REACH and RoHS compliant; ISO 9001:2015 certified production; bio-based renewable grade.
Yes, ESBO acts as a plasticizer and softener in rubber formulations, improving flexibility, compression set behavior and low-temperature performance.
ESBO improves thermal stability, electrical insulation and flexibility of PVC cable compounds when used as a co-plasticizer.
ESBO enhances flexibility, prevents stiffening over time and improves resistance to extraction by water and cleaning agents.
Typically 5-15 phr depending on the application; our technical team can provide formulation guidance.
We supply ESBO grades tailored for PVC, rubber and coating applications, all from the same stable production line.
