Invista, one of the world's largest integrated polymers and fibers producers has announced the expansion of its XPURE portfolio of polyester products made with catalyst system. Recent additions to this portfolio include the XPURE 7001 and 701K polyester copolymers. While XPURE 7001 polyester is an amorphous resin, XPURE 701K is a pre-crystallized resin. Both products offer a melting point of about 224°C which is about 30°C lower than a standard polyethylenetere phthalate. Application examples include packaging films and bicomponent fibers.
“Initial customer testing of XPURE 7001 and 701K polyester polymers have been extremely well received,” said Achim Heyer, Business Director, Europe, polymers, adding, “Customers reported a wider processing window versus standard polyesters, allowing to manufacture non-standard products such as thick transparent films.”
