Sumitomo Chemical's DPF Adopted by Passenger Car Maker

Dec. 15, 2014

Sumitomo Chemical announced that the Company’s aluminum titanate-based diesel particulate filter (DPF) will be used in passenger cars for the first time. Sumika Ceramics Poland Sp. z o.o., a wholly-owned subsidiary of Sumitomo Chemical, will
produce and supply the DPFs, beginning 2015.

Amid growing environmental awareness, many countries around the world have been tightening their exhaust gas emissions regulations in recent years. In Europe, among other regions, the Euro6 emissions regulation, one of the strictest in the world, took effect in September this year, mandating the mounting of DPFs as standard equipment on diesel-powered vehicles in Europe as a means to meet standards for restricted particulate emissions. As the regulations will grow intensified going forward, such mandatory requirements are likely to extend to commercial and off-road vehicles, too. Given the situation, the DPF market is expected to grow much further, heightening needs for higher-performance DPFs.

Sumitomo Chemical has developed its DPF, marketed under the SumipureTM brand name, by capitalizing on its technological expertise cultivated in-house through the business of inorganic materials, such as alumina products. The DPF, made of aluminum titanate, shows excellent properties, such as thermal shock resistance (*1) and mass limit (*2) with respect to soot from internal-combustion engines in automobiles and other machinery.

Aiming to expand its DPF business further, Sumitomo Chemical has already started supplying samples of a DPF suitable for selective catalytic reduction (SCR) coating (*3) and a particulate filter for gasoline-engine vehicles, both of which are expected to come into wide use in the future.

  1. The DPF’s property to withstand rapid changes in temperature at the time of undergoing functional regeneration through incineration of trapped soot.
  2. The amount of soot that can be continuously filtered.
  3. The DPF capable of removing nitrogen oxides as well as soot.
