News Source : 　|　 Release Time: 2025-02-27

With the development of science and technology, modern technology for the material requirements are more and more diverse and specific. Up to now, the use of thermally conductive insulating plastics is increasing. Thermally conductive plastic using thermally conductive filler uniformly filled with polymer base material to improve its thermal conductivity, with the following product features:

1. Uniform heat dissipation, avoiding scorching point and reducing localized deformation of parts caused by high temperature.

2. Light weight, easy processing, no need for secondary processing.

3. High degree of freedom in product design, good fluidity.

The advantages of adding magnesium oxide

Zehui magnesium base has been committed to the research and development of magnesium oxide series products, including heat-conductive plastics with magnesium oxide has been widely used in the market, greatly reducing the application costs in this field. The use of Zehui magnesium oxide products can have good compatibility with thermally conductive plastics, solving the problem of brittle plastic products when adding fillers, and can effectively improve the K value of thermally conductive plastics, tensile strength, bending strength, impact strength, hardness and density and other indicators, and the fire rating can reach V0 level. At present, the magnesium oxide products produced by Zehui Magnesium Base have the advantages of good toughness, high whiteness, high thermal conductivity, moderate specific gravity, reasonable balance of flame retardant and thermal conductivity, and lower production costs. Similar additive products on the market are alumina, aluminum nitride, zinc oxide, etc. These products can be thermally conductive, but the disadvantage is that the cost is more expensive, whiteness is poor.

The significance of the study of magnesium oxide thermal conductivity

In addition, because high thermal conductivity insulating materials in aerospace and electrical equipment and other fields have a wide range of applications, in terms of electrical equipment, with the rapid growth of power demand, transmission of electrical equipment such as transformers, insulated cables, the capacity of more and more large, resulting in more and more high heat, insulating materials and therefore accelerated aging, resulting in the service life of the equipment to shrink, so to improve the thermal conductivity of the insulating materials in the power cables, to Enhance the cable core carrying capacity has important practical significance. For cable materials, insulation is important, thermal conductivity is also important.
