Examples of solution polymerized styrene-butadiene rubber grade rules are as follows:

1. Plasticizer model: such as S-SBR1500, S-SBR1705, etc. The numbers indicate the plasticizer model, representing different molecular structures and properties. Generally speaking, lower numerical plasticizer models generally have higher abrasion resistance, while higher numerical plasticizer models have better wet grip.

2. Hardness and performance level: For example, S-SBR70HR. The number here indicates hardness, and HR is the unit of hardness. The hardness of S-SBR usually ranges from 60 to 80, with higher hardness representing higher stiffness and elastic modulus.

3. Functionality: Some brand rules also include descriptions of specific properties or functions. For example, S-SBRX-BR is an S-SBR obtained by changing the reaction conditions during the polymerization process, and has better mechanical properties and wear resistance.
