Description
Overview
ULMAN T4152 is manufactured from a high-tensile-strength PTFE yarn. The selected additives combined with PTFE’s sliding characteristics improve heat dissipation, making the material suitable for high-speed pumps. The packing resists acids and alkalis, shows minimal shrinkage and stable volume, and its microporous structure retains lubricants for extended service life.
Application
Used where high temperatures, aggressive media or variable operating conditions require reliable sealing: pumps, mixers and valves in chemical, power, food, pharmaceutical, oil & refinery and general plant engineering.
Fields of application
Main use
Chemical industry (acids, alkalis, solvents); power and energy systems (hot water, steam, condensate); food and pharmaceutical industries where medium purity is required.
Materials
PTFE
Technical values
Pressure: 30 dyn. / 250 stat.
Temperature: -200 °C / +280 °C
Speed: up to 15 m/s
pH value: 0–14
