Introduction

Gurit® Corecell™ T has been developed as a technological step-change from traditional PVC and balsa structural core. Gurit® Corecell™ T is an outstanding core material in every application where balsa or X-PVC is commonly used. High mechanical toughness and thermal stability give Gurit® Corecell™ T excellent fatigue characteristics. This reliability makes Gurit® Corecell™ T a natural replacement for cross-linked PVC or balsa in applications where a significant service life is required.

The high temperature stability of Gurit® Corecell™ T also means that it can be used in manufacturing processes to at least 120°C with short durations during a cure cycle to over 150°C / 300°F. This makes it ideal for use with conventional prepregs and in some liquid infusion processes where high resin exotherms can often be seen. Gurit® Corecell™ T is available in every resin infusion format and is compatible with polyester, vinylester and epoxy resin systems. Low resin absorption characteristics of Gurit® Corecell™ and unique knife cut formats allow for higher performing infusions, lower resin cost & lower weight than any other structural core.

Typical Applications

Ideal for applications where loads are less dynamic in nature, such as above the waterline on yachts, on wind turbines and in mass transport
