3M 7100003104 Bumpon SJ5908 Black Rollstock 4.5in X 36yd

Product Description

The 3M 7100003104 is a self-adhesive rubber bumper rollstock sold under the Bumpon SJ5908 product line. It ships in a continuous roll format measuring 4.5 inches wide by 36 yards long, making it well-suited for high-volume die-cutting operations where custom shapes and consistent thickness are required. The pressure-sensitive adhesive backing bonds to most clean, dry surfaces without tools or fasteners. Black in color, this rollstock is used to fabricate feet, stops, spacers, and vibration-dampening pads across a wide range of industrial and commercial applications. It weighs 21.5 pounds per roll.

This rollstock is used in manufacturing, assembly, and field-service environments where custom-cut bumpers are needed in quantity. Die shops and fabricators convert it into finished pads to spec. It also sees use in HVAC, electrical, and equipment-installation contexts where technicians need to prevent surface contact, reduce vibration transfer, or protect finished panels and enclosures. The roll format reduces waste compared to pre-cut sheet stock when a specific footprint is required.

Key Features

• Continuous roll format supports die-cutting into custom shapes and sizes
• Pressure-sensitive adhesive backing bonds without additional fasteners or adhesives
• 4.5 inches wide by 36 yards long for high-yield conversion
• Black rubber construction suited for feet, stops, and spacers
• Consistent thickness throughout the roll for repeatable die-cut results

Compatibility

Designed as a general-purpose self-adhesive rubber bumper rollstock for use wherever custom-cut feet, stops, or spacers are required on equipment, panels, enclosures, or assemblies.

Installation Notes

Surface preparation is critical before application — clean and degrease the mounting surface thoroughly before pressing the adhesive side down. A licensed technician or skilled assembler should perform die-cutting operations using appropriate cutting tools and safety equipment. When used in electrical or HVAC enclosure applications, ensure the bumper material does not obstruct ventilation openings or interfere with code-required clearances. Apply firm, even pressure across the full bonded area to ensure adhesive contact.
