Accelerators for tires and rubber products
an accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency.

select accelerators for rubbers rubber accelerator
elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. it is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). the most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
zdec masterbatch (dithiocarbamate accelerator harwick,mixland zdec masterbatch is a fast curing accelerator for nr, sbr, nbr, ir, iir, biir, epdm. it exceeds zdmc in accelerating effects and shows a slight tendency to premature vulcanization. it is also used as a secondary accelerator for all sulfur curable elastomers.

qureacc tdec is ultra fast accelerator widely used in the manufacturer of extruded epdm rubber sponge for automobile doors where partial rapid curing is desired before blowing of rubber. typical usage level in epdm sponge is 0.3 parts. higher levels give good compression set but blooming can occur.
safer rubber accelerators latex gloves chemicals,this aimed to substitute zdbc with a safer secondary accelerator. zno was used as an activator for sulphur vulcanisation to improve cross-link efficiency. however, a cure system with zno alone takes three times longer to cure latex compared to an accelerated system.
accelerator tdec
rubber accelerator tdec is an extremely effective dithiocarbamate accelerator for use with natural rubber, sbr, epdm, nbr and others. it is especially active as a butyl rubber accelerator. akrochem tdec is an oil treated powder and is approximately 96% active. applications: akrochem tdec powder can be used where rapid cure rates are required.
tdec rubber accelerator: characteristics, applications,acceleration properties: tdec acts as a highly effective accelerator, promoting the vulcanization process by facilitating the cross-linking of rubber molecules. fast curing speed: it offers rapid curing speed, reducing processing and molding times in rubber production.
accelerators o. sundström ab,tbztd is a fast curing primary or secondary accelerator in nr, sbr and nbr applications. it is safer to process, providing longer scorch times than tmtd. in the vulcanization of polychloroprene rubber, with n, n'-ethylene thiourea, tbztd may be used as a retarder.
- How many accelerators are used in rubber vulcanizates?
- r temperature and with greater efficiency. Over 150 different chemicals belonging to different classes of composition are known to function as acceler-ators for rubber vulcanizates of which around 50 accelerators are most commonly used by the Rubber Industry.There is a wide variety o
- What determines vulcanization rate?
- The accelerator determines the rate of vulcanization, whereas the accelerator to sulfur ratio dictates the efficiency of vulcanization and, in turn, the thermal stability of the resulting vulcanizate. Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur.
- Why are accelerators used in vulcanizing elastomers?
- Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. The selection of an accelerator will depend on the specific vulcanizing system and curing properties.
- Which elastomers can be vulcanized?
- Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur. As a result, several of the same accelerators that are used with sulfur vulcanization systems can be used with zinc oxide/neoprene systems. Because there are so many, accelerators are generally classified by chemical family.
