Bio-based Polyamide 11 Elastomer
PA11 Elastomer
PEBAX Replacement — Renewable Feedstock, Comparable Performance
The PA11 Elastomer project uses bio-based (castor-oil) PA11 as the backbone, addressing PEBAX's limitations in renewable feedstock supply and carbon footprint, targeting high-end footwear applications requiring sustainable high-performance materials.
Property
Full KPI Set
Includes the 3 confirmed headline metrics + other advanced metrics. Status column indicates confidence source for each data point.
| Property | Value | Status | Note |
|---|---|---|---|
| Base Resin | PA11 (bio-based) | Structural | Castor-oil source; cradle-to-gate carbon significantly lower than fossil PA12 |
| Target Density | < 1.05g/cm³ | Pending · Awaiting Validation | Targeting PEBAX 1.05 typical value |
| Target Hardness | TBDShore A | Pending · Awaiting Validation | Under formulation tuning |
| Target Rebound | ≥ 70% | Pending · Awaiting Validation | Targeting PEBAX 70-75% typical value |
| Carbon Footprint | TBD | Pending · Awaiting Validation | Expected below fossil PEBAX (~8.0); on par with Pebax Rnew® bio (~2.5) |
Design Advantages
Material Design Advantages
Key levers from chemical structure to processing characteristics
Stable Renewable Feedstock
Castor bean has short growth cycles, no food competition, decoupled from fossil supply chains.
PEBAX-Grade Performance
Targets alignment with PEBAX rebound and density characteristics, providing equivalent athletic performance for high-end footwear.
EU DPP / Brand Carbon Commitment Friendly
Bio-attributed feedstock supports brand-level 2030 carbon commitments and EU DPP disclosure requirements.
Benchmarks
Benchmark Against Mainstream Materials
Specific gaps versus TPU and PEBAX
- Expected rebound +15-20% (target ≥70% vs TPU ~55%)
- Density similar (target <1.05 vs TPU 1.20)
- Cost expected higher than TPU, within PEBAX economic range
- Renewable feedstock carbon advantage (PA11 bio-based vs fossil PEBAX)
- Decoupling from fossil supply chain, avoiding occasional PEBAX material shortages
- Performance aligned with PEBAX 70-75% rebound range
