The two-roll plasticizer (TRP)
The TRP Reworker is a resource saving technology for the economical processing of rework materials based on the two-roll plasticizer (TRP) with integrated Roll Ex gear pump. In an automatic process, unvulcanized rubber compounds are processed particularly gently and continuously in order to return this rework material to the production process. In tire production, compound waste is unavoidable due to the process.

Formlabs introduces Silicone 40A resin for 3D printing
Silicone 40A Resin combines the material properties of cast silicone with the flexibility of 3D printing to eliminate the labor-intensive molding and casting processes, while enabling design freedom. With this patent-pending Pure Silicone Technology™, users can print 100% silicone parts with complex geometries that are not possible with traditional methods — in-house, in a matter of hours. Silicone 40A Resin can be used for soft, pliable, and durable parts that can withstand repeated cycles of stretching, flexing, and compression, for functional prototyping and end-use part production. This material creates parts with excellent chemical and thermal resistance, perfect for automotive and industrial applications as well as consumer products such as wearables or medical devices.
