doing their best for my country's new energy vehicle business.
