Determination of vulcanization rate constant, crosslink density, and free sulfur content on carbon black flled EPDM

open access: yesMajalah Kulit, Karet, dan Plastik, 2017
Different ethylene propylene diene monomer (EPDM) composite with the carbon black (CB) variation of 50, 60, and 70 phr (per hundred rubbers) is compounded by using an efcient (EV), semi-efcient (SEV), and conventional (CV) sulfur vulcanization systems ...

Effect of vulcanization system and carbon black on mechanical and swelling properties of EPDM blends

open access: yesMajalah Kulit, Karet, dan Plastik, 2016
EPDM (Ethylene propylene diene monomer) is one of synthetic rubber that widely used in automotive. It must be vulcanized and added by other materials before used. The aim of this study is to investigate the effect of vulcanization system and the addition

Reversion free high-temperature vulcanization of cis-polybutadiene rubber with the accelerated-sulfur system

open access: yeseXPRESS Polymer Letters, 2020
The vulcanization of high diene elastomers with conventional or semi-efficient vulcanization systems exhibit reversion at a higher temperature due to the breakage of the polysulfidic crosslinks established in the vulcanized network.

Vulcanized vortex

open access: yesPhysical Review D, 2009
We investigate vortex configurations with the "vulcanization" term inspired by the renormalization of $ϕ_\star^4$ theory in the canonical $θ$-deformed noncommutativity. We focus on the classical limit of the theory described by a single parameter which is the ratio of the vulcanization and the noncommutativity parameters.
