Correlation between molecular and spectroscopic Properties of Polymers
The Mooney viscosity (MV) of rubbers is known to be an important processing parameter in the rubber industry.Weiterlesen...
A Capillary Rheometer with continuous Feeding
A new approach (Contifeed) for the determination of rheological behavior is presented. Contifeed combines a small lab extruder with a single or dual barrel capillary rheometer.Weiterlesen...
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.Weiterlesen...
Innovation in the e-mobility of power-assisted bikes and electro-scooter
Askoll, italienischer Hersteller von elektrischen Zweirädern, verwendet thermoplastische Elastomere zur Vibrations- und Geräuschdämpfung am Akkuanschluss seiner Pedelecs und Elektroroller sowie zur wasserfesten Abdichtung des Akkugehäuses. Zu den wichtigsten Anforderungen gehört dabei die zuverlässige Haftung auf glasfaserverstärktem PBT trotz geringer Kontaktflächen.Weiterlesen...
TPE for Bipolar Plates
Aus neuen Thermoplast-basierten Kunststoff-Compounds lassen sich 0,5 mm dicke Bipolarplatten für Batterien fertigen. Diese sind um den Faktor 5 bis 10 dünner als bisherige Platten mit 3 bis 4 mm. Die Platten werden mit dem Rolle-zu-Rolle-Verfahren hergestellt. Dafür wurde der Prozess für die spezifischen Materialien angepasst. Besonders wichtig ist zudem die Wahl der richtigen Mischung für die leitfähigen Compounds.Weiterlesen...
Approach for additive Manufacturing of high-viscosity, curable Rubbers by AME Processing (Additive Manufacturing of Elastomers) – Rubber 3D
Additive Manufacturing of plastic or metal parts is state of the art. But in order to use different materials there is still a great need for development.Weiterlesen...
Oscillating Buckling Dynamometry (OBD) of textile reinforced Rubber Laminates
The dynamic response of reinforced rubber laminates is related to the viscoelastic properties of the constituent materials and to their distribution within the thickness in a quite complex manner.Weiterlesen...
Use of natural Oils as potential Additives in filled Rubber Compounds for antistatic Applications
The effect of natural oils (castor and jojoba oils) as alternative ingredient for NBR and NR vulcanizates has been evaluated. Only for comparison, DOP is used as a reference plasticizer.Weiterlesen...
New Compounding Concepts based on very high Molecular weight EPDM
The evaluation of a series of very high molecular weight EPDMs with varying Mooney viscosity (ML), oil content and ethylene content in compounds with 400, 500 and 600 phr loading enabled the optimum design of a unique, very high molecular weight EPDM (Keltan 13561C), which satisfies the special requirements for automotive EPDM body seals.Weiterlesen...
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.Weiterlesen...
