Amino solutions for lighter, more comfortable, and more efficient footwear
Reducing weight without giving up performance: a real challenge for the footwear industry
The search for lighter, more ergonomic, and more economical footwear has driven manufacturers to invest in low-density insoles. However, the challenge goes beyond reducing mass: it is necessary to maintain dimensional stability, resistance to use, and the feeling of comfort, without increasing costs or compromising production.
Amino Química develops customized polyurethane (PU) systems for low-density insoles, delivering high technical performance with lightness and industrial efficiency.
Why choose Amino?
Amino’s formulations were developed to overcome the conventional limits of lightweight foams. They are ideal for manufacturers who wish to:
- Reduce the final weight of the footwear without losing performance.
- Reduce raw material consumption per pair.
- Obtain foams with good resilience and tactile comfort.
- Ensure stability and reproducibility in the production process.
With these differentiators, our customers increase the perceived value of their products and gain operational efficiency.
The chemistry of lightness with superior performance
Amino’s low-density PU systems are formulated with:
Optimized polyols
Balance between cellular structure and mechanical resistance, even with mass reduction.
High-efficiency catalysts
Control of gelation and demolding according to cycle time and type of machinery.
Exclusive additives
Proprietary technology that preserves comfort and minimizes permanent deformations.
These elements act in synergy to deliver lightweight foams with technical behavior similar to traditional ones, without compromising cutting, bonding, or lamination.
Low density with high industrial yield
Each production process has its own variables — mold type, ambient temperature, demolding time, fabrics, and applied adhesives. For this reason, Amino acts as a technical partner in the fine adjustment of each PU system, ensuring:
- High reproducibility from batch to batch.
- Full compatibility with existing processes.
- Thermal and dimensional stability, even under demanding conditions.
- Low rate of rework and material waste.
Benefits for your product and your brand
Adopting low-density insoles with high performance brings direct gains to the positioning of your footwear line:
- Greater comfort perceived by the end consumer.
- Superior appearance and finishing, with fewer assembly defects.
- Weight reduction as a commercial differentiator.
- Optimized cost per pair, with preserved performance.
