Here is some reference data on the non-stick, water-repellent, heat-resistant, and slippery (low friction) properties of fluororesin.
■Non-stickiness: It refers to the property of being easily released from strongly adhesive substances, either not adhering at all or having a tendency to adhere less. ■Water repellency: It refers to the property of repelling liquids and not getting wet when they come into contact with the surface. 【Reference data for non-stickiness and water repellency】 ■Contact angle of water (°) PTFE ... 114 PFA ... 105-110 FEP ... 115 ETFE ... 96 ■Contact angle of n-HD (°) PTFE ... 34-45 PFA ... >45 FEP ... 41-45 ETFE ... 28 ■Surface free energy of solids (dyne/cm) PTFE ... 18.5 PFA ... 17.8 FEP ... 17.8 ETFE ... 22.1 ■Low friction: It has a slippery feel and a low coefficient of friction, providing excellent lubricity. 【Reference data for low friction】 ■Static friction coefficient (μ) PTFE ... 0.02-0.04 PFA ... 0.04-0.05 FEP ... 0.05-0.06 ETFE ... 0.07-0.08 *The values are general characteristics and are not guaranteed. *For more details, please contact us.
