3M 7000048439 Polyethylene Tape 483 White 1in X 36yd

Product Description

The 3M 7000048439 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 conformability, solvent resistance, and reliable adhesion across a wide temperature range. The tape maintains flexibility down to -20 degrees F, making it suitable for cold-environment service. Low sulfur and halogen content make it appropriate for sensitive electronic and industrial environments. This tape is commonly handled by electricians, electronics technicians, and industrial maintenance professionals.

This tape is used across a range of trade and industrial applications including general container sealing, electroplating masking, printed circuit board masking, silicone chip holding, decorative banding, safety marking, and color coding. Its conformable backing allows it to follow irregular surfaces without lifting or tearing. The combination of chemical resistance and low contaminant content makes it a dependable choice for both light industrial and electronics assembly environments.

Key Features

• 5.3 mil polyethylene backing provides durable, conformable coverage
• Rubber adhesive delivers consistent bond on a variety of surfaces
• Remains flexible down to -20 degrees F for cold-environment use
• Low sulfur and halogen content suitable for electronics masking applications
• Good solvent resistance for plating and chemical process environments
• White color supports safety marking and color-coding applications

Compatibility

Designed for general-purpose masking, sealing, and color-coding tasks in light industrial, electronics assembly, and electroplating environments where a conformable, low-contaminant tape is required.

Installation Notes

Application should be performed on clean, dry surfaces free of oils, dust, and debris to ensure proper adhesion. In electroplating or chemical process environments, verify that the tape edges are firmly sealed to prevent solution migration beneath the backing. Remove the tape carefully after use to avoid residue transfer, particularly on sensitive electronic components or finished surfaces.
