Product specification

MFA is a newly developed fluorinated plastic, highly resistant and suitable for extreme mechanical and thermal loads

Lowest embrittlement at temperature load

High resistance to weathering

Very good mechanical stability from lowest temperatures up to +250 °C

Volume resistivity, dielectric constant and loss factor independently of the temperature

Outstanding thermal stability (weight loss <0.3 % at +380 °C, 50 min. in air)

Non-oxidizing
