HDC for PTFE Machining Service
Polytetrafluoroethylene or PTFE, also popularly known as Teflon, is a fluoropolymer that has wide applications across multiple industries. The main characteristics of the PTFE that make it as a great material for products are its resistance to chemicals, excellent thermal stability, low coefficient of friction and resistance to changes in light/UV radiations. Applications of PTFE machining range from coatings of non-stick frying pan top, to medical equipment and manufacturing of wiring connectors, insulators, etc. Here is why you should choose us for precision PTFE machining.
Why Choose Us
Available PTFE Materials
PTFE raisins have a continuous rating of 260 °C. Beyond this temperature, the physical properties begin to degrade. Although the physical properties are similar for most variants of the PTFE, however, the properties vary due to the different compositions of these different grades. PTFE machined parts are often chemically inert and thermally resistant over a large range of temperatures. In addition, PTFE displays a quality of high resistance and low coefficient of friction. The material has a tensile strength of 20-35 Mpa and a density between 2.13 – 2.23 g/cm3.
Here are a few common grades of PTFE :
Virgin Electrical Grade
The virgin electrical grade is extremely resistant to chemicals and has a low coefficient of friction. Furthermore, it resists temperature changes over a wide range. Since this grade is FDA-approved, it is widely used in the manufacturing of food-grade PTFE materials. Moreover, the virgin electrical grade is ideal for electrical connectors.
Reprocessed Mechanical Grade
The reprocessed mechanical grade PTFE is ideal for use in places where there are high temperatures. This grade of PTFE offers multiple benefits of mechanical and thermal resistance. Major applications of reprocessed mechanical grade include the manufacturing of bushes and bearings.
25% Glass Filled
Glass-filled fiber offers multiple benefits like hardness, better response to compression, and resistance to wear. Furthermore, this grade of PTFE machined parts is resistant to temperature changes and higher loads. Also, this is the most commonly used PTFE. Commonly used for manufacturing of valve parts.
Although not a standard grade of PTFE but there are many custom grades of PTFE that are available in the market. Custom grades of PTFE are created by varying the composition of Carbon, Graphite, or other additives. Each custom grade offers different benefits to varying degrees. Therefore, depending on your need the custom part can be manufactured.
FAQ About PTFE Machining Service
Is machining Teflon easy?
Due to the low friction coefficient and high thermal stability, it becomes easier to machine Teflon. These properties also prevent tool clogging and part deformation. So, CNC machining plastic parts is a feasible option for your plastic parts.
What Chemicals can PTFE resist?
PTFE is resistant to almost all chemicals. However, at higher temperatures, PTFE may experience reactions with certain types of Alkalis metals, fluorine, and chlorine trifluoride.
How to choose the right PTFE material for machining?
There are a lot of factors involved in the selection of the right Teflon type for your product. Some of the aspects that affect the material selection are a temperature of an area of application, mechanical stresses the part has to undergo, any turning or torsion loads to be experienced by the part, etc. Selecting the right material for the job is a complicated task. That is why we have a dedicated team of material specialists who know which grade of PTFE to choose in what application.
