Excellent Corrosion Resistance
FEP material can withstand almost all strong acids (e.g., concentrated sulfuric acid, nitric acid), strong alkalis, organic solvents, and oxidants. Its chemical stability is second only to PTFE (polytetrafluoroethylene), ensuring the purity of conveyed media and long service life of the tubing.
Outstanding Resistance to High and Low Temperatures
It can operate continuously within a wide temperature range from -80°C to +200°C. It can withstand high-temperature sterilization while remaining flexible at low temperatures without becoming brittle.
High Transparency & Non-Stick Properties
The tube wall is transparent, allowing for real-time observation of the fluid's status, color, and flow rate inside the tube. Its smooth surface has excellent non-stick properties, preventing media residue, facilitating easy cleaning, and effectively avoiding cross-contamination.
Superior Mechanical Protection
The outer spring sleeve (typically made of PVC or stainless steel) provides excellent resistance to compression, stretching, and abrasion for the inner tube. It protects against damage caused by bending, crushing, or vacuum collapse, significantly enhancing the mechanical strength of the assembly.
High Purity & Safety
FEP itself is non-toxic, odorless, complies with food and pharmaceutical contact safety standards, and is physiologically inert, making it suitable for biopharmaceutical and food industries. Furthermore, the material is flame retardant for safe use.
Analytical Instruments: Widely used in chemical analyzers and medical testing equipment to transfer reagents, samples, and solvents.
Semiconductors & Photovoltaics: Used in ultrapure water delivery and wet etching processes to ensure high-purity, contamination-free transfer of chemicals.
Biopharmaceuticals: Used for transferring materials like culture media, buffers, and pharmaceutical solutions, capable of withstanding sterilization processes.
Chemical Processing: Safely conveys various corrosive chemicals; the spring structure adapts well to complex equipment layouts.
Environmental Protection & Water Treatment: Used for sampling, chemical dosing, etc., offering corrosion resistance and durability.
