Product benefits

According to EN 45545, in the event of a fire, the protection and safety of passengers and personnel should be awarded the highest priority. To ensure this, it is first and foremost necessary to prevent the spread of fire and the development of smoke gas which is hazardous to health.

Kaiflex railCLAD is a halogen-free elastomer composite with a very high insulation effect and smoke-restricting, fire-proof foil cladding. The insulation product provides active protection by expanding when exposed to heat, thus closing or shielding holes and preventing the fire from spreading to the next carriage or compartment. This also allows flammable substrates to meet the component inspection requirements of R1 HL3. The halogen- and heavy-metal-free materials prevent the development of toxic gases and dust particles in the event of a fire. This is particularly important in the case of railway vehicles that spend the majority of their travel time in underground sections with restricted evacuation conditions.

Kaiflex railCLAD also minimises energy losses and, thanks to its UV resistance, it is particularly suitable for exterior applications. The insulation product complies with all regional and national railway vehicle standards.

Product highlights

Piktogram, Snížení hluku

Effective sound insulation performance reduces noise pollution

Acoustic comfort improves the quality of life. Kaimann products have sound-absorbing properties that reduce the noise level of technical equipment and contribute to a quieter environment.

Piktogram, Oheň

High safety due to good fire behaviour

The requirements for certified safety in case of fire have increased worldwide for elastomeric insulation materials. Kaiflex reduces the spread of fire and smoke, is self-extinguishing and does not drip off when burning.

Piktogramm, UV

The outdoor solution

In outdoor applications, insulation is exposed to large temperature fluctuations, UV light , ozone and weathering. Kaiflex reliably withstands these influences.

Piktogram, Odolnost

Very good protection against damage

Mechanical influences can possibly deteriorate the performance of the insulation. Kaimann products are available with very robust jackets that protect the insulation from common causes of damage.

Piktogram, Tepelná účinnost

Excellent thermal values minimise energy losses

Inadequately insulated technical installations generate increased operational costs. Kaiflex has low thermal conductivity, which results in lower energy losses and increases the efficiency of the entire installation.
