Low Density Extruded PTFE

Low density extruded PTFE below 0.9g/cm3 for high frequency – microwave – coaxial cable applications in data transfer, military and medical field.

• The low dielectric constant and low loss factor of low density extruded PTFE help to reduce the insertion loss of coaxial cables and improve the transmission rate.
• The good mechanical properties of low density extruded PTFE help achieve faster wrapping speed and improve production efficiency.
• Low density extruded PTFE has low density when used as cable wrapping, which helps to reduce the mass and volume of the cable.

 

Low Density Extruded PTFE How to process?

Low Density Extruded PTFE With an extremely high melting viscosity and a high melting point. This is due to its rigid polymer-chain structure. This, in turn makes extrusion and injection molding processing difficult. The similarity between processing technology and powder metallurgy is greater than that of traditional processing technology. sintering, pressing, stamping or paste extrusion, compression molding, or isoform forming, machining, hot stamping and extrusion on a special machine. Paste extrusion, before forming the preform, Low Density Extruded PTFE Mix with the hydrocarbons. This continuously will be the Low Density Extruded PTFE Make the pipe, belt and wire insulation layer. The hydrocarbons were evaporated before the parts were sintering.

Dispersion -- metal coating, coating, crushing, impregnation, film casting, fiber spinning. [Scope of operation (-270℃) -200℃ ~260℃ (280℃)] Low Density Extruded PTFE The characteristics of the products largely depend on the processing process.including: fineness sinter point tonnage In the Low Density Extruded PTFE For specific applications that are not fully applicable, other fluoropolymers are required. This prompted the search for mel-processed fluoropolymers and developing other members of the family.
