Performance Breakthrough! SBR Emerges as Hardcore Preferred Material for Passenger Car Tires & Industrial Hoses

On December 23, 2025, technical application notes released by Zhejiang Zhongrui Rubber revealed:

As a core synthetic rubber variety leading in both output and consumption, Styrene - Butadiene Rubber (SBR) - short for styrene-butadiene copolymer–has become indispensable for passenger car tire manufacturing and an ideal choice for industrial hose production. Its superior properties (wear resistance, heat resistance, anti-aging, etc.) provide critical material support for product upgrading and quality improvement in these two key sectors.

Hardcore Performance: Multiple Advantages for Dual Scenarios

Styrene-Butadiene Rubber (SBR) stands out with balanced and outstanding performance:

lClosely matches natural rubber in physical/mechanical properties, processing performance, and product service life.

lOutperforms natural rubber in four core indicators: wear resistance, heat resistance, anti-aging, and vulcanization rate.

lBoasts strong compatibility, enabling flexible blending with natural rubber and other synthetic rubbers.

lReduces R&D and production costs for manufacturers by offering diverse formula options.

Passenger Car Tires: Core Support for Safety and Durability

SBR is a "must-have raw material" for passenger car tire production due to:

lExcellent wear resistance: Extends tire service life under complex road conditions.

lStrong anti-aging ability: Maintains performance stability in extreme temperatures.

lReliable grip: Enhances driving safety on wet, slippery, or rough roads.

lActs as a key material guarantee for the high-quality development of the passenger car tire industry.

Industrial Hoses: A Reliable Choice for Complex Working Conditions

SBR excels in industrial hose applications with its:

lSuperior corrosion resistance: Resists erosion from chemical media in fluid transmission.

lHigh wear resistance: Reduces damage from frequent use and harsh environments.

lGood elasticity & recovery: Maintains structural integrity after long-term use and repeated bending.

lEnsures continuous industrial production by avoiding transmission failures caused by deformation.

Expanding Application Boundaries & Upgraded Industrial Value 

SBR’s application scope continues to grow rapidly:

lCovers basic sectors: Conveyor belts, wires/cables, auto parts (window seals, engine hoods), industrial seals, rubber adhesives, and coatings.

lExtends to high-end fields: Aerospace, construction, electronics, and medical care.

lFuture potential: With technological upgrades in automotive and industrial manufacturing, SBR will further meet high-end and customized material demands.

lCore value: Provides strong support for cost reduction, efficiency improvement, and quality upgrading in related industries.
