Heat shrink fabric refers to thermoplastic tubing that contracts radially upon heating, creating a tight protective covering for cables and wires. This material is engineered to provide insulation, mechanical protection, and environmental sealing in modern electronic, industrial, and aerospace applications. Its importance lies in enhancing system reliability through strain relief, moisture resistance, and dielectric insulation.
| Type | Functional Features | Application Examples |
|---|---|---|
| Standard Polyolefin | General-purpose insulation, 2:1 shrink ratio, UV resistance | Consumer electronics wiring |
| Double-Wall Adhesive | Internal adhesive layer for sealing, 3:1 shrink ratio | Military connectors |
| PVC Heat Shrink | Flexible, flame-retardant, cost-effective | Automotive harnesses |
| PTFE/FEP Tubing | High-temperature resistance (200 C+), chemical inertness | Aerospace sensor cables |
| Expandable Braided Sleeving | Recoverable diameter adjustment, abrasion resistance | Industrial robotics |
Typical construction includes: - Base Material: Cross-linked polyolefin, PVC, or fluoropolymers - Adhesive Layer: Thermoplastic elastomer (for sealing variants) - Additives: UV stabilizers, flame retardants, colorants - Wall Structure: Single-wall (basic protection) or double-wall (with adhesive lining)
| Parameter | Typical Range | Importance |
|---|---|---|
| Shrink Temperature | 85-200 C | Determines application compatibility |
| Shrink Ratio | 2:1 to 6:1 | Affects size flexibility |
| Dielectric Strength | 15-50 kV/mm | Ensures electrical safety |
| Operating Temperature | -55 C to +150 C | Defines environmental limits |
| Adhesion Strength | 0.5-4.0 N/mm | Sealing performance indicator |
| Manufacturer | Representative Product | Unique Features |
|---|---|---|
