PBN strips are used in a wide range of applications in the semiconductor, aerospace, and defense industries. Pyrolytic Boron Nitride strips are made by depositing boron nitride onto a substrate by Chemical Vapor Deposition (CVD) at high temperatures and low pressures. PBN strips have excellent thermal stability and high thermal conductivity and are ideal for high-temperature applications such as insulation and furnace.

PBN strips can withstand temperatures up to 1,800°C in a vacuum environment and 1,500°C in an oxidizing atmosphere.

In addition to high-temperature resistance, the PBN strips have a low coefficient of thermal expansion (CTE) and excellent electrical insulation properties. These properties make them ideal for applications where dimensional stability and electrical insulation are critical, such as in the production of semiconductor wafers.

Available in a variety of thicknesses and widths, PBN strips can be easily cut, drilled, and machined into customized shapes and sizes to meet specific application requirements.

Pyrolytic Boron Nitride Strip Applications

PBN Strip from Edgetech Industries Ceramics Division can withstand high temperatures in high vacuum environments, it has excellent corrosion resistance and electrical resistance. Based on the above excellent properties, Pyrolytic Boron Nitride Strip is an ideal choice in a wide range of industries, such as:

-Used in the semiconductor, aerospace, and defense industries

-High-temperature applications such as insulation and furnace

-Used in the production of semiconductor wafers

Packing

As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Pyrolytic Boron Nitride Strip is carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used for PBN products, vacuum packing is also engaged for some of the parts.
