With the global promotion of carbon neutrality policies and the rapid growth of the new energy vehicle industry, green tire standards have become increasingly stringent. Traditional ESBR and ordinary non-functionalized SSBR can no longer meet the dual requirements of low energy consumption and high driving safety for electric vehicles.
Functionalized SSBR is modified with special chain-end functionalization technology, which significantly improves the bonding force between rubber molecules and silica fillers. Compared with conventional rubber materials, it effectively reduces tire rolling resistance, lowers vehicle power consumption, and improves wet-skid braking performance, solving the performance trade-off dilemma of traditional tire rubber.
In the EV tire industry, lightweight, low heat generation, and low rolling resistance are core indicators. Functionalized SSBR perfectly adapts to high-content silica formulas, delivering outstanding wear resistance and aging stability. It has become the preferred material for major international tire manufacturers to produce high-performance green tires and electric vehicle-specific tires.
As global environmental regulations continue to tighten and the new energy vehicle market expands continuously, the market demand for high-performance functionalized SSBR will maintain steady growth, gradually replacing ordinary SBR grades and becoming the mainstream development trend of the global rubber raw material industry.
