RAMCO® SpraGard® Safety Shields, the work horse of safety shields, are most frequently specified because of their wide range of physical characteristics.
RAMCO® Spra-Gard® Safety Shields are fabricated in three proprietary thermoplastic textiles:
– Teflon* (tetrafluoroethylene or TFE coated fiberglass)
– Polypropylene (PPL)
The two woven cloths — TFE and PPL —are developed exclusively for RAMCO® according to specifications. These fabrics are produced to a patented design and a “porosity concept’’ that has been very carefully engineered. Rather than using impenetrable fabrics, Spra-Gard® Safety Shields are made of slightly porous textiles — too slight to permit a sprayout but sufficient to allow fluid to seep through to the indicating patch in the event of a leak.
ECTFE, a fluoropolymer clear film, is the material that forms the wide center band of the Spra-Gard® “See-Thru” Shields. This non-flammable film withstands temperatures up to 300°F (150°C) and has very high tensile strength. It also demonstrates excellent chemical resistance.
All Spra-Gard® Shields have been subjected to ultraviolet (UV) testing and have performed without degradation for approximately 500 hours.
