Infinergy® Integrated TPU Midsole Platform Upgrade: All-Round E-TPU Foaming Technology
Written by Yate New Materials
1. Industry Background & BASF’s Strategic Upgrade

Movement performance is the core pursuit of modern sports footwear. As footwear brands shift their focus from single material parameters to the full chain integration of materials, production craftsmanship, function and design, BASF officially announced a major upgrade for its iconic Infinergy® E-TPU series.
Previously positioned as a standalone E-TPU raw material, Infinergy® has now been reconstructed as a holistic, integrated TPU midsole technology and innovation platform, named “One TPU Platform, Infinite Possibilities in Midsole & Beyond”. This upgrade fully matches the multi-dimensional R&D and production demands of global sports and casual shoe manufacturers.
2. Four Mainstream Foaming Technologies Covered by New Infinergy® Platform
The updated Infinergy® system supports every mature industrial foaming process currently applied to shoe midsoles, eliminating compatibility limits for footwear factories with different production lines:
- Pellet bead foaming: Standard expandable E-TPU pellets for mass-production bead foam midsoles
- Autoclave shoe preform foaming: “Small expand to large” molding for integrated shoe midsole blanks
- Autoclave sheet foaming: Continuous foamed TPU sheets for cutting, compounding and customized shape processing
- SCF supercritical injection foaming: Advanced one-step injection foaming for seamless, complex midsole designs
3. New Aliphatic E-TPU Grade: Ultra-Lightweight & High Rebound
A landmark aliphatic-grade E-TPU material is newly launched within the Infinergy® product portfolio, bringing revolutionary physical properties for high-end footwear:
- Minimum density: 0.08 g/cm³, drastically cutting down shoe weight
- Max rebound rate: Up to 80%, delivering responsive cushioning for running, basketball and training shoes
This aliphatic formula also boasts excellent anti-yellowing performance, perfectly fitting bright-color and long-life sports shoe requirements.
4. Customized Midsole Solutions for Diverse Footwear Scenarios
Built on the complete Infinergy® TPU platform, tailored material formulas and foaming solutions can be developed for all footwear categories:
- Professional running shoes
- Fitness & training sneakers
- Fashion casual shoes
- Outdoor hiking footwear
Designers and manufacturers can freely adjust density, hardness, elasticity and molding techniques according to product positioning, without being restricted by single material specifications.
5. Cross-Industry Application Extensions
The performance advantages of Infinergy® E-TPU are not limited to shoe midsoles. The versatile foam material can be widely applied across consumer goods sectors:
- Shock-absorbing components for tennis rackets and sports equipment
- Soft, safe elastic pet toys
- Lightweight buffer cushions for baby strollers
- Elastic padding for protective gear
