| First MAC-2108 |  |
Chemical composition: Highly Efficient Comprehensive Promoter | Complex carrier: EPDM/SBR | Characteristics: Commonly known as Accelerator 2#, this product is a versatile accelerator suitable for NR, SBR, BR, IR, NBR, and other rubbers. It offers a moderate vulcanization rate with excellent flatness during the curing process. It can be used as the primary accelerator or combined with accelerators from the thiuram, guanidine, and aldehyde-amine families to further enhance the curing speed. This accelerator is ideal for both light-colored and dark-colored rubber products, such as footwear, balls, and hoses, and is particularly well-suited for thick-walled items as well as applications requiring extended scorch times. |
| First MAC-1108 | |
Chemical composition: Highly Efficient Comprehensive Promoter | Complex carrier: EPDM/SBR | Characteristics: Suitable for use as a general-purpose accelerator in NR, SBR, BR, IR, NBR, and other rubbers, it offers a relatively fast curing speed and excellent cure flatness. It can be used as the primary accelerator or combined with accelerators from the thiuram, guanidine, and aldehyde-amine families. This product is ideal for both light-colored and dark-colored rubber products, including items like footwear soles, balls, and hoses. |
| 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. |
