What is n n diphenylguanidine (DPG)?

N,N’-Diphenylguanidine (DPG) is a vulcanization accelerator for natural and synthetic rubbers. Furthermore, N,N’-Diphenylguanidine (DPG) a secondary accelerator, activating Thiazoles (MBT, MBTS), Thiurams (TMTM, TMTD) or Sulfenamide (CBTS) in NR (0.1-0.5phr), SBR (0.15 – 0.75phr) and NBR (0.1-0,5phr) applications.

What are Yasho's rubber chemicals?

Yasho’s Rubber chemicals include Accelerators / Antioxidants / Co-agents for processing EPDM, SBR, NBR, ECO, Acrylic, NR and more. Specific examples are PIPERIDINIUM PENTAMETHYLENE DITHIOCARBAMATE (QUREACC®TBzTD) and TETRABENZYL THIURAM DISULFIDE (ZINC BENZENE SULFINATE DIHYDRATE) (QUREANTI®NDBC).

Which accelerator is best for rubber & latex?

And the sulfenamide accelerators are the most widely used and they have the best comprehensive performance. Fast, non-staining accelerator for both dry rubber and latex applications. Low temperature curing can be achieved when used with accelerator TMTD or accelerator DPG as secondary accelerators.

Is DPG poisonous?

DPG is grayish-white powder/granule. No taste, no poison. Density is 1.08-1.19.Soluble in acetone ethyl acetate, benzene, alcohol, slightly soluble in CCI4; Insoluble in water and gasoline. Used as a secondary accelerator with thiazoles and sulphenamides in NR and SBR compounds.

What is natural rubber used for?

In natural rubber it has a better anti-scorching quality and is generally safer in term of processing as compared to [DIBS]. Mainly used in manufacture of tyres, belts and shock absorber. Used in the production of both the SR and NR. Mainly used in the production of tyres, inner tube of tyres, shoes and cables.

What is SR rubber used for?

Used in the manufacture of both Synthetic Rubber (“SR”) and Natural Rubber (“NR”). Able to generate mild or moderate cure rate with high vulcanisation temperature. It operates safely, disperse easily and has low pollution level. It also carries an anti-oxidant function.
