| First MAC-1489 |  |
Chemical composition: Highly Effective Anti-Yellowing Promoter | Complex carrier: EPDM | Characteristics: Outstanding yellowing resistance, achieving grades 4.0 to 5 under stable conditions with other ingredients in the formulation; exhibits a moderate vulcanization speed, resulting in wear resistance, tensile strength, and tear resistance that are comparable to those of standard accelerator-enhanced products. Additionally, it is free from contamination and discoloration, ensuring consistent color stability in rubber products—particularly making it ideal for use in rubber shoe soles. This product also boasts excellent scorch resistance when compounded into rubber, allowing it to remain stable at room temperature for 3–5 days, thus overcoming the common issue of short scorch times associated with conventional yellowing-resistant accelerators. It is primarily used in white and light-colored rubber shoe soles, as well as other rubber products. |
| First EM33-75 |  |
Chemical composition: EPDM Comprehensive Accelerator | Complex carrier: EPDM | Characteristics: A comprehensive accelerator specifically designed for EPDM, offering high vulcanization efficiency and excellent vulcanization flatness. It can be used alone or combined with ZDBC and ZDEC for even faster curing rates. This product is non-staining, does not cause discoloration, and disperses easily, making it ideal for white or light-colored rubber products. It is commonly employed in EPDM-based sealing strips, hoses, molded components, and other similar applications. |
| First MAC-3108 |  |
Chemical composition: Environmentally friendly, highly efficient promoter without a thiazole structure | Complex carrier: EPDM/SBR | Characteristics: A comprehensive eco-friendly accelerator suitable for NR, SBR, BR, EPDM, IIR, and other rubbers; it can be used as the primary accelerator on its own or combined with small amounts of TBzTD-75, ZBEC-75, ZDTP-50, and other components to create an environmentally friendly vulcanization system. This system delivers rapid curing speeds while completely eliminating the thiourea structure, ensuring a non-bitter taste. Importantly, no nitrosamine carcinogens are produced during the vulcanization process. During storage, the product may gradually change from pale yellow to gray, though it remains non-staining to rubber. |
| First ZBPD-50 |  |
Chemical composition: Zinc O,O-dibutyl dithiophosphate | Complex carrier: EPDM | Characteristics: A fast-acting vulcanization accelerator for NR and EPDM; it exhibits no blooming, disperses easily, and ensures stable product performance. Featuring a non-amine structure, it is commonly used in vulcanization systems designed to avoid nitrosamine formation, while also demonstrating excellent resistance to reduction. This product is frequently employed in light-colored, vibrant-colored, and white rubber products. Additionally, it can serve as a secondary accelerator in place of DPG, helping to reduce the toxicity of DPG in rubber compounds. When manufacturing articles intended for food contact, compliance with Class 4 regulations outlined in BgVV XXI is required; however, no specific FDA guidelines currently exist for food-contact applications. |
| First ZDTP-50 |  |
Chemical composition: Zinc dialkyldithiophosphate | Complex carrier: EPDM | Characteristics: As a rapid vulcanization accelerator for NR and EPDM, it features a non-amine structure, making it ideal for use in vulcanization systems that eliminate nitrosamine formation while maintaining excellent anti-reduction properties. In effective sulfur-based curing systems, the resulting vulcanizates exhibit outstanding heat resistance. Additionally, when incorporated into NR or EPDM compounds containing sulfur, zinc oxide, thiazole-based, and thiuram accelerators, this product serves as both a primary and co-accelerator, promoting high cross-linking levels and ensuring safe processing conditions. When used in the manufacture of articles intended for food contact applications, compliance with Class 4 regulations outlined in BgVV XXI is mandatory. However, no specific guidelines currently exist regarding its use in FDA-approved food-contact applications. |
| First CDD-80 |  |
Chemical composition: Copper dimethyldithiocarbamate | Complex carrier: EPDM | Characteristics: Rapid vulcanization accelerators for NR, SBR, NBR, IIR, and EPDM systems—particularly well-suited for SBR, IIR, and EPDM formulations. These accelerators enhance vulcanization efficiency more effectively than TT or PX, but they are prone to scorching. To improve the safety of rubber compounds, thiazole- and sulfonamide-based accelerators are commonly used. Notably, in thiazole-based accelerator systems—whether used alone or as co-accelerators—this product requires the lowest dosage. Additionally, this compound exhibits slight rubber staining properties. |
| First TDEC-75 |  |
Chemical composition: Diethyl dithiocarbamate telluride | Complex carrier: EPDM | Characteristics: Used as an ultrafast vulcanization accelerator for rubbers such as NR, SBR, NBR, EPDM, and IIR; commonly employed as a co-accelerator with thiazole, thiuram, and dithiocarbamate-based accelerators. For IIR or EPDM compounds that vulcanize relatively slowly, as well as low-hardness formulations containing high levels of softening oils, it significantly reduces curing time and enhances cross-link density. Non-toxic, slightly odorous, easily dispersible, simple to weigh, and characterized by minimal processing loss. Particularly well-suited for continuous vulcanization, resulting in products with excellent rigidity. |
| First ZnEPDC (PX)-75 |  |
Chemical composition: Zinc ethylphenyl dithiocarbamate | Complex carrier: EPDM | Characteristics: A highly effective accelerator that is relatively safe to use with natural rubber, styrene-butadiene rubber, and nitrile rubber; it features a low critical vulcanization temperature and exhibits higher activity compared to thiazole accelerators. Vulcanization can be carried out at temperatures ranging from 80°C to 125°C, and it is also suitable for room-temperature curing. ZnEPDC-75 is non-polluting, does not cause discoloration, is odorless, tasteless, non-toxic, easily dispersible, and simple to weigh. It can be used in the production of products intended for food contact, as well as transparent and brightly colored items, medical devices, adhesive tapes, self-vulcanizing adhesives, and more. |
| First ZBEC (ZTC)-75 |  |
Chemical composition: Zinc dibenzyl dithiocarbamate | Complex carrier: EPDM | Characteristics: An ultrafast accelerator for synthetic rubbers such as NR, EPDM, IR, SBR, NBR, and IIR; it belongs to the class of secondary amine dithiocarbamate accelerators and does not generate nitrosamines during vulcanization. Typically used in conjunction with products like TBBS-80 and TBzTD-75, it forms an environmentally friendly vulcanization system. Among all zinc dithiocarbamate accelerators, this one exhibits the best scorch resistance. |
| First ZDEC (EZ)-75 |  |
Chemical composition: Zinc diethyl dithiocarbamate | Complex carrier: EPDM | Characteristics: A leading example of zinc dithiocarbamate salts, widely used as an ultrafast accelerator for both natural and synthetic rubber; it serves as an excellent activator when combined with thiazole- and sulfonamide-based accelerators. Adding small amounts of DM, TMTD, PVI, along with the antioxidant MB, can significantly enhance the storage stability of the rubber compound and delay vulcanization. This product is non-staining, does not cause discoloration, and is odorless, tasteless, non-toxic, and easily dispersible. It is particularly well-suited for white and brightly colored products, as well as transparent applications, and is primarily employed in the manufacture of tires, inner tubes, medical devices, adhesive tapes, and self-vulcanizing products. |
