Introduce

  • Airtightness: The valve has a built-in sealing ring to ensure that the valve is airtight and intact
  • Polypropylene multi-function valve: reasonable valve design, good air tightness
  • Compatible with aluminum foil, Teflon, Tedla, PVDF sampling bags. Acid and alkali resistance
  • Polypropylene characteristics: chemical stability is very good, in addition to being corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to various other chemical reagents, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can soften polypropylene, swelling,
  • Applicable temperature range: -30 degrees Celsius to +100 degrees Celsius

Application

  • Valve closed: turn clockwise to the end;
  • Valve opening: from closed to open, the flow rate can be adjusted by one and a half circles according to needs;
  • There is a sampling hole on the top cover and a built-in silicone pad for needle sampling with high sampling accuracy. It is recommended to replace the silicone pad about 15 times.
  • The thickness of Teflon fep film is generally around 0.075mm-0.1mm. According to the inventory of each batch of warehouses, the thickness of Teflon is different, and the price of different thicknesses is also different.
  • The pvf gas sampling bag is a film of Tedlar gas sampling bag, the thickness is about 0.05mm, and the temperature resistance is about 150 degrees.
  • The thickness of PVDF film is 0.05mm-0.075mm, and the temperature resistance is about 150 degrees. The lead time depends on the stock in the warehouse, and the price varies with the thickness.

Equipped with PTFE valve

When using a PTFE valve, the knob is closed when it crosses the outlet, and the knob is parallel to the outlet when it is open. The temperature resistance of PTFE valves is about 200 degrees. Using PTFE valve, the temperature resistance of the whole bag is consistent with that of the film.

FAQ

What is polytetrafluoroethylene (PTFE)?

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. It is a white, waxy solid that is known for its exceptional nonstick properties, high chemical resistance, and low friction coefficient. PTFE is widely recognized by its brand name Teflon, which is a registered trademark of Chemours, a spin-off of DuPont.

What are the key properties and characteristics of PTFE?

PTFE possesses several unique properties that make it highly desirable for various applications. It has excellent chemical resistance, being virtually unaffected by most chemicals and solvents. PTFE is also non-reactive, making it suitable for use in harsh environments. It has a low coefficient of friction, providing excellent nonstick properties, and it retains its nonstick characteristics even at high temperatures. PTFE is also electrically insulating, with high dielectric strength, and has a wide temperature range of -200 to +260 degrees Celsius (-328 to +500 degrees Fahrenheit). Additionally, PTFE is biologically inert, making it suitable for use in medical and food-grade applications.

What are the applications of PTFE?

PTFE finds applications in a wide range of industries due to its unique properties. It is commonly used as a nonstick coating for cookware, such as frying pans and baking sheets. PTFE is also used as a lining material for pipes, tanks, and vessels that handle corrosive chemicals. Its low friction coefficient makes it suitable for bearings, seals, and gaskets in various mechanical systems. PTFE is used in electrical insulation, such as wire and cable coatings, and it is also employed in the manufacturing of electrical components, such as connectors and insulators. Additionally, PTFE is utilized in medical devices, such as catheters and surgical implants, due to its biocompatibility.

What are the advantages of using PTFE?

The use of PTFE offers several advantages in various applications. Its exceptional nonstick properties make it easy to clean and release materials, reducing the need for excessive lubrication or cleaning agents. PTFE's high chemical resistance ensures long-term durability and protection against corrosion. Its low friction coefficient reduces wear and tear, improving the lifespan of mechanical systems. PTFE's electrical insulation properties make it safe for use in electrical applications. Furthermore, its biocompatibility makes it suitable for medical and food-grade applications. PTFE is also highly stable at high temperatures, maintaining its properties without degradation. Overall, the advantages of PTFE include its nonstick nature, chemical resistance, low friction, electrical insulation, biocompatibility, and high temperature stability.

Are there any limitations or considerations when using PTFE?

While PTFE has many desirable properties, there are some limitations and considerations to keep in mind. PTFE has a relatively low mechanical strength compared to other engineering materials, so it may not be suitable for applications that require high load-bearing capabilities. It also has a relatively high coefficient of thermal expansion, which needs to be considered for dimensional stability in certain applications. PTFE has poor adhesion properties, making it difficult to bond or paint directly onto its surface. Pre-treatments or specialized adhesives may be required for proper adhesion. Additionally, PTFE is susceptible to damage from high-energy radiation, so it may not be suitable for applications in radiation-intensive environments. It is also important to consider the potential release of toxic fumes when PTFE is heated above its recommended temperature range.
