MFA (sold under the trade name “Hyflon”) is a perfluoropolymer (totally fluorinated) and has a chemical structure similar to PFA. MFA exhibits the outstanding thermal behavior and chemical resistance found in PTFE, PFA and FEP. In addition, parts made with MFA have been shown to have smooth finished surfaces. This makes MFA a good candidate for the semiconductor, electronics and biologic applications where sanitary flow (fully swept flow – no dead spots) is required. MFA is reported to have better thermal stress crack resistance, higher thermal rating and superior mechanical and electrical properties versus FEP, at high temperatures.
Fluorotherm produces tubing of MFA in all industrial sizes, with standard wall thicknesses of 0.031”, 1mm, and 0.062”. Custom sizes are available upon request.
MFA has low haze values and transmittance of wavelengths in the visible and the UV bands of the spectrum.
