At Greenfib, we recognize the importance of clarity, sharing knowledge, and building responsibly. Etymologically, ecology means “knowledge of the house,” while economy refers to “management of the house.” We believe in providing a solid answer to a well-posed question. This article aims to contribute to a better understanding of bioplastics, taking the role of educator rather than claiming absolute expertise.
Greenfib®: A High-Performance Polymer (HPP)?
High-performance polymers (HPPs) are distinguished by their ability to operate reliably in extreme environments, such as high temperatures, chemically aggressive media, or under significant mechanical stress. They retain their functional characteristics under these conditions thanks to excellent thermal stability, long service life, and strong resistance to chemical degradation. These qualities explain why HPPs are widely used in advanced engineering applications.
PA11: A High-Performance Polymer
Polyamide-11 is a long-chain aliphatic polyamide that is 100% bio-based, derived from castor oil, and has been commercialized for over eight decades.
Its classification as a high-performance polymer is based not on extreme heat resistance—its melting point is approximately 186°C—but on a balanced set of physical, physico-chemical, and mechanical properties without major weaknesses. Additional advantages include:
- strong resistance to hydrolysis, fuels, petroleum products, and certain salts.
- outstanding performance at very low temperatures (down to −60°C), particularly in terms of impact resistance and deformability,
- relatively straightforward processing,
Greenfib®: A Charged High-Performance Polymer
Patented in 2011, Greenfib® incorporates PA11 as its base. Building on this robust, well-recognized polymer, we integrate natural fillers:
- Organic: wood, reed, sea silk
- Mineral: oyster shells, marble powder
This combination creates a technical and visually appealing composite, with a pleasant texture and a distinctive natural appearance. For these reasons, Greenfib® can be classified as a Charged High-Performance Polymer.
Greenfib® is manufactured close to its point of use, leveraging a local industrial supply chain. Its properties include:
- dimensional stability from −40°C to +130°C,
- high resistance to impact, tensile, and flexural stresses (tested to current ISO standards),
- self-extinguishing behavior, tested up to 960°C (glowing filament) and classified V2 according to UL94,
making it suitable for technical applications such as switches, sockets, and automotive parts, with a density of 1.05 g/cm³.
Greenfib® is also fully compatible with standard industrial processing equipment—injection molding, extrusion, 3D printing—allowing manufacturers to integrate it seamlessly into their production lines.
In short, Greenfib® represents the ideal material for combining traditional manufacturing techniques with ecological coherence.
Frequently Asked Questions: High-Performance Polymers
1. What are the main applications of High-Performance Polymers?
The automotive industry is a major field of application for many HPPs. However, due to their high cost, their use is generally limited to smaller components, such as seals, washers, bearings, and specific elements of gearboxes and braking systems. Some HPPs are also used as functional coatings.
