Masking tape, high temperature resistant, 3M 5413 Premium, base PI 70μm, amber, 33m

The 3M™ 5413 Premium is a high-performance, amber-colored polyimide (PI) tape engineered for extreme thermal environments and precision masking. Featuring a robust 70μm total thickness (with a heavy-duty polyimide base), it provides superior mechanical strength and electrical insulation compared to standard “Econom” versions.

Technical Specifications

• Model: 3M™ 5413 (Premium Grade)
• Backing Material: Polyimide (PI) Film (Dupont™ Kapton® equivalent)
• Total Thickness: 70μm (2.7 mil)
• Adhesive Type: Silicone (Pressure Sensitive)
• Color: Transparent Amber
• Standard Roll Length: 33 meters (36 yards)
• Operating Temperature: -73°C to 260°C (-100°F to 500°F)
• Short-term Resistance: Can withstand spikes up to 315°C (600°F)

Key Performance Attributes

• High-Caliber Insulation: The 70μm profile offers exceptional dielectric strength, making it ideal for electrical components that generate significant heat.
• Dimensional Stability: Unlike thinner tapes, the premium PI base does not soften or shrink at high temperatures, ensuring the masking line remains perfectly intact.
• Minimal Adhesive Transfer: The high-grade silicone adhesive is designed for ultra-clean removal, leaving no residue even after multiple heating cycles or chemical exposure.
• Flame & Chemical Resistance: Inherently flame retardant and resistant to chemical solvents, making it suitable for aerospace and chemical processing applications.

Primary Applications

• PCB Manufacturing: Protecting gold fingers during wave soldering and solder reflow processes where precision and heat resistance are non-negotiable.
• Aerospace Engineering: Used for thermal insulation and masking in environments where weight and high-heat performance are critical.
• High-Heat Powder Coating: Masking complex geometries that require a thicker, more durable tape to withstand sandblasting or high-temp curing.
• Electric Vehicle (EV) Batteries: Insulation and bundling of cells where high thermal stability is required for safety.
