What is ISO 23508 – Viscoelastic properties of solution-polymerized SBR about?
ISO 23508 is an International Standard that discusses solution polymerized solution-polymerized styrene-butadiene rubber (SBR).
ISO 23508 specifies the standard test formulation, mixing procedure and test methods for evaluation of viscoelastic properties in a compound based on solution-polymerized SBR, including functionalized S-SBR.
Who is ISO 23508 – Viscoelastic properties of solution-polymerized SBR for?
ISO 23508 on determining viscoelastic properties of solution polymerized SBR is useful for:
- The rubber manufacturing industry
- Tyre manufacturers
- The automotive industry
- Quality control and testing authorities
- Regulatory bodies
Why should you use ISO 23508 – Viscoelastic properties of solution-polymerized SBR?
A variety of solution-polymerized SBR have been developed and used for tires because they show excellent balance between rolling resistance and wet grip.
It is well known that functionalized solution-polymerized SBR can strongly react with fillers, resulting in better dispersion and contributing to the low rolling resistance tire. These phenomena can be explained by the viscoelastic properties.
In other words, in order to describe the performance of solution-polymerized SBR, it is necessary to evaluate viscoelastic properties.
Therefore, ISO 23508 specifies the model compound formulation, mixing procedure, sample preparation, test conditions, etc. for evaluating the viscoelastic properties of the S-SBR compound, that is useful to the rubber industries.
ISO 23508 can be particularly beneficial for quality control purposes.
