Customization of Special Vulcanizing Agents in The Rubber Industry

Customer Requirements: 

A rubber products company focuses on producing high-end aviation tires, which are subjected to extremely high pressure, friction, and temperature changes during aircraft takeoff, landing, and flight, and have extremely strict performance requirements for rubber materials. Rubber products made with conventional vulcanizing agents are prone to aging and increased wear under high temperature and high load conditions, which cannot meet the safety and service life requirements of aviation tires. The customer urgently needs a special vulcanizing agent that can improve the cross-linking density and heat resistance of rubber, as well as enhance its wear resistance and fatigue resistance, ensuring the reliability of aviation tires under complex working conditions.

Customized Solution: 

Our R&D team has conducted in-depth research on the molecular structure and vulcanization reaction mechanism of rubber, and developed a new type of organic vulcanizing agent containing multiple functional groups. The vulcanizing agent molecules contain special active groups that can form more and stronger cross-linking bonds with rubber molecules during the rubber vulcanization process, significantly increasing the cross-linking density of rubber. At the same time, high-temperature resistant inorganic nano fillers such as nano silica and nano alumina are introduced. Through special surface treatment techniques, they are uniformly dispersed in the rubber matrix and work synergistically with vulcanizing agents to enhance the heat resistance and wear resistance of the rubber. After multiple rounds of experimental optimization, the optimal sulfurizing agent formula and usage process have been determined to meet the production needs of customers.

Implementation Effect:

Aircraft tires produced using customized special vulcanizing agents have demonstrated excellent performance in rigorous tests simulating aircraft takeoff, landing, and flight. The heat resistance of the tire has been improved by 50 ℃, and after long-term operation in high temperature environments, the rubber hardness and elasticity remain good without obvious aging phenomenon. The wear resistance has been improved by 30%, effectively extending the service life of the tire. The anti fatigue performance has been enhanced. After 100000 simulated takeoff and landing cycles, there are no obvious cracks or wear on the tire surface, meeting the extremely high requirements for tire safety and reliability in the aviation industry. We have helped our clients successfully obtain product certifications from multiple airlines, and our products have been applied to various new aircraft, enhancing their market position and brand influence in the field of aviation rubber products.
