Product description

Introducing KRAIBON® from our partner Gummiwerk KRAIBURG, a revolutionary material that is sure to transform the world of composites. KRAIBON® is a thin rubber elastomer that is co-cured with thermoset resins, resulting in a composite material, which combines the positive characteristics of fiber reinforced plastics and rubber elastomers. that is in a strong and flexible material that is perfect for multi-material bonding.

With KRAIBON®, you can achieve permanent flexible joints between composites, allowing you to create designs that were previously impossible. Whether you're working on automotive components, sporting goods, or medical and orthopedic applications, KRAIBON® is the perfect material for achieving the strength, durability, and flexibility that you need.

Thanks to its unique properties, KRAIBON® is an excellent choice for designers and engineers, who want to push the boundaries of what is possible. This innovative material is perfect for creating complex shapes and designs, and it can be used to create joints that are stronger and more flexible than ever before.

KRAIBON®Fire is a versatile material designed for high-performance fire protection and safety applications, particularly in railway applications where it meets the stringent EN 45545-2 HL3 R1 standard. This advanced material offers superior weather and oil resistance, as well as improved noise dampening properties for added comfort and safety. In addition, KRAIBON®Fire boasts exceptional energy absorption capabilities, making it ideal for impact protection applications. This material can be used both as a bulk material and surface ply, providing flexibility and versatility in various applications.
