3M 7000048534 Polyester Film Tape 1 in 72 Yd Series 8403

Product Description

The 3M 7000048534 is a green polyester film tape from the 3M Series 8403 line, built for industrial and trade applications that demand reliable performance across a wide temperature range. It uses a silicone adhesive system rated from -60 degrees F to 425 degrees F, making it suitable for high-heat environments. The tape measures 1 inch wide and 72 yards long, with a film thickness of 2.4 mil and a tensile strength of 46 pounds per inch. Licensed tradespeople and maintenance technicians working in electrical, HVAC, and manufacturing environments install this tape where standard acrylic or rubber-adhesive tapes would fail under thermal stress.

This tape is designed for holding, paint masking, protecting, and splicing applications. It performs well in both industrial production environments and field service scenarios where components must be masked or secured during high-temperature processes such as powder coating, wave soldering, or thermal cycling. Its polyester film backing resists tearing and maintains dimensional stability under load, which makes it a dependable choice for precision masking tasks where clean removal and sharp paint lines are required.

Key Features

• Silicone adhesive rated from -60 degrees F to 425 degrees F for high-heat and cryogenic applications
• 2.4 mil polyester film backing with 46 lb per inch tensile strength for tear resistance
• Green color for easy identification during masking and protection tasks
• Suitable for holding, paint masking, protecting, and splicing applications
• 72-yard roll length reduces changeover frequency on production or service tasks

Compatibility

Designed as an OEM-style industrial tape replacement for applications requiring silicone adhesive and polyester film construction in high-temperature service environments.

Installation Notes

Surface preparation is critical before application — ensure surfaces are clean, dry, and free of oils or contaminants for maximum adhesion. When using for paint masking or protection, apply firm pressure along the tape edge to prevent bleed-through. Remove tape while the surface is still warm if used in high-temperature bake or cure cycles to reduce adhesive residue. Follow applicable facility safety procedures when working near heated equipment or during thermal process operations.
