This high-performance PEBAX polyether block amide raw pellet is manufactured from virgin bulk feedstock. It features highly stable molecular structure, high purity, free of impurities and recycled blends. Consistent foaming performance and exceptional batch-to-batch uniformity are guaranteed. Formulated precisely for supercritical nitrogen and carbon dioxide physical foaming processes, it enables stable formation of refined, uniform closed microcellular structures during physical foaming. The resulting foam features regular cell geometry, consistent cell size and minimal cell irregularities, serving as the core base material for high-end supercritical foamed midsoles.

The material delivers industry-leading ultra-high resilience and outstanding energy return efficiency, significantly cutting kinetic energy loss during running and boosting propulsion, making it the ideal foaming raw material for midsoles of professional marathon racing shoes and premium cushioning running footwear. It also boasts remarkable low-temperature resistance; it stays flexible without embrittlement or loss of cushioning and rebound performance under frigid outdoor conditions, maintaining stable athletic performance all year round. Featuring extremely low specific gravity, it is lighter than conventional foamed EVA and TPU, enabling footwear brands to achieve ultra-lightweight midsole designs, reduce overall shoe weight drastically and deliver a lightweight wearing experience.

It exhibits excellent resistance to compression fatigue. After long-term frequent repeated compression, bending and impact, no obvious slackening, collapse or permanent deformation occurs, preserving full cushioning and high energy return of the midsole over extended service life. The formulation generates low odor without migration of harmful plasticizers, reaching high environmental standards and fully complying with international eco-test specifications for exported premium athletic footwear. Safe and odor-free, it meets strict quality requirements of high-end brands.

These virgin PEBAX pellets are high-performance raw materials exclusively for supercritical physical foaming factories and manufacturers of premium professional sports footwear. Primarily applied to produce ultra-high rebound racing shoe midsoles, cushioning layers for professional marathon footwear, all-round midsoles for high-end training shoes and shock-absorbing structural components for outdoor sports footwear. Widely adopted by top footwear brands focusing on lightweight construction, high energy return and professional athletic performance, suitable for mass production and development of high-end functional sports shoes.

Raw pellets are sealed upon delivery. Keep packages sealed before processing to avoid moisture absorption. If moisture content exceeds standard, dry pellets at constant temperature of 80°C for 3 to 4 hours prior to production to eliminate foaming defects. During production, accurately adjust temperature, pressure and holding time of supercritical foaming equipment according to PEBAX hardness grade to achieve optimal expansion ratio and forming parameters. Always complete small-batch trial foaming before mass production; commence volume manufacturing only after cell structure, rebound rate and forming stability pass inspection.Do not mix with other plastic pellets during processing, otherwise impurities will trigger unstable foaming, uneven cell distribution and reduced resilience. Maintain steady and consistent feeding speed to realize continuous, stable and standardized mass production on the whole production line.

Store raw pellets in dedicated cool, dry and well-ventilated warehouses. Control ambient humidity below 60%. Keep away from rain, moisture, heat sources and direct sunlight. Stack bags neatly; prevent sharp objects from piercing packaging and causing moisture contamination. Immediately reseal leftover materials after unpacking to sustain moisture barrier performance. Follow strict FIFO (First In, First Out) inventory management to guarantee fresh and stable raw materials.

For daily production maintenance, inspect pellet appearance before feeding every day to prevent damp agglomerates and foreign particles entering the production line. Conduct weekly sampling tests for moisture content and fully record batch information to achieve traceability and controllable quality.Important operational note: PEBAX pellets readily absorb moisture. Direct processing of damp pellets easily causes foaming voids, cell rupture and forming defects, therefore pre-drying is a mandatory procedure. Qualified semi-finished foamed products generated during production can be recycled for reprocessing to realize low-carbon circulation and sustainable green manufacturing.
