PA Thermal Conducting Plastics Grade Magnesium Oxide
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
