Magnesium Oxide Used In PA Thermal Conductive Plastics
High-purity magnesium oxide used in PA thermal conductive plastics
Thermally conductive plastics: Use thermally conductive fillers to
uniformly fill the polymer matrix material to improve its thermal conductivity.
The thermal conductivity is mainly measured by thermal conductivity (unit:
W/m.k).
Thermally conductive plastics are divided into two categories: thermally
conductive and electrically conductive plastics and thermally conductive and
insulating plastics.
The main components of thermally conductive plastics include matrix
materials and fillers. Matrix materials include PPS, PA6/PA66, LCP, TPE, PC,
PP, PPA, PEEK, etc.; fillers include AlN, SiC, Al2O3, graphite, fibrous high
thermal conductivity carbon powder, scaly high thermal conductivity carbon
powder, etc.
Product Features
(1) Uniform heat dissipation, avoid hot spots, and reduce local
deformation of parts due to high temperature
(2) Light weight, 40-50% lighter than aluminum
(3) Convenient forming and processing, no need for secondary processing
(4) High degree of freedom in product design
(5) Since the molding method is mainly injection molding, the rubber
material flows into the mold under pressure after heating, and then is cooled
to form. The characteristics of the processing technology make the thermal
conductivity of the material after molding show anisotropic characteristics,
that is, the in-plane and through-plane directions of the rubber flow during
injection molding. Generally, the thermal conductivity in the rubber flow
direction is 3 to 6 times the thermal conductivity in the vertical rubber flow
direction. This difference is caused by the easy formation of continuous
molecular chains in the flow direction of the rubber during injection molding.
In PA, PP, PES, adding 40-50% magnesium oxide can greatly improve the
thermal conductivity of the plastic.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.
