APPLICATION:
1. Under high temperature, perform better than BPA in improving the tensile strength and elongation at break of FKM.
2. Improve the pervmanent compression set of compounding.
3. Safe scorching.
4. Non-toxic, stable, will no react when exposed to the atmosphere even after a long period exposure.
5. After application, it can keep rubber with original fresh color.
