Mochitek peelable FEP heat shrink tubing is a high-performance insulation and protective material that plays critical roles in medical catheters, guidewire assemblies, and precision instruments due to its unique tearable design and exceptional physicochemical properties. Currently, there are two main peelable technologies in the market: traditional pre-scored processing and innovative material formulation. Our company employs advanced proprietary material formulation technology by adding specific components to FEP raw materials, enabling the tubing to be easily torn without pre-scoring – particularly suitable for precision applications like catheter body reinforcement, component joining, guidewire tip reinforcement, and coating masking.
Our specially formulated FEP features:
✓ Pre-scoring unnecessary: Material modification enables easy tearing while avoiding strength reduction caused by traditional scoring
✓ High temperature resistance: -200°C to +200℃ operational range
✓ Chemical inertness: Resists acids, alkalis, solvents, and corrosive media
✓ Superior electrical insulation: High dielectric strength for high-frequency circuits
✓ Shrink ratio: Up to 2:1 shrinkage ratio
Technology Comparison:
| Feature | Traditional Pre-scored | Our Special Formulation |
| Tearing Method | Along pre-cut scores | Simply notch any cross-section to initiate easy tearing |
| Mechanical Strength | Weakened at score lines | Uniform strength throughout |
| Sealing Integrity | Potential leakage risks | Complete seal without leakage |
| Manufacturing | Additional processing steps | Direct material modification |
