The footwear industry is constantly innovating to provide consumers with shoes that offer superior comfort, durability, and aesthetic appeal. A key component in achieving these goals is the material used for midsoles and insoles, often made from EVA (ethylene-vinyl acetate) foam. The performance of EVA foam is significantly influenced by the crosslinking process, and Bis(tert-butylperoxy isopropyl)benzene (BIPB) has become a favored crosslinking agent in this sector.

EVA foam is valued for its lightweight, cushioning properties, and shock absorption. However, to achieve optimal performance, it requires precise crosslinking. BIPB, as a potent organic peroxide, effectively initiates this crosslinking, creating a resilient and durable foam structure. The process involves heating the EVA polymer with BIPB, causing it to decompose into radicals that form crosslinks between the polymer chains. This transformation enhances the foam's ability to return to its original shape after compression, providing lasting comfort and support for the wearer.

A significant advantage of BIPB in footwear applications is its odorless nature. Traditional crosslinking agents often leave a residual chemical odor that can be off-putting to consumers. BIPB's decomposition products are less odorous, ensuring that the finished EVA foam products, such as shoe soles and cushioning inserts, are pleasant to use. This characteristic is particularly important for athletic footwear and children's shoes, where sensory experience is a primary consideration.

Beyond odor, BIPB contributes to the overall performance and durability of EVA foam. The crosslinking process initiated by BIPB improves the foam's resistance to abrasion and wear, ensuring that shoes maintain their integrity and cushioning properties over time. It also enhances the material's resilience, meaning it can withstand repeated impact and stress without collapsing. Furthermore, BIPB offers excellent processing characteristics, including good scorch safety, which is crucial for efficient manufacturing of foam components.
