Waterproof IXPP Packaging Foam for Electronics Protection
EKKOFLEX's IXPP (Irradiation Cross-Linked Polypropylene) foam is a waterproof closed cell packaging foam engineered for the protection of electronics and precision instruments. Manufactured from polypropylene through melt mixing and extrusion molding, followed by green ion radiation cross-linking and continuous high-temperature foaming, the material forms an independent closed-cell structure with a closed-cell rate of over 98%.
This unique structure gives IXPP foam outstanding waterproofness and moisture resistance while delivering excellent shock absorption, cushioning, and rebound performance. With low odor and minimal VOC emissions, it is safe for direct contact with sensitive electronic components, making it the ideal protective packaging material for consumer electronics, industrial equipment, and precision instruments in domestic and export logistics.
