Improving hysteresis of a typical carbon black-filled natural rubber tread compound by using a novel coupling agent

Abstract

Potential of Sumilink-200 was investigated in a typical natural rubber-based tread compound in connection with its ability to act as a coupling agent for carbon black to reduce hysteresis loss of the compound. Optimum physical properties were obtained at 2 phr loading of Sumilink-200. At this loading, tensile modulus at 300% elongation improved by 9.6% with a reduction in visco-elastic energy dissipation (loss tangent) at 60°C by 8.3% over the control compound. The abrasion resistance properties of the compounds found to remain unaffected with the introduction of Sumilink-200.

Tear fatigue behavior of lignin‐based sustainable rubber composites

“…But until now, due to its innate physico‐mechanical strength, NR is utilized in silica technology with the aid of silane coupling agent. [ 6 ] However, the incorporation of polar silica in non‐polar NR matrix is still a cumbersome task to perform. [ 6 ] To address this, epoxidation of NR emerged as an alternate of NR.…”

“…[ 6 ] However, the incorporation of polar silica in non‐polar NR matrix is still a cumbersome task to perform. [ 6 ] To address this, epoxidation of NR emerged as an alternate of NR. Due to the polarity of the epoxy group, epoxidized natural rubber (ENR) exhibits enhanced compatibility with polar moiety without muddling much of the inherent strength of NR.…”

Surface modification of MWCNT to improve the mechanical and thermal properties of natural rubber nanocomposites

“…[ 13,14 ] Therefore, it is necessary to improve CB dispersion in rubber matrices. Several techniques have been established to address this issue, including surface modification, [ 15 ] coupling agent addition, [ 16 ] functionalization of the polymer matrix, [ 13 ] and the addition of various nanofillers.

Impact of α‐cellulose as a green filler on physico‐mechanical properties of a solution grade styrene‐butadiene rubber based tire‐tread compound

“…CB, which is generated from fossil fuel, is extensively employed as a filler in rubber compounds due to its better molecular level interaction with rubbers. [2,[8][9][10][11] Nowadays, silica has become another suitable alternative choice of CBs in tire application as it provides better balance in magic triangle properties, namely rolling resistance, heat buildup, and wet grip. [9,12,13] As silica is derived from minerals and high energy is consumed during its production, so the cost of silica is higher than CBs.…”
