In modern industry and scientific research, fluid transmission systems place increasingly higher demands on material performance. Especially in applications handling corrosive media, high-temperature and high-pressure environments, or requiring extremely high cleanliness, traditional rubber or plastic hoses often fall short.
Learn more about the structure and materials of Fluorine Filled Hoses.
Fluorine Filled Hoses, as the name suggests, are flexible pipes with a fluoropolymer as the main inner layer material, typically combined with a reinforcing layer and an outer protective layer. Their core advantage stems from the fluoroplastics used, the most common being polytetrafluoroethylene (PTFE), also known as Teflon.
Inner Layer (Core): Made of fluoropolymers such as PTFE, PFA, and FEP. These materials possess excellent chemical inertness, high-temperature resistance, and a low coefficient of friction.
Fillers: To further enhance performance, PTFE hoses sometimes incorporate specific additives through a "filling" process, such as glass fiber, carbon, graphite, or stainless steel powder. These fillers are designed to improve the hose's abrasion resistance, creep resistance, and pressure resistance.
Reinforcing Layer (Braided Layer): Typically braided from high-strength stainless steel wire (such as 304 or 316), providing the hose with the necessary mechanical strength and pressure resistance to withstand high-pressure environments.
Outer Layer (Sheath): Provides additional protection against environmental abrasion, chemical splashes, or UV radiation.

Fluoroplastic hoses maintain stable performance over an extremely wide temperature range. For example, PTFE can operate continuously at temperatures up to 260 degrees Celsius and remains flexible even at extremely low temperatures (such as liquid nitrogen), making it suitable for aerospace and cryogenic engineering.
PTFE has an extremely low coefficient of friction, which not only improves fluid transfer efficiency but also makes it non-stick. For applications with high-viscosity fluids or requiring high cleanliness (such as the pharmaceutical and semiconductor industries), this property effectively prevents contaminant residue.
Through external stainless steel braiding and internal filler, fluoropolymer-filled hoses exhibit excellent pressure resistance. The addition of filler significantly reduces "cold flow" or creep phenomena in PTFE under sustained pressure and high temperatures, thus ensuring long-term stable system operation.
Due to their versatility, fluoropolymer-filled hoses are widely used in the following key industries:
When selecting Fluorine Filled Hoses, the following key factors need to be considered:
Fluorine Filled Hoses represent the pinnacle of high-performance fluid transport technology.
