Biofibre® Solva

Biofibre® Solva - virgin

Biofibre® Solva - recycle

This is a compound that has been optimized for biodegradability. At the same time, good processability is ensured. Biofibre® Solva is a compound with optimized properties in terms of biodegradability.
The name “Solva” is derived from the Latin origin “solvere”, what means “to solve” and indicates the biodegradability of this product group.

The compound, which is made of biobased raw materials, also has the ability to degrade in the soil. As soon as the compound is released into nature outside the actual environment of use, the climate and fauna begin their work and gradually decompose the compound into CO2, water and biomass.
Biofibre® Solva can be obtained in standard quality or food grade according to your requirements.

Biodegradable and biobased

  • Blend material made from biopolyestersthat biodegrade in natural environments.
  • combines high flexibility with toughness.
  • Suitable for production of complex articles with long flow pathsat very low wall thicknesses.
  • Excellent processability, excellent surface finishing, dyeable with bio-based color masterbatches.
  • Typical markets are within applications were biodegradability in nature plays a vital role.
  • Can substitute e.g. LDPE, EVA, (PP, HDPE)
