*This list of typical physical properties
is intended for basic characterization of
the material and does not represent specific
determinations of specifications. The physical
properties values reported herein were determined
on compression molded specimens prepared
in accordance with procedure C of ASTM D
1928 and may differ from specimens taken
from pipe.
**The Shore Hardness listed data was determined
on press molded test specimens and may,
therefore, vary from specimens taken from
the manufactured product.
