PASTE EXTRUDED PRODUCTS

Products manufactured by Paste extrusion technology enables Vimal Polymers to broaden the PTFE product line with additional designs and profiles. In this manufacturing method, very close process control of the PTFE grain size range is maintained. For the paste extrusion process, the extrudable PTFE fine powders are blended with a volatile lubricant (hydrocarbon) for preparing the paste, which is then pre-pressed and filled in a PTFE paste extruder. The preform paste is compressed in a cold or in the preheated stage through a die. The part obtained is separated from the lubricant, followed by the sintering process. For the paste extrusion process, the production is done in batch quantities. We can manufacture the paste extruded products according to the applications with required chemical, physical and mechanical properties.
