Special features:

1)OR-300 grade has excellent resistance to the toughest oil application such as oil-treated coal. petroleum base oils.

2)OR-200 is grade has superior oil resistance to various kinds of animal and vegetable oil with severe cold temperature up to -45’C.

3)OR-100 grade is to resist to moderate oil resistant operations like wood chips, linseed . Cottonseed and whole soybeans where static conductivity is needed.

4) HTN grade is recommended for conveying hot asphait with temperature up to 175’C where both oil & heat.
