Enhancing Tire Performance: The Power of POLYVEST®
POLYVEST® is used as reactive plasticizer in tire formulations. Due to its rubber-based nature POLYVEST® exhibits a natural fit and excellent compatibility to the rubber matrix of tire tread formulations.
Key Benefits of POLYVEST® in Tire Applications
- Excellent compatibility with solid and recycled rubber
- Less migration loss
- Improvement in performance indicators
- Improved processing through reduced compound viscosity
- Excellent chemical resistance to acids and bases
POLYVEST® ST-E: Revolutionizing Tire Performance
POLYVEST® ST-E, is a silane-functionalized liquid polybutadiene designed to enhance tire formulations. The product acts as both, a reactive plasticizer and a surface modifier for silica particles, effectively reducing particle interactions and agglomerations.
POLYVEST® ST-E offers a perfect blend of liquid rubber advantages and silane functionality, ensuring excellent compatibility with rubber matrices in tire tread compounds. When combined with sulfur silanes like Si 69® or Si 266®, it significantly improves key performance metrics, including rolling resistance, wear resistance, and compound viscosity.
Benefits for Tire Applications:
- Improved rolling resistance and fuel efficiency
- Improved processability & extrudability, low die swell
- Enhanced wear resistance
- Less migration loss
- Excellent compatibility with (recycled) rubber and silica particles
POLYVEST® 130 S: Enhanced Safety for Tire Performance
POLYVEST® 130 S is a premium polymeric plasticizer designed for superior processing and performance. Its outstanding compatibility with various rubbers and process oils enables the effective replacement of traditional plasticizers while maintaining low compound viscosity.
As a reactive plasticizer, POLYVEST® 130 S chemically bonds during vulcanization, minimizing migration and bleeding of compounds.
Benefits for Tire Applications:
- Boosts winter performance of tires
- Improved abrasion resistance
- Reduced compound viscosity
- Less migration loss
- Co-vulcanized by sulfur crosslinking
- Not extractable by solvents
