Characteristic
ETFE is a synthetic polymer formed by copolymerization of ethylene and tetrafluoroethylene, with a specific gravity of 1.7g/cm ³ and a molding temperature of 300-330 ℃. Its core features include:
High strength: The tensile strength reaches 50MPa (nearly twice that of PTFE), the impact resistance is outstanding, and the elongation rate is 100-300%.
Weather resistance: Long term use temperature -80 ℃~220 ℃, can withstand extreme weather conditions (UV, high temperature, low temperature) and has stable performance.
Chemical inertness: Resistant to acid, alkali, and most solvents, second only to PTFE and superior to PVDF.
Transparency: The film has a transparency of up to 95% and does not block ultraviolet rays.
Application Area
Architectural membrane structure: As a "soft glass" used in large-span buildings such as sports venues (such as Beijing Water Cube) and exhibition centers, its advantages include lightweight (0.15-0.35kg/m ²), self-cleaning, and a service life of over 25 years.
Industrial anti-corrosion: used for chemical equipment lining, cable insulation layer (especially for atomic reactor cables), due to its adhesion to metals and negative pressure resistance characteristics.
Medical device: Complies with biocompatibility standards and can be used for implanting device components.
