Recycled rubber additives: Due to the non-polar part of the plasticizer being sandwiched between the polar rubber molecular chains, it acts to push apart the molecular chains, further weakening the intermolecular forces between the rubber chains, making it easier for the rubber molecular chains to move, showing increased plasticity. Internal release agents are used during the mixing process in rubber product manufacturing, providing excellent demolding effects on the compounded rubber, improving the fluidity of the rubber compound, preventing the formation of waste material, increasing the yield of qualified products, and saving energy and reducing consumption. They make the products easy to demold, enhance surface luster, and possess excellent thermal stability. External release agents are produced by spraying a diluted solution into the mold cavity. Internal release agents are added according to the percentage of the production raw materials.

Rubber Additive Recycling: Compared to sulfur, rubber accelerators in the curing system, the application of anti-aging agents is not as urgent. This is because the mainstream anti-aging agents such as IPPD, 6PPD, and RD are easier to mix and use. They should be evenly dispersed in the base rubber and can be added at the early stage of mixing to ensure sufficient dispersion time. Of course, for high-quality rubber products, pre-dispersed antioxidant masterbatches are still a very necessary choice. Currently, to reduce dust pollution and improve measurement efficiency and accuracy, various additive manufacturers have adopted powder granulation technology to produce rod-shaped small particles. This type of product is sure to be welcomed by rubber product companies.

Superior rubber additives not only enhance processing properties and improve product quality, but also reduce energy consumption and production costs, while preventing aging and degradation, thus extending service life.

Rubber Additive Recycling: Rubber accelerators are primarily small organic molecules. Compared to sulfur, they have better compatibility with the rubber matrix. However, due to their low quantity and even distribution in rubber, they significantly affect product performance. Moreover, in most cases, sulfur is added to the accelerators during the later stages of mixing in an open mixer, making it meaningful to prepare pre-dispersed accelerator masterbatches, especially for commonly used accelerators like TBBS, CBS, and CBS masterbatch products. The DM in the tire industry. The application prospects are very promising.
