Its lasting high Young’s modulus at higher temperatures is one remark­able advantage of rayon as reinforcement for high performance mechanical rubber goods.  Copyrigth: all Cordenka

Prompt brake pressure generation contributes to automotive safety

Advanced Rayon Brake Hose Reinforcement

Cordenka rayon is a high tenacity man-made fiber based on cellulose extracted from wood. Its key property is a high Young’s modulus that is performed constantly in a temperature range between -40 and +120 °C. This feature as well as rayon’s low thermal shrinkage, its good resistance to chemicals and its sustainable raw material origin have made rayon popular as reinforcing material for automotive tires and brake hoses. more...

Erste Tests von Reifen mit dem naturidentischen, biomimetischen Synthesekautschuk Bisyka zeigen, dass diese etwa 30 bis 50 Prozent weniger Abrieb im Vergleich zu Naturkautschukreifen erzeugen. Bildquelle: Fraunhofer IAP, Till Budde

Biomimetischer Synthesekautschuk mit optimiertem Abriebverhalten

Synthetic rubber outperforms natural rubber

Natürlicher Kautschuk aus Kautschukbäumen ist ein begrenzter Rohstoff. Synthetisch hergestellter Kautschuk reicht bisher im Abriebverhalten jedoch nicht an das natürliche Produkt heran und eignet sich daher nicht für LKW-Reifen. Ein neuartiger Synthesekautschuk erzeugt nun erstmals 30 bis 50 Prozent weniger Abrieb als Naturkautschuk. more...

Ultra-high performance for demanding food and beverage applications

Sealing Compounds for coffee machines

Difficult technical requirements, sealing elements that need to withstand SIP & CIP processes, growing markets requiring industry & country specific approvals as well as a growing concern for health. These are just a couple of examples of the increasingly challenging environment that manufacturers of sealing solutions for the food & beverage industry have to face daily. And yes, standardization is also an important concern, so a solution fit for “everything” and approved for use “everywhere” has optimal market perspectives. The success of Angst+Pfister’s Pertec range in the coffee machines industry proves that such a solution actually exists. more...

Investigation of Tire Model Compounds

Optimizing the stress-strain behavior of hybrid yarns in elastomer components

Using a tire model compound, the bimodular stress-strain behavior of aramid/PA hybrid yarns in the range of 1-10% strain was adjusted by varying the process parameters during the hybrid yarn production, different yarn constructions, coating of the hybrid yarns and modifying the elastomer matrix by additives. more...
