Teflon-impregnated carbonized fiber is a highly resilient gland packing made by combining Teflon and special lubricating oil with carbon fiber, using a special angle knitting method for impregnation.
Daiko's Grand Packing 'D4101-4106' for Pumps and Valves 'D4101' is a highly resilient grand packing made using a special braiding method that combines and impregnates carbon fibers with Teflon (PTFE) and special lubricating oil. Grand packing is a sealing gasket widely used in static, rotating, and reciprocating shaft sealing locations such as valves, pumps, manholes, and furnace openings. In addition, we offer products such as 'D-4102', which is made by impregnating pure Teflon fibers with Teflon dispersion, and 'D-4103', which is made by impregnating special carbon fiber with Teflon dispersion and braiding it. 【Performance】 ■ Operating temperature range: 200℃ ■ Pressure: 1MPa ■ Shaft peripheral speed: 25m/Sec ■ PV value: 10MPa·m/sec ■ pH value: 2-12 *For more details, please refer to the PDF document or feel free to contact us.
