Change crack phenomenon, improve tyres durable performance and high speed performance.Rare earth polybutadiene rubber is cis-content highest, object in butadiene rubber
Manage the best glue kind of mechanical performance.From the point of view of world development trends, rare earth polybutadiene rubber can substitute other butadiene rubbers, become
The important raw and processed materials of high-performance meridian tire is manufactured, development prospect is very wide.
Due to characteristics such as excellent resilience, low hysteresis loss and high abrasions, NdBR is low to high-performance high-quality to roll resistance
The exploitation of wheels tire becomes ever more important, becomes the development priority of tire new material.Narrow ditribution NdBR adds since it is preferable
Work performance and dynamic property become the emphasis of NdBR exploitations.
Tire sidewall position is deformed in tire operational process and hysteresis loss is all larger, to influence the service life of tire
And an important factor for rolling resistance.Current most of research, which only focuses on, improves fatigue performance, the heat on reduction sidewall, raising tire
One side in side heat conduction etc., and the overall performance for promoting ability tire of comprehensive performance extend the service life of tire,
Improve safety.
