Product profile

HL- 200 is made of polycrystalline wool（PCW*）. By using this type of ceramic fiber, HL- 200 can maintain strong structure and excellent durability at high temperature （lower than 1250℃）, also will improve erosion resistance, there is no need to add extra edge protecting material or measures. The PCW fiber is an non-hydrophilic material and it will not be affected by oil, water or urea in real applications.

Due to the excellent bending performance of HL-200, HL-200 is easy to wrap or shape. HL-200 is easy for canning, no matter stuff mounting, tourniquet mounting or other mounting methods. HL-200 can be applied in different catalytic converters that including the exhaust system of gasoline, diesel（SCR/DPF/DOC/ASC）and natural gas applications.

The classification of PCW fiber belongs to environmental friendly material, therefore HL- 200 can be used in Europe, the United States, Japan and other markets around the world.
