What materials is an NBA basket ball made of?

In June, 2006, the NBA announced that beginning this coming NBA season, a NEW BALL will be used. Here's the description and the site: http://www.nba.com/news/blackbox_060628.html

"The new ball features Spalding’s Cross Traxxion™ technology, a union of revolutionary design and breakthrough material. The design is comprised of two interlocking, cross-shaped panels rather than the eight oblong panels found on traditional basketballs. As a result, there is more material coverage. The material is a microfiber composite with moisture management that provides superior grip and feel throughout the course of a game. Additionally, the new composite material eliminates the need for a break-in period, which is necessary for the current leather ball, and achieves consistency from ball to ball. "
