Discover the special ingredients of our GEZOFLEX endurance EPDM granules
Synthetic rubber EPDM
Filler
The inorganic natural filler calcium carbonate (commonly known as chalk) affects among others the haptic experience of the finished EPDM granules and ensures optimal adhesion of the polyurethane binder and enhances the weight and volume properties of the granules. With regard to UV resistance, only calcium carbonate is used for GEZOFLEX endurance, which meets particularly strict specifications.

Color pigments and master batches
Well, with our GEZOFLEX, we are already the benchmark for color fastness and UV resistance in EPDM granules!
We could have rested on that! But we didn‘t!
We took up the challenge!
With GEZOFLEX endurance...
... we make good things even better!
... we are evolving the field of EPDM granules!
... we are setting completely new benchmarks!
A color stability that you have never seen before in EPDM granules!
GEZOFLEX endurance was developed with the goal of ensuring exceptionally high resistance to UV radiation. Based on the standard formulation of the proven GEZOFLEX EPDM rubber granule, every single raw material was scrutinized down to the last detail during the development process lasting several years. As the result, GEZOFLEX endurance not only uses outstanding UV stabilizers, but also carefully selected, high-quality additives with very tight specifications.
The result is an EPDM granule for sports and leisure flooring with exceptionally long-lasting color stability and unprecedented values on the gray scale! GEZOFLEX endurance far exceeds the value of ≥ 3 on the gray scale after the UVA exposure of 4,896 kJ - 2550 h required by the standard! But that‘s not all! Even with an exposure duration almost twice as long (9,600 kJ - 5000 h), GEZOFLEX endurance still easily fulfills the requirements beyond the level required by the standard!

GEZOFLEX endurance EPDM granules are part of the GEZOFLEX product family, serving as an addition to the existing GEZOFLEX standard colors. This specialized product line features six bright colors each designed to impress with their superior UV performance.
The colors of GEZOFLEX endurance can be limitless combined and mixed with any other colors from the entire GEZOFLEX product family. Let the sun inspire your creativity and create your own customized color blend, for example!
Like other EPDM granules for sport and leisure flooring, GEZOFLEX endurance can be processed with one- or two-component polyurethane binders or coating. Thanks to its enhanced stability against UV radiation, GEZOFLEX endurance is particularly suitable as a top layer for projects expected to face high levels of UV exposure.
GEZOFLEX endurance does not differ from conventional EPDM granules in terms of application diversity and processing options! It is just as variable and convenient to use as all other GEZOFLEX EPDM granules for all known application. Typical areas of applications include athletic tracks, multipurpose sports surfaces, fall protection flooring, prefabricated slabs and rolled goods for various flooring systems. GEZOFLEX endurance is perfectly suited for the following processing methods:
