Biofibre® Sustra

Biofibre® Sustra - virgin

Biofibre® Sustra - recycle

Biofibre® Sustra fits perfect when you want to wash your previously used standard plastics “green” by supplying bio-based materials in the compound. Processing capabilities and product properties are almost equivalent to traditional petroleum based plastics (e.g., PE, PP). The bio-based proportion here is at least 20%.
Biofibre® Sustra is available as standard in 2 versions, in food approved quality and alternatively in recycling quality with as many recycled materials as possible.
The name “Sustra” is derived from the English “sustainability” and thus symbolizes the emphasis on sustainability of this product group.

Sustainable and biobased!

  • Engineering grade based on polypropylene and wood fibres
  • Suitable for production of complex articles with long flow paths at very low wall thicknesses.
  • Excellent processability, excellent surface finishing, dyeable with standard color masterbatches.
  • Typical markets are within applications were high temperature resistance, very short processing times, and low density is desired
  • Typical markets are within consumer articles, furniture industry, water-contact applications, automotive parts and rigid packaging.
  • Drop-in for e.g. PP, HDPE
  • Example: Flower pot with very thin walls
