Deovulc ATP-70

Deovulc ATP-70 is an amine-activated Dithiophosphate, absorbed on a silica carrier system. It is designed to enable a rapid cure of EPDM and diene rubber, and is generally applied in combination with additional accelerators like thiazoles or sulphenamides. The use of Deovulc ATP-70 leads to a high level of cross-linking density and consequently to vulcanizates with low compression sets and excellent heat ageing.

Deovulc OTOS-80

Deovulc OTOS-80 is a highly effective sulphenamide accelerator of dithiocarbamyl type as non-dusting soft granules. It is used for rubber compounds with high requirements on reversion stability, very good resistance against oxidation and low compression set due to formation of short sulphur cross-links. It has proven to be very effective for antivibration applications.

Dibenzothiazole Disulfide

Dibenzothiazole disulfide is mainly used in manufacture of tires, rubber tubes, rubber shoes, rubber cloth and other technical rubber goods. It works as plasticizer and delayed action activitor in polychloroprene.

Properties Suppliers
Dipentamethylenethiuram Hexasulfide

DPTT is an effective primary or secondary accelerator or sulfur donor for use in IIR, CSM, EPDM, NR, IR, SBR and CR. DPTT improves heat resistance and aging properties of vulcanizates. It is particularly suitable for light-colored stocks.

ETU – 80G

Polymer bound predispersed ETU – 80G is recommended where a more eco-friendly material, high productivity and better dispersion is required.The active ingredient ETU is used in the vulcanisation of polychloroprene rubber (CR), epichlorohydrines and EPDM. ETU is also an activator and secondary accelerator for all other diene rubbers.

Properties Suppliers
Ethylene Thiourea

Ethylene thiourea is used primarily as an accelerator for vulcanizing polychloroprene (neoprene) and polyacrylate rubbers and also used in the manufacture of ethylenebisdithiocarbamate pesticides, such as amobam, maneb, mancozeb, metiram, nabam, and zineb,electroplating baths, as an intermediate in antioxidant production, in dyes, pharmaceuticals, and synthetic resins.

MBT – 80G

Predispersed MBT – 80G is recommended where a more eco-friendly material, higher productivity and better dispersion is required.The active ingredient MBT is an all purpose accelerator for non-tyre applications. It is more scorchy than MBTS. Used alone, it gives an intermediate cure rate, flat curve and very good aging resistance vulcanisate. MBT is often used in combination with MBTS, guanidines, thiurams, dithiocarbomates, thioureas, dithiophosphates and sulphenamides to allow a wide range of cure behaviour even for the slow curing rubbers like IIR and EDPM.

MBTS – 80G

Predispersed MBTS – 80G is recommended where a more eco-friendly material, higher productivity and better dispersion is required.The active ingredient MBTS is an all purpose accelerator for non-tyre applications and is the first delayed action accelerator in history. Used by itself, MBTS gives good processing safety, intermediate cure rate, flat curve and very good aging resistant vulcanisate. MBTS is often used in conjunction with MBT, guanidines, thiurams,dithiocarbomates, thioureas, dithiophosphates and sulphenamides to allow a wide range of cure behaviour even for the slow curing rubbers like IIR and EDPM.
