VALLEY FORGE, Penn. (October 1, 2003) – Saint-Gobain Vetrotex
has developed new glass reinforcement products that are compatible
with phenolic resins in pultrusion processes. A continuous filament
mat and a direct roving are designed specifically for phenolic applications,
offering high affinity to and compatibility with phenolic resins.
“The exceptional fire resistance of phenolic resins provides
new opportunities for the use of composites in transport, building,
and industrial, to name a few. Saint-Gobain Vetrotex is committed
to helping to grow the use of phenolics in a growing number of demanding
applications,” said Dave Eberhart, Director of Marketing.
UNIFIRE® reinforcement is an E-glass continuous strand filament
mat of random orientation in multiple layers and held together by
a phenolic binder. The pure phenolic binder confers exceptional fire
resistance properties to the pultruded profile. Thanks to this excellent
affinity with phenolic resins, UNIFIRE reinforcement offers a very
fast and complete wet-out. The outstanding tensile strength of the
impregnated mat permits line speeds of up to 24-in/min. (55cm/min.)
with no mat tears. Tests have demonstrated that with UNIFIRE mat it
is possible to achieve superior transversal mechanical properties
on the pultruded profiles. UNIFIRE reinforcement is available in different
weights: 1.0 oz/ft, 1.5 oz/ft and 2.0 oz/ft. Width can vary from 20''
(50cm) up to 118'' (300cm).
69D direct roving is a high performance single end, zero catenary
reinforcement designed for filament winding and pultrusion with phenolic
resin systems. 69D direct roving gives superior mechanical properties
and uniform appearance in phenolic pultruded profiles. Important characteristics
are very low fuzz generation and outstanding compatibility with phenolic
resins. 69D roving is produced in yields of 113 and 250 yards per
pound. |
