Sanitized has introduced a new product from its BroadTect portfolio. The additive is said to protect polmyers against all relevant microorganisms (grampositive and gram-negative bacteria, mold and mildew, yeasts, and even algae. It has high temperature resistance and features durable antimicrobial protection that is effective even after weathering. In addition, good antiviral efficacy on surfaces has been demonstrated. The additive product is suitable for most thermoplastic polymers such as PE, PP, TPU, EVA, PVC, rubber (EPDM, NBR, SBR) that are used in the extrusion or injection molding processes. It is compatible with commonly used additives.

Managing end-of-life tyres remains both a technological challenge and a burden for society as the durability of tyres which makes them so invaluable to modern society hinders their recyclability. As compared to traditional methods of tyre disposal like incineration, the circular use of tyre rubber can reduce the environmental impact of these materials. This study investigates the effect of addition of waterjet rubber powder on the processing and the properties of a sample recipe of tread compound for a passenger car tyre. The findings indicate that recycled material can be successfully incorporated within new rubber compound without compromise of the mechanical properties.
