logotype

The range of rubber accelerators  we have are produced by leading producers of rubber chemicals. They combine state-of-the-art technology with world-class manufacturing.

 

Our range of products:

CBS
CBS is a primarily amine-based accelerator giving good scorch safety, a fast cure rate and good modulus development in a variety of general purpose polymers. It is the most active sulfenamide in EDPM.

DCBS
 Provides longer scorch time, longer cure time and lower modulus than CBS, TBBS and MBS. Thus will require higher use levels for equivalent physicals; more often used in steel skim compounds for improved adhesion.

DPG
Used as a secondary accelerator with thiazoles and sulfenamides in NR and SBR compounds. Exhibits better storage stability compared to thiuram and dithiocarbamates but is not as active. DPG can be used in latex as a secondary gelling agent (foam stabilizer) in the silico-flouride foam process.

DPTT
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.

MBS
MBS provides extended scorch safety and good green stock storage stability compared to CBS or TBBS. It is recommended for applications where extended scorch safety is required such as thick extrusions, stocks with high loading or furnace blacks such as ISAF or SAF. Its long scorch delay is also advantageous in injection or transfer moulding operations.

MBT
Fast, non-staining accelerator for both dry rubber and latex applications. Low temperature curing can be achieved by the use of TMTD, TETD or DPG as secondary accelerators. MBT confers excellent ageing characteristics to vulcanizates.

MBTS
Gives flat, moderately fast cures in natural and synthetic rubber. Also used in a wide range of general purpose rubbers. Non-staining/non-discolouring in "white" stocks; acts as a plasticizer/retarder in polychloroprene rubber. Secondary acceleration is usually required for synthetic polymers. Exhibits better scorch safety than MBT.

NDBC
NDBC is an effective antiozonant for dynamic applications. It is used where a wax film would offer insufficient protection. It is used for IIR, SBR, NBR, CR and CO. Furthermore, it is used in EPDM and CSM for high heat resistance. It improves the UV resistance of colored CR articles. It can also be used as an antioxidant in CR, CSM, CO, ECO and EPDM.

TBBS
Provides fast cure and high modulus development in NR, SBR, BR and blends. Normally used alone or with small quantities of ultra accelerators in tire compounds or industrial rubber products. Can be used to effectively replace MBTS/DPG systems. TBBS may give equal modulus to CBS or MBS when used at a 10% lower level.

TBSI
A primary amine-derived accelerator that provides the long scorch and slow cure rate associated with secondary amine-based sulfenamides. TBSI offers advantages in improved reversion resistance, steel cord adhesion and storage stability. Alternative for MBS where the presence of nitrosamines is of concern.

TBZTD
TBzTD was developed to replace thiurams such as TMTD where the presence of nitrosamines is of concern. The dibenzylnitrosamine is not carcinogenic according to published literature. 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.

TDEC
TDEC is a very fast primary or secondary accelerator used in IIR (extremely fast curing), NR, NBR, SBR and EPDM.

TETD
TETD closely resembles TMTD in its applications. However, it is less scorchy. Due to its low melting point, excellent dispersion in soft compounds can be achieved. TETD is used as a peptizing agent in sulfur-modified polychloroprenes.

TMTD
TMTD can be used as a single accelerator, as a secondary accelerator or as a sulfur donor in most sulfur-cured elastomers. TMTD is scorchy and gives fast cure rates. In sulfurless and EV cure systems TMTD produces an excellent vulcanization plateau with good heat aging and compression set resistance. Good color retention is obtained in non-black vulcanizates. TMTD is a valuable secondary accelerator for EPDM. In the vulcanization of polychloroprene rubber with N,N'-ethylene thiourea, TMTD may be used as a retarder.

TMTM
Generally used as a secondary accelerator or as a booster for sulfenamides to achieve faster cure rates. TMTM is distinguished by very good processing safety in comparison with other thiurams, high curing activity and no discoloration. Unlike the thiuram disulfides, TMTM will not produce cures in the absence of added elemental sulfur. It is an excellent accelerator for polychloroprene in association with DPG and sulfur.

ZBEC
ZBEC is a primary or secondary accelerator for NR, SBR, IIR, EPDM and for natural and synthetic latices. ZBEC has the best scorch resistance of the whole range of zinc dithiocarbamate accelerators and offers excellent prevulcanization resistance in latex compounds.

ZBPD
Non-blooming accelerator for EPDM cures; improves reversion resistance in NR. Secondary accelerator for thiazoles and sulfenamides.

ZDBC
ZDBC is a primary or secondary accelerator in NR, SBR, IIR or EPDM. ZDBC is used in both natural and synthetic latices for faster curing than with ZDEC or ZDMC. Furthermore, it is an antioxidant in rubber-based adhesive systems.

ZDEC
ZDEC is a fast curing primary or secondary accelerator for NR, SBR, IIR, EPDM. ZDEC is used in both natural and synthetic latices. Furthermore it is an antioxidant in adhesive systems.

ZDMC
ZDMC is a fast curing primary or secondary accelerator for NR, SBR, IIR, EPDM. ZDMC is used in both natural and synthetic latices.

ZMBT
ZMBT finds its main application in latex where it is used as a primary accelerator in combination with ZDMC or ZDEC. Latex films cured with ZMBT have a markedly higher modulus. Furthermore a better compression set resistance in latex foam can be achieved, without increasing the cure time. ZMBT does not destabilize latex formulations. In dry rubber applications, the performance of ZMBT is almost similar to MBT with slight scorch improvement.
