PA Thermal Conducting Plastics Grade Magnesium Oxide

by Hu Yanchao Magnesium oxide manufacturers in China

Thermal plastic: the thermal filler is used to evenly fill the polymer matrix material to improve its thermal performance. The thermal conductivity is mainly measured by the thermal conductivity coefficient (unit: W/m.k).

  Thermally conductive plastics are divided into two categories: thermally conductive plastics and thermally conductive insulating plastics. The main components of heat-conducting plastics include matrix materials and fillers. The matrix material includes PPS, PA6/PA66, LCP, TPE, PC, PP, PPA, PEEK, etc.

  Fillers include AlN, SiC, Al2O3, graphite, fiber-shaped carbon powder with high thermal conductivity, scaly carbon powder with high thermal conductivity, etc.

  Product features

  (1) evenly dissipate heat, avoid hot spots, and reduce local deformation of parts caused by high temperature

  (2) light weight, 40-50% lighter than aluminum

  (3) the forming process is convenient, without secondary processing

  (4) high degree of freedom in product design

  (5) since the molding method is mainly mold injection molding, the rubber material flows into the mold through pressure after heating, and then goes through cooling molding.

  The characteristics of the processing technology make the thermal conductivity of the molded material show the anisotropic characteristics, that is, the in-plane direction of the flow of the rubber during the injection and the through-plane direction of the vertical flow of the rubber.

In general, the thermal conductivity in the direction of plastic flow is 3 to 6 times that in the direction of vertical plastic flow. This difference is caused by the plastic forming in the direction of injection molding, which tends to form a continuous molecular chain. In PA,PP,PES, the addition of 40-50% magnesium oxide can greatly improve the thermal conductivity of plastics.

Mei Shen is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.

Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.

Hebei Mei Shen Technology Group is the main magnesium oxide producer in the world. It is also the largest magnesium salt producer in China and has won the ISO9002 quality system certification. It also has GMP-Certification.

With rich experience in the research, development, production, management and operation of magnesium oxide products, Mei Shen Group has always attached great importance to the research and development of new products and strict requirements on product quality.MeiShen has a high-level sales team. The business covers more than 20 countries and regions around the world.It is widely welcomed by new and old customers.
