design strategy for vulcanization accelerator of- research
abstract. vulcanization is an essential process to obtain high-performance rubber products. diphenylguanidine (dpg) is often used as the secondary accelerator in the vulcanization process of natural rubber (nr) latex. however, dpg would make nr latex emulsion exhibit gelation, resulting in the negative vulcanization efficiency.
accelerator tdec high quality supplier,used for super accelerator in natural rubber, styrene-butadiene rubber. in general, using with some other kind of accelerators such as benzothiazole, sulfonamide. a fast velocity at vulcanizing temperature can be obtained, and intension can be increased.
on the various roles of 1,3-diphenyl guanidine in silica
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.
akrochem accelerator dpg cost,product description: accelerator dpg is useful as an accelerator/activator for natural rubber, sbr and nbr. it activates accelerators such as mbt, mbts and sulfenamides. it is a strong secondary for cbts, bbts, obts, mbt and mbts. dpg requires the use of zinc oxide and fatty acids.
effects of accelerators on the cure characteristics,this study demonstrates that the mbts/zmbt/dpg system is the most effective in enhancing tear strength by 4.5 % compared with mbts/dpg system, as well as other mechanical properties.
- What is accelerator DPG?
- Accelerator DPG is useful as an accelerator/activator for natural rubber, SBR and NBR. It activates accelerators such as MBT, MBTS and sulfenamides. It is a strong secondary for CBTS, BBTS, OBTS, MBT and MBTS. DPG requires the use of zinc oxide and fatty acids. DPG provides satisfactory processing safety and storage stability to rubber compounds.
- Why is DPG used in silica-reinforced rubber compounds?
- Further, while reacting with the silanol groups DPG reduces the polarity of silica by being adsorbed onto the silica surface [, , ]; and finally, DPG is also capable of accelerating the silanization reaction [2,4,7,8]. DPG therefore has turned into a multi-purpose compounding ingredient in silica-reinforced rubber compounds.
- What is DPG in chemistry?
- DPG is an organic compound belonging to the guanidine class of accelerators. It is a white to pale yellow powder with a faint odor. Chemically, it consists of diphenyl guanidine molecules. DPG is known for its solubility in rubber and compatibility with various types of rubber. 2. Characteristics of DPG:
