LANXESS
has officially launched two new easy-to-process neodymium-based cis-butadiene rubber products, Buna Nd 22 EZ and Buna Nd 24 EZ, to further simplify the production of
fuel-efficient tires and other products.
Both new products are currently available for samples or for industrial series production
.
In recent years, energy saving while taking into account other performance has been one of
the main problems facing the tire industry.
High-performance tyres reduce fuel consumption and CO2 emissions
.
In general, the higher the molecular weight of rubber, the lower
the rolling resistance of the tire.
One of the key features of the two new products from LANXESS is their narrow molecular weight distribution and outstanding high molecular weight
.
Compared with other high-performance cis-butadiene rubbers with a wide molecular weight distribution, high-molecular-weight neodymium-based cis-butadiene rubber is superior in key properties, such as lower rolling resistance and better
wear resistance.
High molecular weight means high Mooney viscosity, so the processability of the product is also a key issue
.
It is worth noting that the Buna Nd 22 EZ and Buna Nd 24 EZ are extremely easy to process due to
the latest rubber modification technology from LANXESS.
Patented long-chain branching chemical modification enhances rubber-filler interaction and accelerates the rapid and reliable integration of rubber and filler to improve processing
.
At the same time, the modification also enhances the phase distribution between the polymers, so that the dispersion of the filler in the final refining compound is also improved, so that the adhesion of the rubber during the production process can be greatly improved
without any auxiliary processing.
"All in all, they offer similar performance to their predecessors and are easier to process, making them ideal for
use in addition to the high-performance Buna CB22 and Buna CB24 neodymium-based cis-butadiene rubbers that are already widely used in the tire industry.
Dr.
Ge Rubai, head of LANXESS's high-performance cis-butadiene rubber business unit, said
