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 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.
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.
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 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.
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.
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.
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.
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 is a very fast primary or secondary accelerator used in IIR (extremely fast curing), NR, NBR, SBR and EPDM.
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 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.
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 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.
Non-blooming accelerator for EPDM cures; improves reversion resistance in NR. Secondary accelerator for thiazoles and sulfenamides.
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 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.
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.
