INTRODUCTION

Gurit has established itself as a leading global supplier of composite materials, engineering, tooling, parts and

systems. Over 30 years’ experience in the practical application of composites across various market sectors,

combined with a unique technical approach enables Gurit to offer the complete composite solution.

Gurit’s range of fire retardant products are designed to deliver high performance laminates whilst meeting

demanding fire requirements. The ease of use and processing properties of these systems allow large parts to be

manufactured and the flexibility of either using the vacuum only consolidation, or press moulding.

The fire retardant range is available in a wide variety of formats from ambient curing liquid systems, to elevated

temperature curing SPRINT™ products. Typical applications include cladding of buildings, interior and exterior

aerospace and train parts, commercial / military craft and fire protection on external cosmetic detailing, roofing,

passenger ferries / superyachts.

SF 80FROBLFire Retardant Surfacing Film

¬ Provides an effective fire retarding layer to epoxy substrates

¬ With the correct tooling can provide a high gloss black surface finish

¬ Resistant to moisture ingress

INTRODUCTION

SF 80FROBL surfacing material is a Fire Retardant Obliterated Black (FROBL), filled epoxy film. It provides an effective fire retarding layer capable of withstanding exposure to fire, while preventing the epoxy substrate from combustion.

SF 80FROBL can be used directly against a suitably release treated mould surface, with prepreg or SPRINT™ plies laid up behind it, or as a final layer in the mould. The product is sufficiently tacky to aid placement into vertical surfaces of a mould. SF 80FROBL can be cured with vacuum only processing.

The epoxy system is supplied ready impregnated into a supporting medium and ready catalysed, requiring only a moderate temperature cure.


Typical applications include protection of structural components in high risk areas such as engine bays, exhaust runs, and around the fuel system.

G-PET™ FRFire Retardant Structural Core

¬ Excellent FST performance (Evaluated against DIN 5510, ASTM E1354, ASTM E662 & BSS7239)

¬ Withstands high process temperatures ¬ Excellent chemical resistance

¬ Good adhesion & mechanical properties ¬ Recyclable

¬ Compatible with all composite processes ¬ Available with G-PET™ LITE technology

INTRODUCTION

G-PET™ 75FR and G-PET™ 100FR have been developed in order to meet the growing need for structural core materials with good Fire, Smoke and Toxicity (FST) properties used in Marine, Civil and Transportation markets. It offers a much lower cost FST material compared to high cost / high performance materials such as PMI, PEI, PES foams, addressing lower requirements and needs.

Starting with G-PET™ which Gurit’s extruded structural PET core, flame retardant additives are added to improve FST properties. The manufacturing process remains the same as G-PET™, with slight variation in process settings. The material is available in all standard knife cut finishes as well as the new surface heat treatment technology G-PET™ LITE. G-PET™ FR is produced in Gurit Tianjin, China.
