PVDF Polyvinylidene fluoride

PVDF belongs to the group of fluorine-containing thermoplastics whose most well-known member is Teflon® (PTFE). In terms of chemical structure PVDF is related to PVC but on account of the fluorine atoms it has a more stable chemical structure.

The partially crystalline PVDF is manufactured both by emulsion polymerisation and by suspension polymerisation. Owing to technical progress in polymerisation technology PVDF can be manufactured with a very high degree of purity so it can be used in high-purity applications in medical equipment and in the semiconductors industry.

Polyvinylidene fluoride (PVDF) belongs to the highly crystalline thermoplastics. Its molecular structure and high crystallinity provide PVDF with high rigidity, even in the upper temperature range. The excellent chemical resistance means the material has a wide range of applications. PVDF is also physiologically safe and has low flammability.

Owing to their high chemical resistance and thermal stability fluoroplastics are used in installation construction and as pipelines, especially in the chemical industry. Their properties depend on the respective fluorine content. The higher the proportion of fluorine the higher the continuous service temperature, flame resistance and chemical resistance.

SIMONA® PVDF has a fluorine content of approx. 57%, which guarantees high chemical resistance up to temperatures of 140°C. The chemical resistance is dependent on the medium to which it is exposed. PVDF only shows weaknesses in the alkaline range, when the pH is above 11.

The high rigidity of PVDF means it is an ideal structural material for high technical demands.
