Egypt Pavilion Meets China World Expo Fire Regulations

09 July 2010

The Egypt pavilion currently on display at the China World Expo in Shanghai covers 500 sq. meters and took three months to complete, constructed by E-Grow, a local company commissioned to provide the pavilion.

The futuristic design of the Egypt pavilion was created by the renowned modern architect, Zaha Hadid. E-Grow opted to make the more complex exterior and interior curved and rounded sections of the highly contemporary design in fire retardant GRP, made by hand lay–up using Scott Bader’s Crestapol 1212 resin and pigmented Crystic LS30PA ISO/NPG gelcoat. The materials were supplied by Scott Bader Asia Pacific from their Shanghai distribution operation, which serves China and other parts of Asia.

The pavilion interior is divided into two parts with a GRP arch through which visitors pass, and exhibited items include valuable antiquities, films and pictures showing Egypt's long history and rich culture. To ensure that the China Expo building fire regulations for all exterior and interior GRP parts were met to protect both visitors and the valuable artifacts, E–Grow specified the laminate construction in aluminium trihydrate (ATH) filled Crestapol 1212 high performance urethane acrylate resin, so that the same resin could be used throughout the construction.

Although the resin can be loaded up to 170phr of ATH to meet stringent fire, smoke and toxic interior test standards, only 100 phr of ATH filler was needed for the exterior GRP sections. The mechanical properties of Crestapol® 1212 have the added benefit of enabling lighter moulded parts with a thinner cross section to be produced, which helped reduce the overall costs of the pavilion structure and its assembly.
