PTFE diaphragm sheet characteristics

  • excellent corrosion resistance: able to withstand most acids, alkalis, solvents and other corrosive media, to ensure long-term stable operation in complex chemical environments.
  • good high temperature resistance: can maintain stable performance in high temperature environment, will not be deformed or damaged due to temperature changes. Low coefficient of friction: has a very low coefficient of friction, making the pneumatic diaphragm valve smoother in the switching process, reducing energy loss and wear.
  • high elasticity and toughness: excellent elasticity and toughness, able to withstand certain pressure and impact, maintaining the integrity and stability of the diaphragm sheet

Uses

PTFE pneumatic diaphragm sheet is widely used in chemical, pharmaceutical, food and water treatment industries. In the chemical industry, it is often used to transport corrosive liquids and gases; in the pharmaceutical and food industries, its non-toxic and biocompatible characteristics make it an ideal isolation material; in the field of water treatment, PTFE pneumatic diaphragm sheet is used in filtration and separation operations to ensure the safety and purity of water quality.
