Product Description

amboflon® PVDF (polyvinylidene fluoride - CAS No.: 24937-79-9) is a high-performance, semi-crystalline thermoplastic resin and it belongs to the group of the Polyhalogenolefins. Available as granule, powder and reinforced compound. Typical applications are chemical plant construction, the food-, medical- and semiconductor-industries.

Characteristics

Depending on the thermal treatment of the parts produced, the crystallinity gets higher or lower. Fast-cooled films, for example, become transparent. Parts tempered at 130-140°C, on the other hand, become highly crystalline and stiff. High frequency applications lead to gradual degradation of the polymer.

Due to its FDA conformity and the general physiological harmlessness of amboflon® PVDF, it is possible to issue safety certificates for manufactured parts made of this material in accordance with Regulation (EC) No. 1935/2004.

Above the decomposition temperature of 375°C, toxic and corrosive fire gases form. Please refer to the Material Safety Data Sheet when processing.

Resistance

amboflon® PVDF is characterized by the highest resistance of all fluoroplastics to high-energy radiation. Right after PTFE, PVDF is the most weather-resistant fluoroplastic. It is highly pure, very resistant to chlorine, bromine and UV radiation. In addition, PVDF exhibits excellent resistance to gasoline, aliphatic hydrocarbons, halogenated solvents, amines, ammonia, anillin, acids, hydrogen peroxide and hot water. Limited resistance has PVDF against benzene, aromatic hydrocarbons and phenols. PVDF is not resistant to esters, ketones, NaOH, KOH and pyridine.

Flammability

amboflon® PVDF is self-extinguishing and is therefore classified according to UL-94 (DIN EN 60695-11-10) in V-0.

Processing

Process: injection molding, extrusion, coating

Processing temperatures:

Extrusion, injection molding: 200 - 270°C (tools 60 - 90°C)

Coating (casting, dipping, spraying): 190 - 215°C

The PVDF melt must not come in contact with boron-containing materials (cylinder, screw, etc.) or MoS2. This can lead to the degradation of the melt. In addition, only amboflon®-color masterbatches and fillers recommended by us should be used. Bonding with adhesive lacquers or two-component adhesives as well as the usual welding processes are applicable.
