It can also serve as a scorch retarder and tackifier. It is used in rubber components such as shoulder rubber and breaker layers in load-carrying tires to address shoulder voids in bias-ply truck tires. HVA-2 can also serve as a co-vulcanizing agent, improving related properties and thermal stability. It is suitable for high-temperature vulcanization systems, significantly reducing compression set. It can also reduce peroxide usage, prevent scorching during processing, and improve the bond strength between the rubber and cord and metal.   1. As a multifunctional rubber additive, HVA-2 can be used as both a vulcanizing agent and a co-vulcanizing agent in peroxide systems during rubber processing. It can also serve as a scorch retarder. It is suitable for general-purpose rubber, specialty rubber, and rubber-plastic hybrid systems.   2. In natural rubber, when combined with sulfur, it prevents reversion, improves heat resistance, reduces heat buildup, resists aging, and enhances rubber-cord adhesion and vulcanized rubber modulus. Used in rubber components such as shoulder rubber and cushioning media in load-carrying tires, it can address the shoulder void problem in bias-ply truck tires. It can also be used in large-format, thick-walled natural rubber products and various rubber miscellaneous products.   3. As a co-vulcanizing agent in specialty rubbers such as fluoroprene, fluorosulfonated polyethylene rubber, styrene-butadiene rubber, nitrile rubber, isoprene rubber, butyl rubber, bromobutyl rubber, acrylic rubber, silicone rubber, and rubber-plastic blends, HVA-2 significantly improves related properties and heat resistance. It is suitable for high-temperature vulcanization systems, significantly reduces compression set, reduces peroxide usage, prevents scorching during processing, and enhances the bond strength between the rubber and cord and metal.   4. HVA-2 is a sulfur-free vulcanizing agent. It can replace all slag-containing vulcanizing agents such as those in cable rubber, and solves the problem of copper wire and copper electrical appliances being polluted by sulfur generated by connecting sulfur.   If you have any technical questions about HVA-2 ,pls contact us!         

PDM (N,N'-m-phenylene bismaleimide)  manufactured by Yangchen Tech is used as an anti-scorch agent. The mechanism of inhibiting early vulcanization during rubber processing is mainly related to its chemical properties and mode of action in rubber formulations. Here are the main aspects of how PDM inhibits early vulcanization of rubber:     Delayed vulcanization reaction: Vulcanizing agent PDM can react with vulcanizing agents (such as sulfur) in rubber to form a temporary, inactive vulcanizing agent intermediate. This intermediate is relatively stable at processing temperatures and will not immediately participate in the vulcanization reaction, thereby delaying the vulcanization process. This gives the rubber a longer processing time window, reducing the risk of early vulcanization.   Competing with vulcanization accelerators: In rubber formulations, the role of vulcanization accelerators is to accelerate the vulcanization reaction. PDM can compete with the vulcanization accelerator and form a stable complex with the vulcanization agent, thereby reducing the effective contact between the vulcanization accelerator and the vulcanization agent and slowing down the vulcanization speed. This helps maintain the stability of the rubber during processing and avoid premature vulcanization.   Thermal stability: Vulcanizing agent PDM  itself has high thermal stability and can remain stable at high temperatures without initiating or accelerating vulcanization reactions. This helps maintain rubber stability and processability during rubber processing, especially under high temperature conditions.   Adjust the vulcanization curve: PDM can change the vulcanization curve of the rubber, making the vulcanization reaction gentler and reducing the peak period of the vulcanization speed. This helps avoid aggressive vulcanization reactions in the rubber during processing, thereby reducing the risk of premature vulcanization.   Vulcanizing agent PDM effectively inhibits the early vulcanization of rubber by delaying the vulcanization reaction, competing with vulcanization accelerators, improving thermal stability, and adjusting the vulcanization curve. This makes PDM an important anti-scorch agent that can improve product quality and processing efficiency during rubber processing.   Technical indicators: Appearance Yellow powder Melting point ≥196℃ Moisture content ≤0.5% Ash content ≤0.5%   If you have any questions or need us to provide technical service support,pls feel free to contact: business@xysjgm.com  

Introduction: In the world of tire manufacturing, achieving the perfect balance of performance, durability, and safety is paramount. As technology advances, so too do the materials and processes used in tire production. One such material making waves in the industry is N,N'-1,3-Phenylenedimaleimide (PDM), a tire vulcanizing agent that is revolutionizing tire processing. In this blog, we'll delve into the role of PDM as a high-performance material in tire manufacturing and explore its benefits and applications. Understanding Tire Vulcanizing Agents: Before we dive into the specifics of PDM, let's first understand the concept of tire vulcanizing agents. Vulcanization is a chemical process used to strengthen rubber by crosslinking its polymer chains. Vulcanizing agents play a crucial role in this process by facilitating the formation of crosslinks, which enhance the mechanical properties and durability of the rubber. Introducing N,N'-1,3-Phenylenedimaleimide (PDM): PDM manufactured by Yangchen Tech is a specialized type of maleimide compound that serves as an effective vulcanizing agent in tire manufacturing. Its unique chemical structure and properties make it an ideal choice for enhancing the performance of rubber compounds used in tire production.   Technical indicators:   Appearance Yellow powder Melting point ≥196℃ Moisture content ≤0.5% Ash content ≤0.5%   Benefits of Using PDM in Tire Processing:   Improved Mechanical Properties: PDM facilitates the formation of strong crosslinks within the rubber matrix, resulting in enhanced tensile strength, tear resistance, and wear resistance of tires. This leads to longer-lasting tires that can withstand the rigors of daily driving. Enhanced Heat Resistance: Heat buildup is a common challenge faced by tires, especially during high-speed driving. PDM helps improve the heat resistance of rubber compounds, ensuring that tires maintain their integrity and performance even under extreme temperature conditions. Optimized Performance: By fine-tuning the formulation and concentration of PDM, tire manufacturers can tailor the properties of tires to meet specific performance requirements. Whether it's optimizing grip for improved traction or enhancing fuel efficiency, PDM offers versatility in tire design.   Applications of PDM in Tire Manufacturing: PDM finds widespread use in the production of various types of tires, including passenger vehicle tires, commercial truck tires, and performance racing tires. Its ability to improve the mechanical properties and heat resistance of rubber compounds makes it a valuable addition to tire manufacturing processes across the globe.   As tire manufacturers strive to push the boundaries of performance and innovation, high-performance materials like N,N'-1,3-Phenylenedimaleimide (PDM) play a crucial role in achieving these goals. By enhancing the mechanical properties, durability, and heat resistance of tires, PDM is driving advancements in tire technology and paving the way for safer, more efficient, and more sustainable transportation solutions.     If you have any questions,pls feel free to contact: business@xysjgm.com
