Sheffield, MA (Vocus) May 29, 2010
Sheffield Plastics, a Bayer MaterialScience LLC business based here, will feature a technologically-advanced glazing products line-up that includes new blast-resistant materials at the AIA Expo in June.
Designated Makrolon® Hygard EX, the blast-resistant products exceed the current GSA and DoD anti-terrorism force protection standards, including those with the highest defined levels of pressure loads and shock waves.
According to Karl Wiecking, Product Manager for Hygard EX, the materials afford unique performance features not available with glass systems. “When compared to laminated glass, these polycarbonate-based laminate compositions can withstand exterior blasts without splintering on the interior face of the material, “ he stated. “This eliminates the risk associated with glass fragments being projected into a room in blast conditions.”
The products have other advantage over glass systems, Wiecking added. “All Hygard EX grades carry ballistics ratings along with blast resistance. Also, they do not spall or ‘spider-web’ on ballistic or blast conditions, leaving occupants with good visibility through the glazing after impact events.”
Ken Schwartz, Sheffield’s Marketing Director, commented on other glazing technologies the company will display at the AIA Expo.
“New Makrolon MAK™ UV provides an significantly improved level of optical quality in a highly UV-resistant material for sky-lighting and other overhead applications. Relative to typical polycarbonate sheet products, MAK UV exhibits superior view-through clarity. Unlike glass and acrylic that require thermal pre-forming, the material can be formed in place for more cost-effective curved glazing installations,” he stated.
Sheffield will also show international stadium roofing applications made from its Makrolon Multiwall sheet. Available in several new configurations, the materials can reduce substructure costs substantially due to their combination of high strength and light weight compared to other roofing products, according to the manufacturer.
“Rounding out the exhibit,” added Schwartz, “will be our ballistic and containment laminates, information on companies that have developed window systems for Sheffield’s high performance materials, and our own team of international specialists for each product and application area.”
