Rubber Accelerators

Product Name:

Model:

Description:

TMTD can be used as a single accelerator, as a secondary accelerator or as a sulfur donor in most sulfur-cured elastomers. TMTD is scorch and gives fast cure rates. In sulfur less and EV cure system TMTD produces an excellent vulcanization plateau with good heat aging and compression set resistance. Good color retention is obtaining 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.

Product Name:

Rubber Accelerator TMTM

Model:

NURCHEM TMTM

Description:

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 dissulfides. TMTM will not produce cures in the absence of added elemental sulfur. It is an excellent accelerator for polychloroprene in association with DPG and sulpur.

Product Name:

Rubber Accelerator TiBTD

Model:

NURCHEM TiBTD

Description:

Super accelerator and vulcanizing agent for NR.IR.BR.SBR.NBR and EPDM. Generates low level of relatively non-toxic nitrosamine, effective in latex as well as dry rubber. Cure ability is good but the streuth is poor. Cure acitivity is good in the absence of sulphur

Product Name:

Rubber Accelerator MBTS

Model:

NURCHEM MBTS

Description:

MBTS, gives flat, moderately fast cures in nature and synthetic rubber. Also used in a wide range of general purpose rubbers. Non-staining/non-discoloring in “white” stock; act as a plasticizer/retarder in polychloroprene rubber. Secondary acceleration is usually required for synthetic polymers. Exhibits better scorch safety than MBT.

Product Name:

Rubber Accelerator DPG (D)

Model:

NURCHEM DPG

Description:

DPG, may be used as a secondary accelerator with thiiazoles 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 silicon-fluoride foam process.

Product Name:

Rubber Accelerator DOTG

Model:

NURCHEM DOTG

Description:

Suitable for NR, SNR, IIR, IR, SBR, NBR and CR. Seldom uses alone, commonly with thiazoles, thiurams, dithiocarbamates and sulphenamides to promote its activity, This product is a plastic-decomposing agent in CR. However, this product is not suitable for food-related products or medical products.

Product Name:

Rubber Acceleartor DCBS (DZ)

Model:

NURCHEM DCBS

Description:

Provide a longer scorch time, longer cure time and lower modulus than CZ TBBS and MBS. Thus will require higher use level for equivalent physical properties; more often used in steel skim compounds for improved and adhesion

Product Name:

Rubber Accelerator ZBEC

Model:

NURCHEM ZBEC

Description:

A overspead accelerator for natural and synthetic rubber and latex. Curing active temperature is low. It can substitute for ZDBC 、ZDEC 、PZ, etc.. Operating safety is much better. Specially, it will not produce cancer-causing nitrosamize during the rubber manufacturing process and it can be used as excellent activator to kinds of thiazoles. Appropriate matching quantity of Zinc oxide and sulfur when using, and aliphatic acid is not necessary .it can be added directly into rubber mass and also can be added into latex as component part.

Product Name:

Rubber Accelerator ZDTP

Model:

NURCHEM ZDTP

Description:

ZDTP is a fast curing secondary accelerator for NR and EPDM. It is mainly used as an accelerator in non-blooming., relative low cost, fast curing systems for EPDM when used in combination with MBTS or sulfenamides in NR compounds. ZDTP dramatically improves reversion resistance. Because of its non-amine based structure, ZDTP can be used as a component in non-N-nitrosamine generation cure systems. ZDTP is non-discoloring and non-staining. ZDTP is regulated for use in articles in contact with food as specified under Bg VV XXI, category 4, ZDTP is not regulated for use in FDA food contact applicants.

Product Name:

Rubber Accelerator TBzTD

Model:

NURCHEM TBzTD

Description:

TBzTD is a safe secondary amine accelerator; it has been developed to replace thiurams such as TMTD in case where the presence of harmful nitrosoamines is of concern. The dibenzylnitrosoamine is not carcinogenic, according to published literature, TBzTD is a fast curing primary or secondary accelerator in NR, SBR and NBR applications. In modified CR, TBzTD is a retarder when used with ETU. Compared with TMTD, TBzTD is safer processing and has longer scorch time.

Product Name:

Rubber Accelerator TETD

Model:

NURCHEM TETD

Description:

The natural rubber, styrene-butadiene rubber, nitrile butadiene rubber, butyl rubber, cis-butadiene rubber and latex's super accelerator and vulcanizing agent. The active sulfur content is 11%, can be used as the neoprene's modifier. In the rubber, this product is easy to disperse, does not change color, does not pollute, usually uses in making the electric cable, the rubberized fabric, the rubber shoes, the inner tube, the bright color product and so on.

Product Name:

Rubber Accelerator DPTT(TRA)

Model:

NURCHEM DPTT

Description:

Secondary accelerator for NR, SBR, EPDM, and NBR. For rich sulphur content of 28%, it could be used as cure agent. In the system of SBR and NBR, it could be used the primary cure agent. No poison and no pollution. Easily dispersed in rubber system
