Product benefits

Kaiflex railPROTECT is used wherever a high hazard level is present. For instance, this applies to plastic water tanks in sleepers or railway vehicles used in tunnel traffic.

The potentially flammable materials which lie under the insulation are afforded passive protection by the film cladding, which also prevents the development of smoke. The visually sophisticated silver surface cladding is also notable for its low emission ratio and protects the insulation against mechanical loads and damage.

Product highlights

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.

Pictogram, Fire

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.

Piktogram, Koroze

Safe corrosion protection

If the temperature of the surface is below the ambient temperature, condensation will form. Kaiflex prevents the formation of corrosion under the insulation thanks to its closed-cell properties.

Piktogram, 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, Halogen

Guaranteed halogen-free

Kaiflex is free of PVC, chlorides and brominated flame retardants, making it the ideal choice for construction projects with high safety requirements.
