Invista: Polyester product range expanded

Invista, one of the world's largest integrated polymers and fibers producers, announces the expansion of its "XPURE" portfolio of polyester products made with a next generation catalyst system.

Recent additions to this portfolio include the "XPURE" 7001 and 701K polyester copolymers. "XPURE" 7001 polyester is an amorphous resin while "XPURE" 701K polyester is a pre-cristallized resin. Both products offer a melting point of about 224°C which is about 30°C lower than a standard polyethyleneterephthalate. Application examples include packaging films and bicomponent fibers.

Invista´s "XPURE" polyester polymers are manufactured with a new generation catalyst system and offer easy flowing properties for better processability, as well as the possibility to use nonreactive thermal bonding methods.

"Initial customer testing of XPURE 7001 and 701K polyester polymers have been extremely well received", said Achim Heyer, business director Europe, polymers. "Customers reported a wider processing window vs standard polyesters, allowing to manufacture non-standard products such as thick transparent films. We hope that the expanded range will build a business growth platform for our valued customers."

Food contact approvals and confirmations are available upon request.
