microstructure of the PU memory-cell-foam

How did we get the back protector so safe and yet so comfortable? It’s all in the material.

The SLYTECH Engineering Department understood that the ultimate safety and comfort properties could have only been achieved in the development of a special PU memory-cell-foam. This memory foam’s internal microstructure with its extraordinary behaviour is the essence of SLYTECH’S 2nd SKIN protective and comfort characteristic.

Why is it so extraordinary? How does it work?

When cold, the protector is rigid. However, as you put it on and the PU memorycell- foam warms up by your body temperature, it becomes extremely fl exible and contours to your shape.

Besides the fact that the material contours to the shape of your body, something else amazing happens: the soft pliable material actually becomes the most effective shock absorber available in back protection.

When impact occurs, the PU memory-cell-foam acts as an outstanding progressive shock absorber and actually adapts itself intelligently to different forces and speeds. The shock absorption increases proportionally and the body is protected thoroughly at any impact level.

When pressure is slowly applied, the air inside the microstructure of the small bubbles is forced out of the micro-holes on the surface of the foam, you will find that if warm enough, it is extremely soft!

In contrast, when quick sharp pressure is applied (like a hammer blow), the force of contact traps the air within the material. The thickness, density, and most importantly the protective qualities of the padding are maintained.

In other words, the protector becomes rigid.

This diagram represents the force transmitted through the protector and those perceived by the spine in a lab test simulating a very high impact crash.

On the X axis the time that elapses after a significant impact (which happens at point 0). On the Y axis the perceived forces on the body in Kilo Newton.

Traditional Plastic Protectors – Red Line
After impact, the diagram shows that right around 4 milliseconds, the perceived forces on someone wearing the traditional plastic protector (red line) will skyrocket into seriously dangerous territory. These types of forces are the kind that can break bones.
The reason it takes about 4 MS for those forces to be perceived is because of the padding that’s between the subject and the plastic piece. Once the padding is completely compressed (after 4MS), then the plastic is the only protection, and because plastic is rigid and hard, it offers no absorption of the forces. That explains the dangerous forces perceived by the subject.

Slytech 2nd Skin PU Memory Cell Foam Protector — Green Line
The Slytech back protector on the other hand (green line), because its PU memorycell-foam structure, does not experience the same JOLT of forces. The memory cells absorb the forces smoothly and effectively dampen the forces so that they are less perceived by the subject, thereby avoiding more serious injury. Comfort, flexibility, and protection have finally been combined. Now during all riding conditions, the softness of Slytech 2nd Skin will allow the body to move and react free of constraints.

It’s always-on protection.
