3M 7000048440 Polyethylene Tape 483 White 2in X 36yd

Product Description

The 3M 7000048440 is a white polyethylene tape with a 5.3 mil (0.13 mm) polyethylene backing and a rubber-based adhesive. It is engineered for applications that demand low sulfur and halogen content, making it suitable for electroplating masking and printed circuit board work where ionic contamination is a concern. The tape is conformable, offers good solvent resistance, and remains flexible down to -20 degrees F. It is sold in a 2-inch-wide by 36-yard roll. Technicians and assembly professionals working in electronics, plating, and general industrial environments reach for this tape when they need a durable, chemically tolerant masking or sealing solution.

This tape is used across a range of light industrial and electronics applications. Common uses include general container sealing, electroplating tank masking, printed circuit board masking, and silicone chip holding during processing. It also sees use in decorative applications, safety marking, and color coding on equipment and assemblies. Its conformability makes it effective on irregular surfaces where a rigid tape would lift or gap.

Key Features

• 5.3 mil polyethylene backing provides durable, flexible coverage
• Rubber adhesive with low sulfur and low halogen content for electronics-safe masking
• Remains flexible at temperatures as low as -20 degrees F
• Good solvent resistance for use around plating chemicals and cleaning agents
• Conformable construction adapts to irregular or contoured surfaces
• Suitable for color coding, safety marking, and decorative applications

Compatibility

Designed for use in electroplating masking, printed circuit board masking, silicone chip holding, general container sealing, and color-coding applications in light industrial and electronics service environments.

Installation Notes

Surface should be clean, dry, and free of oils or contaminants before application to ensure proper adhesion. Apply with firm, even pressure across the full tape width to prevent lifting at edges. When using for electroplating or chemical masking, confirm the tape edges are fully sealed to prevent solution wicking. Remove the tape carefully after processing to avoid substrate damage, pulling back at a low angle.
