I. Introduction1.1 Special Requirements for Materials in High-Temperature EnvironmentsIn high-temperature environments, materials must meet stringent performance criteria. Thermal resistance is paramount, ensuring stability without melting, softening, or decomposition. Mechanical strength is crucial to withstand creep and stress relaxation under prolonged thermal loads. Electrical insulation must maintain high resistance to prevent leakage risks as temperature rises. Chemical stability is essential to resist corrosion from acids, solvents, or other chemicals commonly present in industrial processes.
1.2 Importance of Polyimide Tape in IndustriesPolyimide tape plays a pivotal role across industries. In electronics, it secures components and protects against thermal and chemical degradation, ensuring device reliability. In electrical engineering, it provides insulation for motors, preventing shorts and extending equipment lifespan. Aerospace applications leverage its thermal and chemical resistance for critical components in aircraft and rockets. Polyimide tape’s versatility and durability make it indispensable in diverse industrial sectors.
II. Performance Metrics Comparison2.1 Key Performance ParametersKey evaluation metrics include:
●

III. Cost-Benefit Analysis3.1 Procurement Costs
● 
Polyimide Tape: 15–15–40/roll (dependent on thickness and width).
● 
PTFE Tape: 5–5–20/roll (lower cost but limited lifespan).
● 
Silicone Tape: 3–3–15/roll (economical but prone to degradation).
● 
Ceramic Tape: $50+/roll (highest upfront cost due to material complexity).
3.2 Lifecycle and Maintenance
● 
Polyimide Tape: Longevity (5+ years), minimal maintenance (low replacement frequency).
● 
PTFE Tape: Shorter lifespan (1–2 years), frequent inspections and replacements.
● 
Silicone Tape: Moderate durability (2–3 years), requires periodic replacements.
● 
Ceramic Tape: High durability but brittle, prone to breakage during handling.
3.3 Total Cost of Ownership (TCO)TCO = (Procurement Cost) + (Maintenance Cost) + (Replacement Cost) + (Downtime Costs).Polyimide tape’s higher upfront cost is offset by longevity, reducing TCO over 5–10 years. PTFE and silicone tapes’ lower acquisition prices are offset by frequent replacements and downtime, resulting in higher TCO. Ceramic tape’s high costs and fragility lead to the highest long-term expenses.
