Window seals virtually unaffected by the elements after 22 years of service

The test confirms that the original UOB profiles are remarkably similar to the new Santoprene TPV profiles — even after 22 years of exposure to the elements.

In 1996, the UOB Plaza Tower, a landmark building in Singapore, was fitted with window seals made with Santoprene TPV. 22 years later, following a major retrofit, these were replaced. It was the perfect opportunity for ExxonMobil to examine the old seals and compare them with new profiles.
