It has good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and is an ideal heat dissipation material and high temperature insulating material. Boron nitride has good chemical stability and can resist the corrosion of most molten metals. It also has good self-lubricating properties. Boron nitride products have low hardness and can be machined. Adopt high-temperature boron nitride raw materials with international advanced technology to ensure material purity and high temperature resistance. Adopt cold isostatic pressing and hot pressing sintering process of bidirectional pressing, the material has high density and long service life. Stable and mature production technology and process, without adding any binder, to ensure material stability.
