Ethylene Vinyl Acetate (EVA) foam is a versatile material widely used in everything from footwear and sporting goods to packaging and insulation, owing to its excellent cushioning, flexibility, and shock absorption properties. The performance and longevity of EVA foam products are significantly influenced by the crosslinking process. NINGBO INNO PHARMCHEM CO.,LTD. highlights Bis(tert-butylperoxyisopropyl)benzene (BIPB) as a superior crosslinking agent that enhances EVA foam’s characteristics, particularly by eliminating undesirable odors.

The traditional crosslinking of EVA foam often involves agents like Dicumyl Peroxide (DCP), which, while effective, can leave behind an unpleasant odor. This odor is a significant concern for consumer products, especially those intended for close contact with skin or for children. BIPB, known for its odorless crosslinking agent BIPB 96 properties, provides a solution. Its decomposition products are volatile and non-irritating, ensuring that the finished EVA foam products are free from the characteristic chemical smell, thereby improving the overall user experience and product appeal.

Beyond odor reduction, BIPB offers enhanced crosslinking efficiency for EVA. Manufacturers find that using BIPB can lead to products with improved mechanical properties, such as better tear strength and higher resilience. As a peroxide curing agent BIPB, it facilitates a controlled and effective curing process, leading to more uniform cell structures within the foam and greater durability. The benefits of BIPB over DCP in EVA foam applications also include improved resistance to heat and aging, ensuring that the foam maintains its performance characteristics over time and under varying conditions.

The application of BIPB in BIPB for EVA foam manufacturing is straightforward. It can be incorporated into the EVA compound during the mixing stage, and upon heating, it initiates the crosslinking reaction, creating a stable, three-dimensional polymer network. This process not only enhances physical properties but also contributes to the foam’s structural integrity. NINGBO INNO PHARMCHEM CO.,LTD. ensures the supply of high-purity BIPB to guarantee consistent results for EVA foam producers.

The growing consumer awareness and demand for safer, more pleasant products are driving manufacturers to seek out advanced materials and additives. By adopting BIPB, companies can differentiate their EVA foam products, offering superior quality, enhanced safety, and a better sensory experience. NINGBO INNO PHARMCHEM CO.,LTD. is proud to support this industry evolution by providing innovative chemical solutions that meet the highest standards of performance and user satisfaction.
