Polytetrafluoroethylene (PTFE), traditionally known for its low coefficient of friction, thermal stability and superior chemical resistance, is widely used throughout the semiconductor, medical and chemical process industries.
Polytetrafluoroethylene (PTFE), traditionally known for its low coefficient of friction, thermal stability and superior chemical resistance, is widely used throughout the semiconductor, medical and chemical process industries. A new porous form of PTFE is now available with customer-specified pore sizes from 10 microns to 100 microns (classified with bubble-point measurements). The pores are evenly distributed, consistently sized and form an open-cell tortuous path throughout the PTFE. Moreover, the material can be machined; after being fully compressed and completely sintered, it can withstand conventional plastic machining methods without collapsing the pores or crumbling the edges. Intricate components and tight tolerances are achievable.
The company's porous PTFE offers a variety of benefits over traditional sponge PTFE, including excellent gas/liquid diffusion and filtration characteristics, a high degree of purity and enhanced physical integrity. Naturally hydrophobic, the material can be made hydrophilic for certain applications. A weldable form of the material, exhibiting much higher hardness, is also available.
The material has already attracted attention in the analytical sensor, chromatography, biomedical and semiconductor industries. Applications include solid phase extraction frits, fluidizing-bed plates, filter tips, gas sparging tubes and pneumatic mufflers/vents.
