Additive manufacturing (AM) is a potential technology for future applications such as smart devices and airless tires. Natural rubber, which is used with restricted processing methods in the tire industry, has drawbacks for use in AM technology because of the high pressure and temperatures required to process it.

As a polymeric processing aid, it acts as a plasticizer of rubber compounds in the mixing and manufacturing process. Due to the presence of double bonds, VESTENAMER® takes part in the vulcanization process and is incorporated into the rubber matrix. Therefore, one can consider VESTENAMER as a reactive plasticizer. The properties of VESTENAMER®:
