Nanovia ISTROFLEX : Biodegradable flexible

7,15 121,05  exl. VAT

Nanovia Istroflex is a biodegradable flexible FFF filament (Shore 44D / 93A). Composed out of cosmetic grade oyster powder sourced in France (Morbihan) combined in a biodegradable polymer matrix. Compostable according to norm EN 13432, this filament is certified without endocrine disruptors. Nanovia Istroflex is characterized by a very good build plate and inter layer adhesion.

Using Nanovia Istroflex, biodegradable oyster shell based composite 3D filament, 3D print every day use flexible projects.

Its flexibillity is perfectly suited for technical parts that require a certain amount of give or bounce such as shock and vibration absorbers, silent blocks, gaskets, interstitial constricted materials, etc…

Developed in conjunction with the technical platform ComposiTIC and Usine de Kervellerin in 2015, Nanovia Istroflex 3D filament was awarded the CCI Morbihan innovation award.

Application recommendations


  • Store Nanovia Istroflex in a dry and dark location, if possible with a desiccant.
  • In order to guarantee good printing conditions dehydrate Nanovia Istroflex at 60 °C for 4 hours or longer, when the spools has been exposed to moisture for an extended period.


  • Extrusion temperature : between 210 and 230 °C
  • Heated bed temperature : between 20 and 40 °C

Post treatment

  • It is possible to sand thick layers of Nanovia Istroflex.

Health and safety


Nanovia Istroflex contains is a heavy polymer, based on biodegradable monomers and cosmetic grade oyster shells.

Food safety

Nanovia’s Istroflex’s raw materials conform to European Commission’s ruling n°10/2011: materials and plastic objects destined to come into contact with food ; modified on February 5th 2015 by UE ruling n°2015/174.

According to this ruling, the migration should be measured on finalized products in contact with food wares in standard temperature and duration conditions.

Please consult the material safety sheet for more information.

RoSH certification

  • Nanovia Istroflex RoHS certification: Nanovia Istroflex certified RoHS

Endocrine disruptor test:

1 Method OEDT – SERPBIO Laboratory. Sample : NANOVIA 3D filament Istroflex.

Study: Measuring the activity of the human estrogenic receptors expressed in S. cerevisiae (SW303.1B)

Every measurement is reproduced 3 times independently with the different contents of the tested sample

Results: The obtained data shows that the tested product does not influence the measured activity

Note on the ratio of circulating plasmic œstradiol: With menopaused women / with men: * [4×10-11M – 2×10-10M] with pre menopaused women (excluding ovulation): [1×10-10M – 5×10-10M] / with women (ovulation): [2×10 -9m] * a value is considered critical when it exceeds [2×10-11M].

CONCLUSION: The tested material can be considered absent of endocrine disruptors.


Spools are packed in individual boxes, sous-vide with desiccant. Spools are equipped with both a material traciblity and production series number.

Other sizes available up to 25kg on demand.
