Rubber is a natural material and therefore has the properties of a “natural product”:
Temperature changes cause changes in size.
These are not permanent, and always regenerate.
Extent: about 0.2 % per 10°C (= about 2 mm per meter per 10°C )
Mechanical loads can cause lasting changes in length and width.
Here the rubber quality plays an important role.
Extent: with KRAIBURG there is a maximum of only 1%.
(Here KRAIBURG quality speaks for itself.)
extreme case: maximal change in size of a 1.83 m mat
remaining deformation: max. 1%
→ with a 1.83 m length: max. 1.8 cm
temperature dependent deformation: 0.2% temperature induced change for every 10°C
example: winter -10°C; summer 20°C = difference of 30°C (3 times 10° C)
→ with 1.83 cm mat length: 1.2 cm
Sum in this extreme case: 3 cm
⇒ distance to the cubicle rear edge: min. 3 cm!
