What is SiC?

The BM Catalysts Premium range of DPFs is made using silicon carbide as opposed to cordierite which is used in the standard range of DPFs. Also known as Carborundum, it is a material widely used in applications that require a high thermal or strength endurance. It is mass produced as a powder that which can be bonded together using heat to form a ceramic.

What are the properties of SiC DPFs and why are they a premium product?

  • 3 year warranty
  • 99% filtration efficiency
  • Higher melting point (2700°C)
  • Higher thermal conductivity
  • Low thermal expansion
  • Thermal shock resistant
  • Does not melt at any known pressure
  • More resistant against monolith fractures
  • Corrosive resistant
  • One of the strongest known materials – second to diamond

Why we use SiC in our Premium Range

It has a melting point of 2700°C so is extremely unlikely to melt during Regeneration. It has to be made from small segments fixed together with a special cement to enable it to cope with heat expansion. It also boasts a 99% filtration efficiency as is commonly used in O.E DPFs.
