...ntains a heat-activated catalyst that causes it to cure in the mold to form a conventional high-molecular weight polymer--in this case, PBT polyester. This one-component “CBT” resin is supplied by Cyclics Corp.,Schnectady/New York, based on patented technology originally developed by General Electric. Because of their low initial viscosity, CBT resins easily wet out nano-particle fillers. CBT is suited to impregnating continuous-fiber reinforcements, facilitating production of thermoplastic comp...

The cooperation between the two companies may be extended, depending on future progress. Cyclics Search for a Site Cyclics Corporation has officially begun the search for a suitable site for a second plant for the world-scale production of its cyclic butylene terephthalate (CBT). Although the search is concentrating primarily on North Americ...

Kunststoffe international, 2005-11-21, PBT Oligomers: Always in Good Form
...Turning CBT into PBT In the mid-eighties, an American research team from General Electrics (GE) discovered that depolymerisation of PBT transforms it into a mixture of oligomeric products with low melt viscosity. Now this technology is owned by Cyclics Corporation of Schenectady New York/USA, which was founded in 1999. In this patented process, oligomeric ring compounds are produced in the presence of catalysts: cyclic butylene terephthalate (CBT). This low-molecular weight product, designated C...

...ined on a permanent basis (Fig.4). The composite panels can also be used in many different applications in the transport sector. In the field of polymer systems, a new development was displayed in the form of an in-situ polymerising system. Cyclics presented Cyclics CBT – a matrix system based on commercial PBT which could take on particular importance for liquid impregnation processes, and resin infusion or resin injection processes. The particular attraction of this system is its low reaction ...

...BT melts upon heating to yield a product with a low, water-like viscosity (about 20 mPas), a characteristic that can be exploited in various fields of application. In the following, the focus is on compounds and masterbatches, since the supplier, Cyclics Europe GmbH, Filderstadt/Germany, sees significant potential for development because of the special material characteristics of CBT. During compounding, the primary objective is the most efficient possible processing of the materials as well as ...

... Up to now LCM processes have been restricted to thermoset matrix systems for only these had sufficiently low viscosities. New possibilities are emerging here due to novel thermoplastic matrix systems which polymerise in situ, for example CBT from Cyclics, Schwarzheide/Germany. The modified injection technology needed for this purpose is currently under development.

...esins. Because of their relatively high melt viscosity, thermoplastics have not been suitable for LCM techniques. This clear distinction is being softened by a new materials development, so-called in-situ polymerizing thermoplastic systems. Cyclics Corporation, Schenectady, NY, USA, for instance, offers CBT as an oligomeric butylene terephthalate. The oligomers are initially present in ring form. The rings are melted by heating, opened by a catalyst and the material is then polymerized to yield ...
