SUPERFLEXON is a plastic material made of a rigid combination of
polyolefin and fibrous inorganic components. It is chemically inert
and normally unaffected by moisture, corrosion and the effects of
temperature changes. SUPERFLEXON also has a high tensile strength
with light weight because it is a solid (not foamed) structural material.
SUPERFLEXON covers are NOT traffic covers and should not be used
in roadways, etc.
