Functions:

N,N'-1,3-Phenylenedimaleimide (HA-8/HVA-2/PDM) manufactured by Yangchen Tech is a versatile rubber additive used as a tire vulcanizing agent in rubber processing and peroxide systems. It functions as an anti-scorch agent and tackifier, suitable for various rubbers including neoprene, chlorosulfonated polyethylene rubber, styrene-butadiene rubber, nitrile rubber, isoprene rubber, butyl rubber, bromobutyl rubber, acrylic rubber, silicone rubber, and rubber-plastic composites.

As an auxiliary vulcanizing agent, HA-8 improves cross-linking properties and heat resistance, making it ideal for high-temperature vulcanization systems. It reduces compression permanent deformation, lowers peroxide usage, prevents scorching during processing, and enhances bonding strength between rubber and skeleton materials. Moreover, it addresses concerns such as copper sulfide pollution and blackening caused by sulfur-containing tire vulcanizing agents in copper-related applications. In the adhesive industry, HA-8 serves as a heat-resistant modifier, especially in anaerobic adhesives, effectively enhancing product temperature resistance.

Application on tires:

N,N'-1,3-phenylene dimaleimide (PDM) manufactured by Yangchen Tech is a specific type of maleimide compound used as a tire vulcanizing or cross-linking agent in tire manufacturing. To improve the mechanical properties, durability and heat resistance of the rubber compound, thereby increasing the performance and service life of the tire.

Cross-linking agent: PDM can be incorporated into the rubber compound used in tire manufacturing as a tire cross-linking agent during the vulcanization process. In tire production, natural or synthetic rubber compounds are often reinforced with fillers and additives to improve their properties. During the vulcanization process, these rubber compounds are exposed to heat and pressure, causing them to cross-link and form a three-dimensional network structure that enhances the rubber's mechanical properties and durability.

Improves tire performance: Adding PDM as a tire  cross-linking agent helps improve the performance characteristics of tires. It enhances the rubber's tensile strength, tear resistance and abrasion resistance, making the tire more durable and able to withstand the stresses and strains encountered during normal use.

Enhanced heat resistance: PDM can also improve the heat resistance of the compound, helping the tire maintain its integrity and performance at high temperatures. This is especially important for tires driven at high speeds or heavily loaded, as heat buildup can accelerate tire wear and degradation.

Optimize tire performance: The use of PDM enables tire manufacturers to fine-tune the properties of rubber compounds to meet specific performance requirements. By adjusting the formulation and concentration of PDM, tire manufacturers can tailor the tire's stiffness, flexibility and other properties to optimize performance in different applications such as passenger cars, commercial trucks or racing cars.

N,N'-1,3-Phenyldimaleimide (PDM) is used as a tire vulcanizing agent in tire manufacturing to improve the mechanical properties, durability and heat resistance of rubber compounds, thereby improving tire performance and usage life.
