accelerator ethylenethiourea (etu) was chemically grafted onto the surface of silane modified silica (m-silica) to obtain etu-modified silica (silica-s-etu). silica-s-etu could be homogeneously dispersed into the matrix of styrene-butadiene rubber (sbr) with fairly strong filler-rubber interaction and the grafted etu molecules were still able to accelerate the sulfur vulcanization.

vulcanization vulcanization
worker placing a tire in a mold before vulcanization. vulcanization (british english: vulcanisation) is a range of processes for hardening rubbers. [1] the term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. it has also grown to include the hardening of other (synthetic
select accelerators for rubbers specialchem,accelerator: an accelerator is a material that, when mixed with a catalyst and resin, speeds up the chemical reaction between the catalyst and the resin (usually in the polymerizing of resin or vulcanization of rubbers). accelerators are also known as promoters when used with polyester resins and vulcanizing agents when used with rubbers.
hot sell rubber accelerator etu (na-22),as the second accelerator, it has a little tendency to scorch, a high degree of processing safety and enables proper vulcanization to be attained speedily at normal vulcanizing temperatures. presents characteristics vulcanization kinetics and gives the vulcanization with excellent physical properties (high tensile strength, low compression set
- Which thiuram accelerator is best for vulcanization?
- ETU and thiurams: Thiuram accelerators, such as TMTD (Tetramethylthiuram Disulfide) and TMTM (Tetramethylthiuram Monosulfide), when combined with ETU, can enhance the vulcanization process and improve aging resistance.
- How to devulcanize natural rubber and styrene/butadiene rubber vulcanizates?
- Mechanochemical devulcanization of natural rubber (24) and styrene/butadiene rubber (25) vulcanizates was carried out using different concentrations of bis (3-triethoxysilylpropyl)tetrasulfide at ∼70 °C in an open-roll mixing mill.
- What is ETU & sulfur?
- ETU and sulfur: This combination is widely used in tire manufacturing and other rubber applications, providing excellent vulcanization properties, aging resistance, and overall performance.
- Why do vulcanizates increase tensile strength?
- This is due to the fact that with a greater proportion of silica loading, the vulcanizates become stiff and inhibit the stress transmission. The increase in tensile strength of NR/DeVulcNR/SiO 2 composites as compared to the NR/SiO 2 composites clearly indicates the reinforcement of silica filler in which DeVulcNR acts as an interfacial modifier.
