Product catalog summary

Introduction
Gurit specializes in developing and manufacturing structural core materials for sandwich constructions, enhancing stiffness and reducing weight. These materials are available in various forms to meet specific customer needs.

Core Materials Overview

Gurit® G-PET™ Thermoplastic Foam Core: A recyclable PET core offering a balance of mechanical properties, temperature resistance, density, and cost, suitable for diverse applications.
Gurit® PVC & PVC HT Cross-Linked PVC Foam: Closed-cell foams with high strength-to-weight ratios, chemical resistance, low water absorption, and excellent thermal insulation. The HT variant supports high-temperature processing up to 140°C.
Gurit® Corecell™ SAN Structural Foam: Known for toughness and impact resistance, ideal for large, high-performance structures.
Gurit® Balsaflex™ End Grain Balsa Wood Core: Offers a high strength-to-weight ratio, available in various densities and formats, and approved by Germanischer Lloyd.

Product Main Features
The document compares core materials based on shear strength, compression, dynamic impact resistance, fire resistance, processibility, and third-party certifications.

Applications and Certifications
Core materials are suited for marine, wind turbines, and civil structures, with certifications like GL, DNV, ABS, and RINA.

Product Formats
Gurit offers several product formats for different applications, including:

PL – Plain Sheet: Optimal material properties with limited bending.
PH – Plain with Bleeder Holes: Facilitates air release in vacuum bag processes.
SC – Single Cut: Flexibility in one direction, suitable for vacuum bagging.
DC – Double Cut: Flexibility in two directions, effective for resin infusion.
CS – Contour Scrim: Optimal flexibility, bonded to a glass scrim.
VIC – Vacuum Infusion Core: Customizable for specific grooving patterns and bleeder holes.

Applications
Gurit® Balsaflex™ is used in wind turbine blades, marine, automotive, and aerospace applications, offering a balance between cost, properties, and weight.

Technical Information
Detailed product information, including data sheets and case studies, is available on Gurit's website. Pricing and inquiries can be directed to their contact email.

Kitting Solutions
Gurit provides customized kitting solutions using CNC machining to create ready-to-use kits, minimizing waste and maximizing yield rates.

Sandwich Panel Engineering Theory
Sandwich structures enhance panel stiffness without significant weight. The core material acts as a separator, providing stability under various loading conditions. Failure modes like skin wrinkling, shear crimping, and panel buckling are linked to core material properties.

Structural Engineering with Core Materials
Gurit has extensive experience in engineering solutions for marine and wind energy applications, addressing challenges like pressure distribution and material selection to optimize performance and durability.

Conclusion
Gurit offers a comprehensive range of core materials tailored for different applications, ensuring high performance, durability, and compliance with industry standards.
