The role of magnesium oxide in thermal conductive plastics

Thermal conductive plastic is a new type of industrial material that uses thermal conductive fillers to uniformly fill polymer matrix materials, used to improve thermal conductivity.

1、 Overview of thermal conductive plastics
         Thermal conductive plastic is a new type of industrial material that uses thermal conductive fillers to uniformly fill polymer matrix materials, used to improve thermal conductivity. The thermal conductivity is mainly determined by the thermal conductivity coefficient. Due to the increasing requirements for the thermal conductivity of equipment in recent years, such as the thermal conductivity coefficient and long-term thermal stability of thermal conductive materials, research and development of thermal conductive materials are crucial. With the continuous penetration of thermal conductive plastic products in downstream fields, the market size of thermal conductive plastics is also constantly increasing. This trend also provides great opportunities for the development of thermal conductive materials.

2、 Classification of thermal conductive plastics
          Thermal conductive plastics are mainly divided into two types: synthetic and filled.
1. Synthetic thermal conductive plastics: Polymers with complete crystallization and thermal conductivity achieved through phonons belong to the category of synthetic polymers with high thermal conductivity.
2. Filling type thermal conductive plastic: Fill the polymer with high thermal conductive filler particles, fibers, layers, etc.
Among them, filled thermal conductive plastics can be divided into two categories: thermal insulation plastics with lower thermal conductivity (around 1.5W/m.k) and thermal conductive plastics with higher thermal conductivity (5.0W/m.k or even higher).
3、 The role of magnesium oxide in thermal conductive plastics
          Magnesium oxide, as a commonly used chemical in thermal conductive plastics, has excellent thermal conductivity and flame retardancy, and is widely used in thermal conductive plastics. Adding magnesium oxide to thermal conductive materials will give them the characteristics of light weight, easy processing and molding, and low finished product cost, which also makes magnesium oxide play a crucial role in the thermal conductive plastic industry. However, the type, content, particle size, thermal conductivity, mechanical properties, and other related factors of magnesium oxide directly affect the thermal conductivity of thermal conductive plastics. Therefore, special attention should be paid to the selection of magnesium oxide, and high-purity magnesium oxide with high purity, small particle size, good whiteness, good dispersibility, and uniform particle size under the Zehui magnesium based brand can greatly improve the thermal conductivity of thermal conductive plastics.
