mixing conditions of nbr/pvc nanocomposites such as mixing temperature, rotor speed and mixing time are determining parameters in rheological, mechanical and morphological properties of the compound. three levels were chosen for each parameter using design expert software via box-behnken method. the nanocomposite samples were melt-mixed in brabender internal mixer. the effect of various mixing ...

Attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (TPE) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. In order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic m...

Resistance of antichemical clothing primarily depends on the type of material it is made from, in particular on the type of polymer used for coating the fabric carrier. This paper reports on systematic investigations on the influence of the cross-linking density of an elastomer and the composition of a cross-linked elastomer on its resistance to permeation of selected organic solvents. Tests of...

Tertiary amine-modified corn starches were converted to their basic or hydroxide form and combined with carboxylated butadiene-acrylonitrile copolymer and butadiene-styrene-sulfonic acid polymer to produce ionically bonded filler-elastomer composites. An increasing percentage of the elastomer fraction in the starch-elastomer composite is insolubilized as the starch-to-elastomer ratio increases....

Styrene-butadiene (SBR) and acrylonitrile-butadiene (NBR) rubber blends with tetramethyl thiuram disulfide (TMTD) monosulfide (TMTS) accelerators environmentally friendly plasticizers, obtained from PET recycling biobased resources (LA/PG/PET/EG/LA), were prepared. The mechanical properties of the products tested compared those commercial dioctyl terephthalate (DOTP). TMTS was prepared by simpl...
