VALLEY FORGE, Penn. (October 1, 2003) –
Saint-Gobain Vetrotex has enhanced a high-performance fiberglass reinforcement
for pultrusion and filament winding. Newly modified RO99®-673
roving offers improved mechanical properties and an enhanced ability
to withstand handling with no change in processing characteristics
with polyester, vinylester, and epoxy resin systems.
Advances in sizing chemistry have produced improved mechanical properties
in pultruded profiles, including flexural strength (ASTM D790), compression
strength (ASTM D695), and horizontal shear (ASTM D-2344).
In addition, enhanced RO99-673 offers improved roving compression
resistance. This reduces damage caused by shipping, stacking, and
handling, resulting in more consistent pay-out.
RO99-673 is a single-end, zero-catenary reinforcement designed specifically
for pultrusion of structural shapes and filament winding of tubes,
pipes, tanks, and similar hollow products. RO99-673 is available in
roving yields ranging from 56 to 675 yd/pound.
