1.New Elastomers: SEBS-based TPE/TPU
Density is generally lower than traditional rubber, making the material itself lighter.
By adjusting hardness (which can be as low as Shore 10-15A), it achieves a soft, foldable touch similar to silicone.
Integrated molding, environmentally friendly, and durable.Case Study: TPE rain boot patent by Guangdong Honglizi Company.
2.Bio-based Rubber: Bio-based Itaconate Rubber (Derived from Corncobs)
Structural optimization of bio-based materials reduces weight.
Molecular structure design provides rubber elasticity, while delivering a soft, odor-free hand feel.
Environmentally friendly and carbon emission-reducing.Case Study: "Corn Boots" by Hangzhou Kunpeng Rubber.
3.Bio-based Foam Materials: Bio-based EVA (Derived from Sugarcane, etc.)
The foam structure contains a large number of air bubbles, significantly reducing weight.
The foam material itself offers a soft and cushioned foot feel.
Partially replaces petroleum-based materials.Case Study: Veja children's shoes use sugarcane-based bio-based EVA midsoles.
4.High-performance Foam Particles: ETPU (Popcorn Foam)
Supercritical fluid foaming technology creates a micro-airbag structure, achieving ultimate lightweighting.
Foam particles provide high resilience and a soft, comfortable stepping feel.
High resilience, yellowing resistance, and recyclable. Commonly used in high-end shoe midsoles.
5.Composite Elastomer Materials: Ultra-light Elastomer Compositions (e.g., blending of multiple elastomers)
Density is reduced through material formulation and blending foaming processes.
Modified molecular chain fusion enhances overall softness and elasticity.
Balances performance to achieve a combination of lightness, softness, and elasticity.Case Study: Relevant patents by Peak Footwear.
