FEP Lined LDPE Tubing is a composite pipe with a dual-layer structure, consisting of an inner layer of FEP (fluorinated ethylene propylene copolymer) and an outer layer of LDPE (low-density polyethylene). This composite structure combines the advantages of both FEP and LDPE, making it widely used in applications requiring corrosion resistance, cleanliness, and cost control.
FEP-lined LDPE pipe Structure
FEP Lining Layer: Features excellent chemical stability, high-temperature resistance, and anti-adhesion properties, suitable for conveying corrosive, pure, or high-purity media.
LDPE Outer Layer: Offers good flexibility and mechanical strength, protecting the inner layer while reducing overall costs.
LDPE Tubing with FEP Liner Advantages and Features
Strong Chemical Corrosion Resistance
The FEP lining can resist corrosion from most acids, alkalis, and organic solvents, making it suitable for transporting or contacting corrosive chemical media.
Excellent high-temperature performance
FEP can withstand temperatures up to 200°C, meeting the requirements for fluid transportation in medium to high-temperature environments.
Good hygiene and safety
FEP is an inert material, compliant with FDA, USP Class VI, and other food and medical standards, suitable for clean or sterile transportation environments.
Smooth inner wall with anti-adhesion properties
The FEP inner layer has an extremely low friction coefficient, making it resistant to the accumulation of impurities or microorganisms, and facilitating cleaning and fluid control.
Cost-optimized
The FEP lining combined with an LDPE outer tube structure balances performance and cost, offering greater economic efficiency compared to pure FEP tubes.
Excellent flexibility and pressure resistance
The LDPE outer layer provides adequate mechanical strength and flexibility, facilitating installation and bending.
