KRAIBON® - THE PERFECT SUPPLEMENT FOR YOUR COMPOSITES
With more than 70 years of experience in the productions of high-quality technical rubber and silicone compounds, Gummiwerk KRAIBURG also focuses on the dynamically growing composites market.
For this purpose, a product family has been developed that introduces special properties into fibre-reinforced plastic (FRP) and hybrid laminates.
What is KRAIBON®?
KRAIBON® is integrated directly into the layer structure in the manufacturing process which is typical of fibre composite. No additional bonding agents are required since this property is introduced directly in the formulas. KRAIBON® has inherent adhesiveness (tack) and, after warming, can easily be draped.
The elastomer cures under the same manufacturing conditions as thermosetting resin systems and forms a permanently stable chemical bond with the matrix. No additional processing steps are required. The result is an alternately hard and soft composite material which combines the positive properties of fibre-reinforced plastics and elastomers.
Areas of application
The KRAIBON® products are designed for use in fibre composite and hybrid components. The focus here is on acoustics, splinter protection, energy absorption and the constructive combination of various material classes.

For multi-material bonds in composite industry
KRAIBON® Hybrid bonds chemically to fibre-prepregs as well as to a wide range of materials such as steel, aluminium or even natural fibres, carbon fibres as well as fibreglass. It offers a permanent bond – comparable with structural adhesives – while at the same time offering improved acoustics, impact and splinter protection, and thermal and electrochemical decoupling of the material partners.
Properties of KRAIBON® Hybrid
- High energy absorption
- Long and reliable service life
- Easy to cut to any desired size
- Outstanding stability to weight ratio
- Bonding with and between a wide range of materials
- Equalization of the thermal expansion of various materials
Benefits of KRAIBON® Hybrid
Weather and ozone-resistant
High energy absorption
Temperature-resistant to approx. 170°C
Multi-material adhesion

Damping solutions for the composite sector
KRAIBON® Damp works according to the principle of “Constrained Layer Damping (CLD)”:
the viscoelastic elastomer layers absorb structure-borne noise vibrations and damp them, up to complete noise cancellation. The highly damping material, which has its optimum effect at temperatures of between approx. +15 °C and +40 °C, reliably improves the acoustic behaviour of composite components.
Properties of KRAIBON® Damp
- Passive structure-borne noise insulation
- Long and reliable service life
- Easy handling and direct integration
- Outstanding stability to weight ratio
- Very high damping across a wide range of temperatures and frequencies

Impact and splinter protection for the composite sector
KRAIBON® Impact binds sharp-edged fibre fragments resulting from impacts and breakages and reduces their dispersion and number. The risk to nearby persons or components is thus mitigated. To this end, the failure pattern of the component is ductile, similar to metal, and there is no sudden failure. Thanks to the “slow yielding”, residual function is retained during the beginning of the breakage and even after complete failure of the fibre composite laminates.
Properties of KRAIBON® Impact
- Easy to drape
- Low grammage
- High energy absorption
- Different stiffnesses possible
- High friction when used as an outer layer
Benefits of KRAIBON® Impact
Weather-resistant
High energy absorption
Impact protection
Flexible
Lightweight construction
High-temperature applications for the composite sector
KRAIBON® Temp is developed and optimized for use in applications with very high temperature loads. In addition to permanent stability up to +280 °C, the material is designed for contact with aggressive media (oils, petrol, acids, bases etc.). It can therefore also be used as an outer protective layer for fibre laminates.
Properties of KRAIBON® Temp
- Structure-borne noise insulation
- Permanently flexible bond
- Absorption of thermal expansion
- Suitable for high-temperature applications
- Comprehensive media-resistance across a broad range of temperatures
Benefits of KRAIBON® Temp
Weather-resistant
Temperature-resistant +280 °C
Impact protection
Flexible

Fire protection for the composite sector
KRAIBON® Fire is optimized for use in applications which need to meet particularly high fire protection requirements. The composite meets the requirements of the highest fire protection class in the rail sector: EN 45545-2 HL3 R1. KRAIBON® Fire is weather and oil-resistant and can be used both within the layer structure and as an external coating.
Properties of KRAIBON® Fire
- Improvement of the component acoustics
- High energy absorption in the event of impact
- Can be used as an internal and external layer
- Reliable protection of the underlying layers
- Suitable for fire protection in accordance with EN 45545-2 HL3 R1
- Adhesion to all common thermosetting resin systems
