Thermal Properties: ETFE has a melting temperature of 267oC, while the melting point for PTFE is 327 o The only similarity is that both materials tend to soften when they are placed in lower. 009 14 220–240 40 300 800 1. 6 0. 6 Hytrel® 4056 37 64 NY NY 26 500 152 -50 1. 65: Thermal Expansion, µm/m-K: 95: 110 to 120: Electrical Properties. After time–temperature superposition, shifted shear viscosity, extensional. 7 Low melting ETFE grade with improved stress crack resistanceETFE in building design . 92% after 1. Other characteristics of Tefzel™ ETFE resins include: Low wear factor (1/10 of reinforced nylon) High-impact strength and dimensional stability; Heat resistance with a rating for temperatures up to 150 °C (302 °F) based. Four planar zigzag chains are packed in the unit cell. 57 A, b = 11. 4 D1894 KEY FEATURES ETHYLENE TETRAFLUOROETHYLENE (ETFE) TYPICAL PROPERTY VALUES DESCRIPTION Filler. Figure 21. PFA has similar properties to FEP but can be used at working temperatures up to +260°C while remaining melt-processable, thanks to a lower melt viscosity than PTFE. °C1 Brittleness Temp. Custom Coating, Dip-Spin Coating. Ethylene tetrafluoroethylene (ETFE) is a polymer with a high melting temperature threshold, excellent radiation, electrical and chemical resistance properties. area factor, m2/kg 40 20 10 4 Availability Type LZ - ETFE, general-purpose X X X X Type CLZ - ETFE, one side cementable — X X X the structural stability of ethylene tetrafluoroethylene (ETFE), by mixing this polymer matrix with polyoxides. At the end of the test, the die and barrel are cleaned. The drawback of this technique is that there are a limited number of pharmaceutical agents and no biologically derived agents that can withstand the temperature and stress of the melt extrusion process with retained biological function. 5 25 50 125 Approx.
