FFU Synthetic Wood

FFU Synthetic Wood Technology

Pultrusion extrusion technique

FFU synthetic wood is manufactured using a pultrusion-extrusion technique. Continuous glass-fibre strands are soaked in special polyurethane and a composite of the materials is obtained by curing at a raised temperature.

The whole process is controlled by a drawing tool that draws the synthetic wood profile out of the curing tool.

High-quality ISO certified production

A uniformly high quality of ISO certified production with unvarying material properties is guaranteed. By virtue of the manufacturing process, the FFU synthetic wood blanks are pore-free and are cut to standard lengths of 12 m.

Greater certainty of material behaviour

FFU offers the customer far greater certainty of material behaviour in practical use when compared to natural wood. Significantly better technical characteristics also allow better optimisation of the rail section – a huge advantage, particularly in the area of railway bridges.
In the ballast bed the underside of the synthetic wood sleeper behaves just like a wooden sleeper – a significant benefit for switch systems in the ballast bed.

Very high chemical resistance

Due to its closed cell structure, FFU does not absorb any moisture.
It also exhibits very high chemical resistance to oils, lubricants and pollutants. When FFU synthetic wood is used, environmentally harmful impregnation, annoying odours and weathering processes are unknown and remain a thing of the past.
