Viscoelastic Extrusion Processing Method and Compositions for Biopolymers

Номер: US20120013037A1
Принадлежит: Biovation LLC

A viscoelastic extrusion process (VEEP) for biopolymers such as polylactic acid is provided. The VEEP process removes many processing and performance limitations of PLA as well as creates performance sufficient to produce durable “nonbiodegradable” products as a direct replacement for PVC and other petrochemical profile and sheet extrusion applications. The VEEP process also retains a high degree of crystallinity within the PLA for increasing toughness and to lower its biodegradability. The invention also includes an integral process wherein rheology is highly modified to allow profile extrusion and higher melt strength wherein processing is lower than the melting point of the primary biopolymer and below the browning points of the natural fibers in the biopolymers viscoelastic state.

A high altitude balloon, including a method and machine for manufacture, uses a perimeter border strip to couple two circular balloon panels with a lap or butt seal. Simultaneous sealing of two perimeter seals, one between the border strip and each of two balloon panels, is provided by supporting stacked balloon panels on a rotatable support and sealing around the full perimeter of the two interposed balloon panels and the border strip. The method and machine for manufacture allow for the mass production of high altitude balloons and minimize necessary material handling. The perimeter border strip can be dispensed and guided relative to the perimeter of the balloon panels for positioning before sealing together, as a bonding device is rotated relative to the balloon envelope.
