Risks associated with
the use of fluorinated polymers


Client Request

A manufacturer of tubes for oil transport won a new market by proposing a monocoque structure with a new material, PVDF.

If the prototype and the series batches didn’t pose any particular problem, the production was quickly compromised. The quality and productivity must be brought back to the standard defined to meet market demand.

Our Analysis

The company’s tube production history was limited to polyolefins. The switch to PVDF was not accompanied by the material manufacturer. Transforming PVDF under the same conditions as Polyolefins led to serious problems on the material and personnel.

Degradation of a PVDF results in a very corrosive acid that is toxic to personnel, so mastery of the process must be established to reduce and treat the product’s degradation.

Our Solution

SCIPROD immediately implemented a security protocol to protect staff from risks associated with the degradation of fluorinated products.

Training for staff and support teams (maintenance, method) was also carried out quickly. The analysis of the extruder during this training allowed to evaluate the surface state of the tools and correct defects.

Start-up, control, shutdown, and cleaning procedures were put in place with the teams.

Technical assistance for production implementation was carried out after renovating the extruder to establish more stable and secure transformation conditions.

Une assistance technique pour la mise en production a été réalisée après rénovation de l’extrudeuse pour mettre en place les conditions de transformation les plus stables et sécurisées.

The Result

No further degradation of PVDF has been observed since SCIPROD’s intervention. The recordings of the detectors are consistently below the detection limit and the tool has not been in operation since the protocols were put in place (4 months/chronological).
The manufacturer can supply the PVDF tube market with the expected quality and productivity.
