The synergistic role of platinum and silica as a way to increase the final residue pyrolized silicone was investigated explained, giving new interpretations. Conditions were first set study thermal degradation silicones in presence based on simplest silicone/silica/platinum formulation. Numerous parameters, e.g., content or surface modifications, varied track their influences residues. A thorough DSC study, together with SEM/EDX Pyrolysis/GC-MS analyses, led us propose three-stage process....

In the previous paper of this series, eight formulations were analyzed under their uncross-linked forms to relate liquid silicone rubber (LSR) chemical compositions material network topologies. Such topologies confirmed by swelling measurements and hardness evaluation on vulcanized samples. article, characterization cross-linked materials is further done using different mechanical final materials, including dynamic analysis, compression set, stress-strain behavior tear resistance. It was...

This study proposes a comprehensive on liquid silicone rubber (LSR) formulations to unravel which components (among functional polydimethylsiloxane polymers and modified silica fillers) improve the mechanical properties of final materials. In this first part, various industrial products have been deformulated using conventional chemical analyses. The content their surface chemistry were assessed by TGA. Architecture molar mass deduced from (29)Si NMR SEC in toluene, respectively. Relative...

Ionic liquids (ILs) are increasingly used in elastomer technology due to unique physico-chemical properties, which stable at the temperature of preparation and during processing rubber compounds. The latest IL application concept is supported ionic liquid-phase (SILP) materials, where an film immobilized on solid phase. main aim this work was studying influence surface supports, such as silica carbon black, vulcanization process, mechanical thermal behavior ethylene–propylene–diene (EPDM)...

Ionic liquids (ILs) are widely used in elastomer composites, primarily as vulcanization activators or accelerators, crosslinkers, conductive additives, dispersing agents of fillers. The aim this work was to study the efficiency ionic liquid immobilization on filler surfaces using different techniques thermal analysis and scanning electron microscopy (SEM). liquid, such 1-decyl 3-methylimidazolium bromide (DmiBr) grafted surface silica, calcium oxide, carbon black improve dispersion degree...

Task-specific ionic liquids (TSILs) are with structures and, consequently, properties and behaviors designed for particular applications. In this work, task-specific ILs alkylammonium or benzalkonium cations carboxyl groups in the form of lactate anions were used to promote homogeneous dispersion curatives elastomer matrix. The reaction TSILs zinc oxide, which acts as a vulcanization activator, was confirmed. This interaction improved solubility dispersibility oxide particles...

Abstract This paper is devoted to the characterization and processing of high molar mass vinyl‐bearing polysiloxanes in consistency silicone rubber (HCR) formulations. The masses five different polydimethylsiloxane gums, bearing vinyl groups at ends along their chains, were evaluated by size exclusion chromatography rheometry. 29 Si 1 H NMR spectroscopy allowed precise determination content distribution polymers. Typical HCRs formulated from these gums heat‐cured process materials that then...
