|---|---|---|---|---|
| First LF-36 Speciality Mobile Dispersant |  |
Chemical composition: A combination of saturated fatty acids, fatty acid soap salts, and fatty acid amides | Complex carrier: | Characteristics: Reduces the Mooney viscosity of the compound, shortening mixing time and saving energy. Enhances the extrusion rate of the rubber compound, making it easier to demold products with smooth, even surfaces. Eliminates the sticky roller phenomenon commonly observed during open-mill mixing. Increases extrusion and injection output, boosting overall production capacity. Importantly, it has no adverse effects on vulcanization speed or the physical properties of the rubber compound. Suitable for specialty polar rubbers such as FKM, ACM, AEM, ECO, EO, CSM, and HNBR. |
| 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-34 Universal Flowing Dispersant |  |
Chemical composition: A combination of advanced fatty acids, fatty acid esters, fatty acid soap salts, and waxes | Complex carrier: | Characteristics: As a versatile flow agent, it is particularly well-suited for internal mixing processes and can be used effectively in NR, SBR, BR, NBR, EPDM, and other rubber compounds. It significantly improves the Mooney viscosity of raw rubber, lowers the internal mixer temperature during compounding, reduces energy consumption, and prevents premature scorching. Additionally, it enhances the roll sticking properties of the compound, minimizes die swell during extrusion, and boosts the smoothness of the final product surface. This results in increased output from injection and extrusion processes, fewer defective products, and a lower overall production defect rate—without negatively impacting vulcanization speed or the physical properties of the rubber compound. |
| First LF-33 Extrusion-Specific Dispersant |  |
Chemical composition: A combination of saturated fatty acids, fatty acid soap salts, and fatty acid amides | Complex carrier: | Characteristics: As a flow dispersant, it is particularly well-suited for mixing processes in internal mixers and can be used with both natural and synthetic rubbers, including NR, SBR, BR, NBR, EPDM, and more—especially effective with EPDM. This product helps reduce the Mooney viscosity of the compound, lowering processing temperatures during mixing and preventing premature scorching. It also enhances the processability of the rubber compound, reducing extrusion swell and resulting in smoother product surfaces. Additionally, it increases output rates for injection and extrusion processes, minimizes defects, and lowers overall production scrap rates—all without negatively impacting the curing speed or the final physical properties of the rubber compound. |
| First LF-32 White Carbon Black Dispersant |  |
Chemical composition: A combination of fatty acids, fatty acid soaps, and fatty acid esters | Complex carrier: | Characteristics: During the mixing process, it effectively prevents the aggregation of silica, which could lead to uneven dispersion, thereby significantly enhancing the dispersibility of silica. It exhibits excellent wetting and dispersing properties for fillers like silica, promoting better processability during operations such as calendering and extrusion. Importantly, it has no adverse effects on the vulcanization rate or physical properties of the rubber compound, making it suitable for use in both natural and synthetic rubbers. |
| 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. |
