| First PL400-50GE |  |
Chemical composition: Trimethylolpropane trimethacrylate | Complex carrier: EPDM | Characteristics: Auxiliary crosslinking agents used in peroxide vulcanization of materials such as ethylene-propylene-diene monomer (EPDM) rubber, chloroprene rubber, silicone rubber, polyurethane, ethylene-vinyl acetate copolymer (EVA), and chlorinated polyethylene elastomer (CPE); these agents enhance the corrosion resistance, aging durability, hardness, and heat resistance of the final products. They ensure processing without leakage or dust generation, making them easy to weigh and disperse uniformly. During mixing, they act as plasticizers, while during vulcanization, they contribute to increased hardness. Additionally, these agents help reduce radiation dosage, shorten irradiation time, and boost crosslink density. |
| First 101 (Double 25) - 50GE |  |
Chemical composition: 2,5-Dimethyl-2,5-bis(tert-butylperoxy)hexane | Complex carrier: | Characteristics: Used as a crosslinking agent for natural rubber, synthetic rubber, and thermoplastic polyolefins, it features a bifunctional structure. Commonly employed as a crosslinker and initiator in applications such as silicone rubber, chlorosulfonated polyethylene, polyurethane, and EVA. Compared to products like 3M and di-tert-butyl, it offers superior processing safety—no dusting, no leakage, and excellent handling characteristics. Moreover, vulcanized products made with this agent exhibit outstanding physical properties and exceptional heat resistance. |
| First DCP-40GE |  |
Chemical composition: Diisopropylbenzene Peroxide | Complex carrier: | Characteristics: A general-purpose crosslinking agent for natural rubber, synthetic rubber, and polyolefins; pre-dispersed masterbatch offering excellent processing safety—no dusting or leakage during handling. However, products crosslinked with this agent tend to have a strong odor, which can be effectively reduced only through secondary vulcanization. If low odor is required, we recommend using BIBP (odorless DCP) instead. |
| First FL-20 Physical Plasticizer |  |
Chemical composition: A mixture of zinc fatty acid soaps | Complex carrier: | Characteristics: An excellent physical plasticizer for both natural and synthetic rubber, it begins its plasticizing action even at lower mixing temperatures. It effectively accelerates the uniform dispersion of fillers, significantly reducing the mixing cycle time—without compromising the hardness of the vulcanized rubber. Additionally, it exhibits excellent compatibility, prevents blooming, and delivers superior performance when added during the initial stage of one-step mixing. |
| First FM-42 Special Mobile Demolding Agent |  |
Chemical composition: Isopentaerythritol stearate | Complex carrier: | Characteristics: It can reduce the Mooney viscosity of the compound, shorten mixing time, and save energy. Additionally, it increases the extrusion rate of the rubber compound, making it easier to demold products with smooth, even surfaces. This product also eliminates the sticky roller phenomenon commonly seen during open-mill mixing. Furthermore, it boosts extrusion and injection output, significantly enhancing production capacity. Suitable for fluororubber, acrylate rubber, hydrogenated nitrile rubber, and EPDM rubber, among others. |
| First FM-41 Universal Flow Release Agent |  |
Chemical composition: A combination of saturated fatty acid soap salts and a high-performance lubricant | Complex carrier: / | Characteristics: In rubber products such as extrusion molding, complex molds, and microcellular foam, it enhances venting and demolding properties, leading to superior dimensional stability. It also reduces raw rubber viscosity while providing lubricating and dispersing effects, thereby improving the flowability of the compound. In injection molding processes, it increases injection volume—particularly effective in molds with intricate or specialized shapes. This product is compatible with both natural and synthetic rubbers, including NR, SBR, BR, NBR, EPDM, and more. |
| First LF-35 EVA-specific dispersant |  |
Chemical composition: A combination of saturated fatty acids, fatty acid esters, and fatty acid soaps | Complex carrier: | Characteristics: Dispersant suitable for EVA and general-purpose plastics. During the compounding process, it provides excellent lubrication to plastic macromolecules, reducing frictional heat generated between polymer chains and significantly lowering energy consumption during rubber mixing. It effectively prevents filler agglomeration, which can lead to uneven dispersion, thereby markedly enhancing the overall dispersibility of fillers. Additionally, it exhibits outstanding wetting and dispersing properties on fillers, promoting better processing characteristics such as extrusion. In peroxide vulcanization systems, within the recommended dosage range, it has no adverse effects. |
| First LF-31 Carbon Black Dispersant |  |
Chemical composition: A combination of advanced fatty acids, fatty acid esters, fatty acid soap salts, and waxes | Complex carrier: | Characteristics: Applied to both natural and synthetic rubber, it provides excellent lubrication of rubber macromolecules during the mixing process, reducing frictional heat generation between polymer chains, preventing material buildup, and significantly lowering energy consumption in rubber processing. It also exhibits outstanding wetting and dispersing properties for fillers like carbon black, enhancing the processability of the compound during operations such as calendering and extrusion. Importantly, it has no adverse effects on the vulcanization rate or the overall physical performance of the rubber compound. This product is particularly well-suited for use in tire tread compounds, automotive shock-absorbing components, conveyor belts, and other rubber products. |
| First AC3000-75 |  |
Chemical composition: Azodicarbonamide | Complex carrier: EPDM | Characteristics: Commonly used general-purpose high-temperature blowing agents, widely applied in the foaming of rubber and plastics such as PE, PS, EVA, PVC, and rubber-plastic foam products. They decompose at temperatures between 200–210°C and deliver a gas yield of 210–225 ml/g. These agents are extensively utilized in rubber sealing strips, sports equipment, insulation materials, and footwear components. |
| AC7000-75 | |
Chemical composition: Azodicarbonamide | Complex carrier: EPDM | Characteristics: Commonly used general-purpose high-temperature blowing agents, widely applied in the foaming of rubber and plastics such as PE, PS, EVA, PVC, and rubber-plastic foam products. They decompose at temperatures between 200–210°C and deliver a gas yield of 210–225 ml/g. These agents are extensively utilized in rubber sealing strips, sports equipment, insulation materials, and footwear components. |
