Biopharmaceutical Industry

The biopharmaceutical industry requires materials that have excellent properties for the processing of specialty chemicals, high purity water, and resistance to various methods of sterilization required in the processing of pharmaceuticals. Select Kynar® grades meet the extreme demands and regulatory requirements of this growing industry.

Product Overview: Kynar® PVDF

For Biopharmaceutical applications requiring excellent resistance to acids, chlorine and bromine, Kynar® PVDF is a commonly used material of construction for process piping, pumps, tubing, tanks, filters and other fluid handling components. In addition to the chemical resistance of the process stream, Kynar® PVDF is also resistant to many common forms of sterilization such as ozonation, chemical bleaching, and steam-cleaning.

Easy Processing for a Complete Solution

The thermoplastic Kynar® PVDF family of resins is characterized by ease of welding and post forming. As Kynar® PVDF has a wide window of processing between the melting point and the onset of decomposition, it is commonly welded by several methods: butt fusion, socket fusion, electrofusion, bead and crevice free, hot gas welding, extrusion welding, ultra-sonic welding, and hot lamination. This ease of fabrication enables multiple piping system joining methods, construction of tanks and vessels, and specialty fluid handling components. In addition, Kynar® PVDF and Kynar Flex® PVDF give the designer the ability to confidently join rigid and flexible fluoropolymers in the same construction

 

 

Smooth Surface Finish

Select grades of Kynar® PVDF are carefuly designed with attention to molecular weight distribution and melt flow rate to allow the fabricators who injection mold and extrude to produce parts with very smooth surfaces. In the biopharmaceutical industry this feature is important as it leads to fewer crevices and pores that could harbor the growth of bacteria.
