DuPont™ SentryGlas® Interlayer Helps Strengthen Shanghai Oriental Pearl Tower
All-glass “Skydeck”


On May 1, the all-glass “Skydeck” observation platform of the Shanghai Oriental Pearl TV Tower, one of the landmarks in Shanghai, was opened to public as another tourist attraction in the city.  Located in the tower’s second sphere structure which is 290 meters above the ground level, the Skydeck’s 700m² glass flooring is made with laminated glass containing DuPont™ SentryGlas® interlayer.  

Being widely used in laminated glass constructions, SentryGlas® safety glass interlayer is 100 times stiffer and 5 times tougher than conventional PVB interlayers.  Contributing to real safety, glass laminates made with SentryGlas® provide superior strength to tolerate high stress loads and an excellent post-breakage performance.  In addition, because of its outstanding clarity, SentryGlas® interlayer offers excellent transparency to glass.

The adoption of SentryGlas® in the Shanghai Oriental Pearl Tower renovation project resulted from the joint efforts of DuPont Building Innovations and Glass Laminating Solutions in promoting the products in China.  Another success out of the collaboration between the two businesses is the application of 10,000m²SentryGlas® interlayer used in part of the glass curtain-wall for Shanghai Expo Center, one of the permanent exhibition centers for the 2010 Shanghai World Expo.

“Global economic recession dramatically affected the construction industry in China.  We, however, carried out a thorough market research and found that the development of commercial and governmental constructions was relatively stable because of the government’s fiscal stimulus plan”, said Wang Xin, general manager, DuPont Building Innovation, China.  We are implementing the directive of ‘fighting for every customer order’ by working closely with various business units within DuPont and directly promoting DuPont construction offerings to design houses and property developers through our marketing representatives.” 

“The applications of SentryGlas® interlayer in the Shanghai Oriental Pearl Tower and Shanghai Expo Center are wonderful recognition of the DuPont brand and products.  To explore the substantial market potential in China, we will further strengthen our efforts to promote SentryGlas® interlayer in local market,” said Florence Lin, Greater China Sales and Marketing Manager -- Glass Laminating Solutions.

DuPont™ SentryGlas® has been used in many famous landmark buildings in China, including the Shanghai Oriental Art Center, the National Indoor Stadium, the Shenyang Henglong Square and the 660-meter-high Guangzhou TV Tower which is under construction, just to name a few.
