Styrene Butadiene Rubber: Uses, Types, and Buying Tips from China


Styrene Butadiene Rubber (SBR) is a synthetic rubber widely used in industries like automotive, construction, and footwear. Known for its durability and cost-effectiveness, SBR is a preferred material for manufacturers worldwide. This guide covers everything you need to know about SBR, from its types to sourcing strategies.


How to Find Reliable Styrene Butadiene Rubber from China in 2025


China remains a top supplier of Styrene Butadiene Rubber, offering competitive pricing and high-quality products. To find reliable suppliers:

  • Check certifications like ISO 9001 and REACH compliance.
  • Verify supplier reviews on platforms like Alibaba.
  • Request samples to test quality before bulk orders.

What Buyers Should Know Before Buying Styrene Butadiene Rubber from China


Before purchasing, consider:

  • Mooney viscosity: Affects processing ease.
  • Oil extension: Determines flexibility and cost.
  • Lead times and logistics for smooth delivery.

Types of Styrene Butadiene Rubber


SBR comes in two main types:

  1. Emulsion SBR (E-SBR): Used in tires and footwear.
  2. Solution SBR (S-SBR): Offers better wear resistance for high-performance tires.

Functions and Features of Styrene Butadiene Rubber


SBR is valued for:

  • High abrasion resistance.
  • Good tensile strength.
  • Cost-efficiency compared to natural rubber.

Scenarios of Styrene Butadiene Rubber


Common applications include:

  • Tire manufacturing (70% of global SBR demand).
  • Footwear soles and conveyor belts.
  • Adhesives and sealants.

How to Choose Styrene Butadiene Rubber


Select SBR based on:

  • Application requirements (e.g., heat resistance for tires).
  • Supplier reputation and after-sales support.
  • Budget constraints (E-SBR is cheaper than S-SBR).
