FEP/PFA/ETFE Heat Shrink Tubing

FEP HEAT SHRINK TUBING(Shrink Ratio: (1.3:1)&(1.6:1)&(2:1))

Product Description

Our FEP, PFA, and ETFE Heat Shrink Tubing is a family of high-performance fluoropolymer heat shrink products designed for demanding applications that require superior thermal resistance, chemical stability, electrical insulation, and mechanical protection. These materials are lightweight, transparent, and capable of withstanding a wide temperature range, making them ideal for use in harsh industrial, medical, and aerospace environments.

• FEP (Fluorinated Ethylene Propylene): Offers excellent low-temperature flexibility and optical clarity, making it perfect for visual inspection applications.

• PFA (Perfluoroalkoxy): Provides exceptional chemical resistance and long-term high-temperature performance, ideal for semiconductor and pharmaceutical processing.

• ETFE (Ethylene Tetrafluoroethylene): Known for superior mechanical strength, abrasion resistance, and radiation tolerance, making it suitable for heavy-duty and high-stress environments.

Available in multiple shrink ratios (1.3:1, 1.6:1, 2:1), these heat shrink tubes tightly conform to a variety of shapes and diameters, ensuring reliable sealing and protection for cables, wires, connectors, and equipment.

Detailed Features

1. Wide Operating Temperature Range

• Functional from -200°C to +200°C (short-term up to 260°C), making it suitable for both cryogenic and high-heat applications.

• PFA offers the highest thermal endurance, ideal for processes requiring continuous high-temperature exposure.

2. Excellent Chemical Resistance

• Nearly unaffected by strong acids, alkalis, solvents, and most corrosive chemicals.

• PFA is particularly suited for high-purity chemical environments due to its extremely low leach-out rates.

3. High Transparency

• FEP and PFA offer excellent optical clarity for visual inspection of internal cables, fluids, or connectors.

• Useful for monitoring critical systems without disassembly.

4. Dimensional & Mechanical Stability

• Retains shape and dimensions under thermal cycling and mechanical stress.

• ETFE provides superior tensile strength and impact resistance, protecting components in high-vibration or abrasion-prone environments.

5. Low Friction & Non-Stick Surface

• Smooth surface resists adhesion and buildup of contaminants, making cleaning and maintenance easier.

• Ideal for roller coatings, wiring harnesses, and dynamic equipment.

6. Regulatory Compliance

• Meets RoHS, REACH, and FDA standards, suitable for use in food contact and medical device applications.

• GD-FEP has passed UL/C-UL VW-1 flame resistance certification, ensuring fire safety compliance.

Key Advantages

• Reliable Protection: Chemical inertness and low permeability ensure long-term defense against corrosion, moisture, and environmental stress.

• Ease of Installation: Controlled shrink ratios guarantee predictable, uniform shrinkage and a tight, professional fit.

• Long-Term Durability: Exceptional thermal stability, UV resistance, and crack resistance minimize aging and reduce maintenance costs.

• Application Versatility: Covers a wide range of industries — electronics, aerospace, chemical processing, food manufacturing, and medical equipment.

• Global Compliance: Pre-certified for RoHS, REACH, FDA, and flame resistance, simplifying international approvals and product certification processes.
  
  

Application Fields

Usage Guidelines / Precautions

• Pre-measure tubing length before installation to ensure proper coverage.

• Use a controlled heat source (e.g., hot air gun or oven) to ensure even shrinkage and avoid overheating.

• Avoid exposure to open flame to prevent surface degradation.

• Store in a cool, dry place away from direct sunlight to maintain material properties.

FAQ

Q1: What shrink ratios are available?
A: We offer 1.3:1, 1.6:1, and 2:1 shrink ratios, suitable for a range of component sizes and shapes.

Q2: Can this tubing be used in high-temperature applications?
A: Yes. FEP can operate up to 200°C (260°C short term), while PFA supports continuous use up to 260°C, making it suitable for semiconductor, pharmaceutical, and thermal cycling processes.

Q3: Is the tubing food-safe?
A: Yes, both FEP and PFA comply with FDA requirements, making them suitable for food contact and cleanroom applications.

Q4: How does ETFE differ from FEP/PFA?
A: ETFE offers higher mechanical strength, abrasion resistance, and radiation tolerance, making it ideal for high-stress or high-radiation environments such as aerospace and nuclear applications.

Q5: How should the tubing be heated for shrinking?
A: Use a hot air gun or oven at controlled temperatures to achieve uniform shrinkage. Avoid direct flame contact to prevent surface damage.
