PCTFE is chemically similar to PTFE, and thus resistant to many corrosive chemicals, but is melt processable and can be injection molded, compression molded or extruded. It has an upper useful temperature rating of 400 °F (204 °C), but it also has value in cryogenic applications down to -400 °F (-200 °C). It can be a difficult material to work with, sometimes requiring annealing, and Micromold has all the needed expertise based on years of experience working with it. Micromold CNC machines PCTFE valve seats and other OEM parts for semiconductor manufacturing, as well as other process industries. As discussed in depth on our OEM page here, Micromold also routinely works with the following materials, and has extensive experience in machining and fabricating them alone or in combination:

• Acetal (Delrin®, Celcon®)	• PEEK	• PPS (Ryton®)
• Acrylic	• Polyamide-imide (Torlon®)	• PVC
• CPVC	• Polyimide (Vespel™)	• SP-Polyimide (Vespel®)
• Nylon	• Polyethylene	• UHMW Polyethylene
• PBI (Celazole®)	• Polypropylene

As you can see from the above discussion and examples, we not only apply those same machining skills to our standard and custom fluoropolymer-based products, but add a whole plethora of specialized understanding of these unique and valuable materials.
