Tailored Compounds for Safer, More Efficient, and Sustainable Tires
The tread compound is the most critical tire component for ensuring safety, reducing emissions, and enhancing performance. That’s why BD devotes significant research efforts to developing proven, ready-to-use solutions tailored to meet customers’ diverse needs and applications for tread compounds.
For PCR, we focus for example on low surface area fillers, advanced silica-silane coupling, low-Tg S-SBR grades, and modern raw materials like liquid polymers and resins.
For TBR, we specialize for example in high abrasion resistance compounds with balanced features and develop high silica-level compounds to improve rolling resistance (RR) and wet performance without sacrificing mileage. The most typical deliverables are:
- Compound recipe formulation
- Test result summaries
- Mixing recipe for lab/plant mixer
We offer hands-on support in material selection, compound formulation, and mixing technology for customers transitioning to renewable and recycled raw materials.
Comprehensive Compounding Support for Every Tire Application
Innovative Compounding Solutions
BD provides comprehensive support in developing and sourcing raw materials, integrating renewable and bio-based options into tire compounds. From the early stages of the supply chain to understanding the chemical interactions of materials, we focus on key areas to enhance both sustainability and tire performance:
