Materi'act Nafilean Stiff

NAFILean STIFF

A bio-based structural compound with high rigidity and reduced weight – ideal for interior applications requiring stiffness and compatibility with decorative coverings.

NAFILean STIFF is the high-rigidity member of our NAFILean family, engineered for structural applications that require stiffness and dimensional stability, plus lower environmental impact. Reinforced with 20% natural hemp fibres, it offers you a more sustainable alternative to 20% glass-fibre polypropylene (PPGF20) that’s fully compatible with standard injection processes and covering techniques.

Applications

NAFILean STIFF is a great match for your interior structural parts in automotive. We’re also on the case and exploring new applications in other industries.

Your material characteristic checklist 

  • Polypropylene-based compound reinforced with 20% hemp fibre

  • Designed for applications requiring high stiffness

  • Low density vs mineral or glass-filled alternatives

  • Supports covering for aesthetic applications

  • Processable on standard equipment

Structuring sustainability  

NAFILean STIFF helps reduce vehicle weight and emissions by replacing conventional mineral or glass-filled plastics with renewable, low-density hemp fibres. It’s fully recyclable, making it a good choice for circular automotive design, from part production to end-of-life.
