VESTENAMER® - Additive for the rubber industry with unique properties

VESTENAMER® 8012

The trans-double-bond content of VESTENAMER® 8012 is nearly 80%, which results in high crystallinity of about 30%. The melting point is 54 °C, and the melt displays a honey-like consistency. VESTENAMER® 8012 is stabilized with sterically hindered phenolic antioxidants.
