VESTENAMER® is a high performance component for rubber formulations. It is a reactive plastiziser and compatibilizer for elastomers of different polarity. It improves the melt flow reducing cycle times in injection or compression molding and also improves the mechanical properties of the final part, including excellent surface quality of complex parts. In many cases, the special capabilities of VESTENAMER® make it possible to successfully combine materials that are typically incompatible.

Key features

• Reactive plasticizer
• Compatibilizer between elastomers of different polarity
• Increased flowability (improved injection and compression molding)
• Increased throughput
• Reduced die swell
• High green strength and dimensional stability
• Excellent surface finish
• Increased abrasion resistance
• Lower reversion of natural rubbers

VESTENAMER® can be used in medical equipment applications, such as rubber seals and stoppers. It is supplied as cylindrical pellets in polyethylene packaging.
