General Information

High-quality technical plastic for chemical apparatus and machine building, especially in the petrochemical, metallurgical, pharmaceutical, food processing, paper and textile industry as well as in the nuclear technology.

Chemical features:

Resistant to alcohols, fats and oils, alkalis, acids and halogens; limited resistance to oxidizing acids; poor resistance to ketones, amines, pyridine, dimethyl formamide, hot alkalis and fuming sulfuric acid.

Material specification:

PVDF has similar properties than the related PTFE (temperature range -60 °C to +150 °C)

PVDF is vastly superior to all other fluoropolymers concerning stability, stiffness and creep strength as well as resistance to high-energy radiation, but sliding and electrical insulating properties are a little weaker.

Excellent resistance to UV, aging and weather

Good abrasion resistance

Good dielectric strength

Good dimensional stability due to strong hardness

High stability and impact resistance even at low temperatures

Low dissipation factor

Can not be solvent cemented

Water resistant

Flame resistant

Physiologically safe

Meets highest purity requirements

Material: PVDF (polyvinylidene fluoride)

Colour: natural, slightly translucent

Density: 1.76 g/cm3 (DIN ISO/IEC 1183)

Temperature range: -40 to +150 °C, for a short time +160 °C

Melting point: +175 °C (ASTM 03418)

Elastic modulus: 2,500 MPa (ISO 527)

Yield stress: 57 N/mm2 (DIN 53455)

Tearing strength: 50 N/mm2 (DIN 53455)

Elongation at break: 12 % (DIN 53455)

Coefficient of sliding friction against steel (dry): approx. 0.20 - 0.35

Water absorption: <0.04 % (ISO 62), storage in water

Shore hardness D: 79° (ASTM D2240)

Impact resistance: 300 - 450 kJ/m2 (DIN 53448)

Volume resistivity: 1013 Ohm x cm (IEC 60093)

Dielectric strength: 40 kV/mm (IEC 60093)

Flammability: hardly inflammable, self-extinguishing
