Materials used for industrial pipe work The material polyvinylidenefluoride (PVDF) General Polyvinylidenefluoride (PVDF) is a semi-crystalline thermoplastic having outstanding mechanical, physical and chemical properties. These result from the chemical structure of PVDF. Polyvinylidenefluoride belongs to the class of fluorinated polymers, whose best-known representative is polytetrafluoroethylene (PTFE, trade name: Teflon®). PTFE is characterised by a superb heat resistance and the best chemical resistance of all polymers; a great disadvantage is that it is not melt processable - e. g. into fittings. PVDF, on the other hand, combines various advantages of PTFE with good workability into structural parts. The fluorine content in PVDF amounts to 59 % by weight. PVDF from GF is characterised by a very good mechanical behaviour and high temperature resistance. Because of the exceptionally wide pressure / temperature range in which PVDF can be used, it has opened, in connection with the specific characteristics of this material, completely new areas of application in plastic piping fabrication. These include applications in the semi-conductor, chemical and pharmaceutical industry, electroplating, paper and cellulose processing, the automotive industry and water treatment. Pipes, fittings and valves of PVDF are uncoloured and opaque (milky, translucent). By avoiding the addition of any additives, the outstanding characteristics of the material remain to the fullest extent, especially concerning the chemical resistance and physiological harmlessness. Some of the advantages of PVDF: • outstanding mechanical properties, even at high temperatures • excellent chemical resistance • no electrochemical corrosion • long service life, even under intensely corrosive conditions • outstanding resistance against UV and ³-radiation • very pure material by implementing without additives • no support of microbial growth • physiologically harmless • secure jointing by high-quality welding technology • smooth inner surface • very low heat conductivity • excellent flame retardant properties PVDF properties (reference values) Characteristics Value Units Test Standard Density 1.78 g/cm³ EN ISO 1183 Yield stress at 23 °C > 51 N/mm² EN ISO 527-1 Tensile e-modulus at 23 °C > 1800 N/mm² EN ISO 527-1 Charpy notched impact strength at 23 °C > 9 kJ/m² EN ISO 179-1 Charpy notched impact strength at 0 °C > 8 kJ/m² EN ISO 179-1 Ball indentation hardness (358N) > 115 MPa EN ISO 2039 Heat distortion temperature HDT A 1.80 MPa > 113 °C EN ISO 75-2 Crystallite melting point 173 °C DIN 51007 Thermal expansion coefficient 0.12 ... 0.18 mm/m K DIN 53752 Heat conductivity at 23 °C 0.19 W/m K DIN 52612-1 Water absorption at 23 °C/24h under 0.04 % EN ISO 62 Colour opaque - - Limiting oxygen index (LOI) 44 % ISO 4589-1 2
High purity properties Due to the excellent stability of the PVDF molecule, it is one of the very few materials that can be processed, welded and used under severe conditions without the use of additives (no pigments, thermostabilisers, processing aids or fillers are used in the GF piping grades). This makes it the material of choice for applications that demand a very high purity of the medium and have stringent requirements stipulating that the materials which come in contact with the medium do not leach contaminants. The PVDF raw materials used by GF fulfil the most rigid requirements of the semiconductor and pharmaceutical industry regarding high purity. In addition, products made of PVDF exhibit a very smooth surface. Leach out tests according to SEMI57 are done regularly for quality control. For <strong>SYGEF</strong> ® Plus products, only virgin raw material is used.
