HTS-FEP-1500 Fluoropolymer Heat Shrink Tube, 2:1 Ratio, 1.6mm–19.1mm ID, FEP, 200°C Rated, FDA Compliant

Product Overview

The HTS-FEP-1500 Fluoropolymer Heat Shrink Tube is a premium-grade, high-performance insulation solution engineered for extreme thermal and chemical environments. Designed with fluorinated ethylene propylene (FEP) material, this FEP heat shrink tube delivers exceptional resistance to acids, solvents, UV radiation, and plasma etching—making it ideal for aerospace, semiconductor, medical device, and high-reliability electronics applications. With a precise 2:1 shrink ratio and continuous operating capability up to 200°C, it ensures tight, void-free coverage over irregular geometries and sensitive components. As an FDA compliant product, HTS-FEP-1500 meets stringent regulatory requirements for biocompatibility and extractables—critical for sterilizable assemblies and cleanroom-compatible wiring systems.

This high temp shrink tubing combines ultra-low coefficient of friction, near-zero moisture absorption (<0.01%), and outstanding dielectric strength (>30 kV/mm), enabling reliable performance in vacuum, cryogenic, and high-frequency signal environments. Its consistent wall thickness and controlled shrink behavior support automated assembly processes and IPC-A-620-compliant harness manufacturing.

Applications

The HTS-FEP-1500 is widely deployed across mission-critical sectors requiring 200C heat shrink reliability: wire harness insulation in jet engines and avionics; sensor lead protection in semiconductor process tools; sterile cable bundling in Class 7/8 cleanrooms; coaxial and RF connector sealing; and FDA-regulated diagnostic equipment cabling. As the definitive HTS-FEP-1500 solution, it replaces PTFE tapes and silicone sleeves where precision shrink-fit, long-term stability, and regulatory traceability are non-negotiable.
