BÜFA®-Firestop Reinforcement, Core & Non-woven Materials

We offer a multitude of reinforcement, core and non-woven materials as part of the system solution for a wide range of fire safety requirements. Light weight, chemical inertness and good mechanical properties in the right direction are the most important factors when it comes to choosing reinforcement materials for various types of processing. Matching fibre reinforcement in the form of mats, fabrics/materials and combinations of the two in various densities are also available.

Combination:
For combination with the right resins, the glass fibres can be used as a powder mat, a cut mat, complex, direct or spray roving, roving fabric, an endless mat or fabric. Choose the right reinforcement material for your type of processing.

BÜFA®-Firestop Bonding Pastes

BÜFA®-Firestop-Liquid Mat is cobalt pre-accelerated, fibre-reinforced and filled with ATH. BÜFA®-Firestop-LIQUID MAT is characterised by its very good mechanical properties, in particular, with regard to impact resistance and elongation at break.

BÜFA®-Firestop-Liquid Mat is primarily used as a “liquid laminate” between the gelcoat and the glass mat. For moulded parts with sharp edges and complex geometry, it serves to smooth the contours. This is intended to ensure that, when constructing the laminate, the glass fibres are well positioned all over. This avoids the need to position the fibres and therefore the formation of cavities between the gelcoat and the laminate.

 

 

BÜFA®-Firestop Foam Resin

BÜFA®-Firestop Foam Resin is a complete solution for the lightweight engineering industry based on RTM. It meets the highest fire safety standard EN45545-2 (HL2) in combination with BÜFA®-Firestop GC S 285. BÜFA®-Accelerator “Foaming Agent” must be used as the blowing agent, together with a peroxide such as Curox M-303.
 
The benefits to you:

  • Lighter parts (up to 45% less weight)
  • Material saving
  • Heat and noise insulation
  • Flexible options for shaping and colouring
  • Adaptable fire resistance
  • Homogeneous foam formation
  • Good working properties
  • High surface quality

 

BÜFA®-FireFox System

The best choice of fire retardant system

BÜFA®-FireFox is the premium system for manufacturing fire safety fibre-reinforced composite components in closed-system processes (e.g. RTM,  infusion, injection processes). Individual components allow a multitude of possible combinations for very specific customer requirements.

 

Offers weight savings of up to 40% without any loss of performance

For maximum stability and much higher tensile strength and resistance to heat deformation

 

For fibre reinforced applications

High performance at all levels

Many years of expertise & customised solutions

Over 20 years of fire safety expertise on the part of BÜFA Composite Systems goes into the BÜFA®-FireFox System. BÜFA is the developer of all the chemical components. The BÜFA®-FireFox System offers customised solutions for closed-system processes with the technical support of our experts.

High-performance system with applications across industries

The BÜFA®-FireFox System brings together fire safety and mechanical performance. Customers in a wide range of industries already use this system: e.g. wind energy, boat building and shipbuilding, customers in rail vehicle construction and the building sector.

Lightest weight

One system component of BÜFA®-FireFox is BÜFA®-Foam Resin with integrated fire retardant for RTM applications. The advantages of unfilled lightweight systems are material savings and short cycle times. Hardly any reworking is required and low-emission, machine-controlled processing is possible. Product benefits such as noise damping and heat insulation also contribute to sustainability.

Outstanding mechanical properties & maximum fire safety

The BÜFA®-FireFox System is a guarantee of fire retardant composite components with outstanding mechanical properties with maximum stability and much higher tensile strength and resistance to heat deformation And of course, it meets the highest European and international fire safety standards, such as EN45545-2.

Saving lives with high-tech

Whether a component meets certain fire safety requirements or not depends on many factors. Layer thicknesses, composition and structure of the laminates, the nature and type of the paint – how the product behaves in a fire results from the complex interplay of all these components and cannot be simulated in a satisfactory way. A fire testing laboratory with powerful measuring devices is therefore required here – and the experience that BÜFA employees have gained over decades of practical testing.


The BÜFA Development department has, among other things, a cone calorimeter for measurements in accordance with ISO 5660, analyses of which provide extremely precise information about the material performance in other testing procedures. Machines for testing in accordance with German and international standards, such as DIN 5510, UIC 564-2, ISO 4589-2 (Limited Oxygen Index, LOI) and IMO 1006, round off the options – in turn just a small selection from the complete range of BÜFA tests for artificial resin products.

How fire retardant systems work

BÜFA®-Firestop – systematic fire protection

In all systems that use glass fibre reinforced plastics, BÜFA®-Firestop converts the GRP composite material into a flame-retardant material and the GRP casing into a fire barrier.

In other words: BÜFA®-Firestop protects itself. This extraordinary effect is achieved by:

1. Carbonisation

The integrated fire retardant is turned into polyphosphoric acid when it heats up. The carbonised surface acts as a protective layer.

2. Dehydration

Aluminium hydroxide is broken down into aluminium oxide and water at temperatures above 200 degrees Celsius. The water cools down the seat of the fire and dilutes the smoke gases that are created. Aluminium oxide forms a protective ceramic layer.

3. Intumescence

As the temperature increases, the surface of the component swells. As it does so, the surface releases a protective foam that contains carbon.

4. Impact in the gas phase

Through efficient suppression of the seat of a fire in the early gas phase, further spread of the fire is prevented.
 
The products of the BÜFA®-Firestop range, used individually or in combination, have qualities that come into their own in all conceivable areas of application. All BÜFA®-Firestop products are strictly tested according to German and international standards. They are easy and quick to process and make no special demands of the manufacturing process. BÜFA®-Fire Retardant Systems give GRP components the fire protection they need and thus deliver optimal safety. Innovative solutions for all applications!
