With the unique combination of physical and chemical properties of boron nitride, boron nitride has the following advantages in the field of aluminum mold release agent:
· Low friction coefficient -- soft and smooth, no friction at high temperature;
· Nnlike graphite carbon black, the surface defects of boron nitride can be minimized and the traces left on the profile are not obvious
, high temperature resistant - 900 ℃, the highest tolerance in the air of inert gas in the highest resistance 2000 ℃;
· Clean and white appearance
· Excellent corrosion resistance, non-wetting in contact with molten metals;
· Excellent inertia, non-flammable, non-toxic, safe storage and use process;
· Excellent electrical insulation, reducing short-circuit risk of equipment;

· less consumption of demoulding agent per cycle.

  Used for aluminum, magnesium, zinc and other alloy casting, gravity/low pressure casting, forging, powder metallurgy and other fields.It is widely applied on the surface of flow groove, distribution flow groove, lining of casting platform, filter box, transfer plate, casting and rolling nozzle material, slag skimmer, pouring bag and other materials to protect the mold against corrosion and extend the service life of refractories. At the same time in the production process, to prevent the penetration of fine impurities into the metal liquid, secondary pollution, greatly improve the quality of products.It has excellent lubricity and oxidation resistance under high temperature environment. The special physical and chemical characteristics of boron nitride are used to protect its special lubricity, non-sticking, anti-sticking and anti-corrosion oxidation of metal or graphite even at extremely high temperature.
