the aim of this study was to evaluate the various roles of 1,3-diphenyl guanidine (dpg) in silica-reinforced rubber compounds. two roles of dpg are well known to be: adsorption onto silica surface to reduce the acidic sites and second to boost the silanization reaction as secondary accelerator. however, these two roles are in a way conflicting.
high-performance sulfur insoluble lanxess,nitrosamine-generating sulfur donors can be replaced by non-toxic caprolactam disulfide (cld, sulfur donor) or dithio-phosphates (e.g. sdt, sulfur donor plus accelerator) in all common sulfur-curable rubbers using standard, semi-ev (eficient vulcanization) and ev curing systems. all common primary and secondary accelerators, activators and

the lowest t 90 value (2.9 min) and the highest cri value (58.8 min −1) were observed for rubber compound cured with conventional curing system (accelerator/sulfur 1:2) based on tmtd accelerator, while the highest t 90 (16.1 min) and the lowest cri values (7.1 min −1) were observed for compound containing dpg accelerator.
robac zdec rubber accelerator robinson brothers,Used as primary or secondary super accelerator for natural rubber, isoprene rubber, butadiene rubber, nitrile rubber, high resilience rubber, EPDM rubber and their latex. Similar properties to PZ and EZ. Weaker accelerator for dry rubber than PZ and EZ.
effects of accelerators on the cure characteristics and supplier
the most used curing agent in the rubber industry is sulfur 1,2 , because it offers advantages such as low cost, good compatibility with other additives, and also the predictable properties of

rubber accelerator etu/na-22(ethylene thiourea) rubber accelerator: characteristics,etu (ethylene thiourea), also known as na-22, is a widely used rubber accelerator that plays a crucial role in the production of rubber products. this article aims to provide an overview of etu, its characteristics, its applications in rubber product manufacturing, potential product combinations, and important considerations for commercial procurement. 1. what is etu? etu is an organic
unveiling dpg rubber accelerator: features, applications, and supplier
2. characteristics of dpg: acceleration: dpg functions as a medium-fast primary accelerator, meaning it promotes the vulcanization process in rubber production. moderate reactivity: it offers a balanced level of reactivity, making it suitable for a wide range of rubber types, including natural rubber (nr), synthetic rubber, and blends.
performance characteristics of rubber additives and its,protective system additives. the rubber compound is prone to aging during use. it is necessary to add a protection system to delay aging and avoid rapid performance degradation. physical antioxidants are generally light shielding agents or waxes. chemical antioxidants include amines, phenols, esters and other compounds.
