What makes Levapren® so robust?


The superiority of Levapren® rubbers over "conventional" rubber materials results directly from its special chemical structure. Standard types of rubber contain a large number of reactive double binds which represent ideal points of attack for oxygen or ozone from the air, heat and UV radiation.


At a glance

  • Saturated molecular structure
  • No points of attack for ozone or UV light
  • Significantly slower degradation of property profile as a result of aging
  • Operational temperatures up to 175 °C


This means that conventional rubbers gradually degrade in any application where they are subjected to heat - the compression set increases, cracks and fractures appear under load, and the material eventually loses its elasticity.

The story for Levapren® is completely different. Unlike conventional rubbers, this polymer does not contain any sensitive double bonds. Its molecular structure stops the traditional "rubber killers" of heat, air and UV light from doing any damage.

Moreover, Levapren® rubbers offer the entire spectrum of valuable rubber characteristics thanks to the "integrated" insensitivity to operational temperatures up to 175 °C (to ASTM D2000/SAE J200).
