Absorbtion of of Mg and Pb

PH-sensitive Absorbent: Anionic Polyacryamide/Cassava Starch Hydrogels containing Natural Rubber for Lead and Magnesium removal from aqueous Solution

The novel absorbent from polyacrylamide (PAM), cassava starch and natural rubber (NR) by microwave assistance were produced to remove lead ion and magnesium ion in aqueous solution. The absorption of Mg2+ and Pb2+ of the novel absorbent increases as function of sample weight due to high site group or carboxylic group of absorbent. The highest […] more...

Terpolymer

Creating a Model for Novel Developments based on solubilty Parameters

HNBR is an elastomer with excellent heat and oil resistance, outstanding mechanical properties at elevated temperatures and good low temperature flexibility. Nevertheless, there is still a demand for further reduction in Tg while maintaining excellent media resistance. These modifications are not achievable with copolymers, which implies the application of terpolymers. While for many potential termonomers, […] more...

Anspruchsvolle Rezepturen erfordern eine hochentwickelte Mischtechnik

Das Tandemverfahren revolutioniert die Reifenindustrie

Die Anforderungen an Reifenmischungen steigen und ab 2020 soll der Kraftstoffverbrauch nochmals um 20 Prozent sinken. Dafür notwendig sind komplexe Kautschukrezepturen für Reifen, in denen wahrscheinlich flüssige Polymere, neue Füllstofftypen und sonstige Zusatzstoffe eine wichtige Rolle spielen. Schon jetzt hat das Tandemverfahren den Mischprozess erheblich verbessert. In Zukunft müssen die Maschinen bezüglich Dispersion, Distribution, Temperaturkontrolle und Prozesskonstanz bei verbesserter Wirtschaftlichkeit weiter optimiert werden. more...

EPDM blend for Profiles

Elaboration of Rubber Profiles for Automotive-industry

EPDM is extensively used in automotive applications and is favored to superior heat resistance, ozone resistance and weathering resistance. This study aims to elaborate rubber profiles for car windows and doors based on EPDM and EPDM/LLDPE blend formulations. Different prepared rubber compounds and vulcanizates were evaluated by determining the rheometric characteristics and physico-mechanical properties. The […] more...

Physical Properties of smart maleated Poly(vinyl alcohol) –g-Poly (N-isopropylacrylamide) and natural Rubber Latex

The objective of this work was to analyze the physical properties of smart polymer from a maleated poly (vinyl alcohol) (PVAM) graft copolymer with poly-N-isopropylacrylamide (PNIPAM) (PVAM-g-PNIPAM) and natural rubber (NR) latex in green route. The mechanical properties of  the swollen hydrogel was enhanced by the addition the NR latex.  The PVAM-g-PNIPAM and PVAM-g-PNIPAM/NR hydrogel […] more...

Oscillatory rheometer measurements

Characterization of Summer Tire Tread Compounds by Large Amplitude Oscillating Shear (Laos)

In the last years, characterisation of polymers by Fourier analysis of Large Amplitude Oscillating Shear (LAOS) signals became a powerful, widely spread technique. Oscillatory rheometer measurements were carried out in the non-linear viscoelastic domain for summer tire tread compounds based on the “green tire recipe”. Compound variations were realized by changing the polymer base well […] more...

German automotive industry to go on the offensive

VDA presents 10-point plan

Around 600 high-ranking guests from politics, business and academia attended the New Year Reception of the German Association of the Automotive Industry (VDA) in Berlin. The German automotive industry needs to have the policy-makers at its side if it is to maintain its competitive international position in the future. It is becoming more and more apparent that given these “disruptive times,” the companies are going on the offensive with a comprehensive strategy that can be summarized in ten points: By 2020 the manufacturers will more than treble their range of electric cars – from the current 30 to nearly 100 models. In 2019 electric drive will be present in practically all series, in the form of plug-in hybrids or purely battery-driven vehicles. Second, the German automotive industry will invest over 40 billion euros in alternative powertrains by 2020. In parallel to electric mobility, development of classical powertrains will continue. Reductions in consumption of 10 to 15 percent are possible. We need a reasonable trade-off between climate policy and industrial policy, a policy with moderation, and with a view to employment. more...
