MT-FEP FEP Heat Shrink Tubing Applications • Process aid for reflowing catheter shafts • Process aid for joint bonding PROFILE • Shrink ratio < _ 1.6:1 • Full recovery at 210°C (410°F) minimum • Tight longitudinal change control as low as ± 2% • Manufactured to ISO 10993 standards • Custom sizing, finishing options available • Translucent for high optical clarity • Color blending option available ABOUT • MT-FEP is a fluorinated ethylene propylene (FEP) heat shrink tubing. FEP offers excellent consistency, high dielectric strength and is chemically inert. MT-FEP is lubricious and semi-rigid with shrink ratios up to 2:1*. FEP is the industry gold standard for reflowing catheter shafts and bonding joints. • For our MT-FEP, we can control longitudinal growth ± 2% ensuring consistency on lot-to-lot, reducing waste and cost. *Upper limit on select applications.
