INTRODUCTION
Gurit
Corecell M is the newest addition to the Gurit
Corecell range and shares the benefits of SAN chemistry common to all
Gurit
Corecell products.
Environmental stability – High tolerance for heat and chemical exposure
Built in toughness – High ductility and damage tolerance compared to cross-linked PVC and Balsa
Fine cell size – Resin absorption is very low, saving both weight and cost
Superior uniformity – Low density variation
Eliminating outgassing – Gurit
Corecell eliminates the problems of foam outgassing
Compatibility – Suitable for use with all polyester, vinylester and epoxy resins
No inhibition – Gurit
Corecell does not inhibit any epoxy resin curing mechanisms
Handling – Tough and easy to machine
Gurit
Corecell M has been developed to deliver one product for all Marine applications. It provides a combination of high shear
strength with low density, high elongation, high temperature resistance and low resin uptake. Gurit
Corecell M is the perfect
choice whether your application is slamming area or superstructure, hull or deck, using hand lamination, infusion or prepreg.
If looking for reliable processing, Gurit
Corecell M delivers through the benefits recognised in all Gurit
Corecell products of
fine cell size and unique knife-cuts giving low resin uptake in infusion processes. For prepreg, Gurit
Corecell M offers high
temperature resistance to allow shorter cure cycles and the confidence to process without fear of inhibition of prepreg catalysis.
Where static properties are important, Gurit
Corecell M delivers high shear strength at a low density. Where dynamic
performance is crucial, the high elongation delivers higher useful properties and the toughness to give impact resistance and
superior fatigue performance.
Gurit
Corecell M is available in resin infusion format and is compatible with polyester, vinylester and epoxy resin systems. The
low resin absorption characteristics of Gurit
Corecell and it s unique knife cut formats deliver higher performing infusions, low
resin cost and low weight. Gurit s global technical team have 10 years experience in resin infusion, hand lamination and prepreg
processing and offer on-site support and structural engineering for Gurit
Corecell customers. This combination makes Gurit
Corecell a key part of a reliable package.
