PTFE parts CNC machining manufacturer Creatingway

PTFE is commonly called “non-stick coating or easy cleaning material” in our life, so it has resolve some problems in chemical, petroleum, pharmaceutical and other fields. And for now, as one of special engineering plastics, which has been known and applied by more and more people.

As one professional CNC Machining service material, Creatingway not only can machining common engineering plastic parts, but also machining special plastic parts. Such as: PTFE,Nylon, plexiglass parts etc . Today, we will further discuss “PTFE cnc machining parts”.

What’s the characters for PTFE parts CNC Machining?

PTFE has the characteristics of anti-acid, alkali resistance and various organic solvents, and is hardly soluble in all solvents. And PTFE also has high temperature resistance, low friction coefficient, so it can be used as a lubricant and also become an ideal coating for easy cleaning water pipe inner layer.

Advantages& Disadvantages of PTFE parts CNC Machining

Advantage of PTFE parts CNC Machining

High temperature resistance

It can continue to operating in the 250℃work environment

Low temperature resistance

Good mechanical performance; it can keep 5% elongation when the temperature drops to 196 ℃.

Corrosion resistance

For most chemicals and solvents, it shows the inertia, strong acid, strong alkali, water and various organic solvents.

Weather resistance

It has own the best aging life in plastic.

Good lubrication

The lowest of friction coefficient in solid materials

No adhesiveness

Its surface tension is the smallest in a solid material and does not adhere to any material

Non-hazardous

It has stronger the physiological inertia, the artificial blood vessel and viscera long implantation without adverse reactions.

Electrical insulating property–It can resist 1500 volts of high voltage

Maybe you know more advantages of PTFE cnc machining parts, but it also has a certain deficiencies.

PTFE has” cold fow”.

PTFE is easily deformation when it continues to work under the continuous load, which brings certain limitations to its application. When PTFE is used as a gasket for sealing, the bolts will be screwed tightly to exceed the specified compression stress, the gasket will be compressed by a “cold flow”.

2, Due to the PTFE part has “No adhesiveness so that it will bring certain limitations on the industrial application.

3, PTFE linear expansion coefficient is 10 ~ 20 times of steel, and bigger than most plastics, so its linear expansion coefficient will be easily changed by temperature.
