Avery Dennison™ FT 7387 – Differential Semi-Removable Acrylic/ Permanent Rubber Tape for Polishing Applications
Product Overview:
Avery Dennison™ FT 7387 is a high-performance double-coated tape engineered with a differential adhesive system, combining a semi-removable acrylic adhesive on one side and a permanent rubber adhesive on the other. Designed specifically for polishing pad applications, this tape provides excellent initial adhesion to various polishing materials while allowing clean removability where required. Its transparent polyester carrier ensures dimensional stability, while the balanced medium release liner enables efficient handling and matrix strippability at the point of application.
Key Features
Differential Adhesive System: Semi-removable acrylic (MS) on one side, permanent rubber (LS) on the other.
Polyester Carrier: 12 µm transparent polyester film provides strength and flexibility.
Balanced Medium Release Liner: White glassine liner allows easy removal and application.
Matrix Strippable Design: Enables efficient liner removal during assembly.
Benefits
High Initial Tack and Shear: Ensures immediate adhesion to polishing materials and other substrates.
Excellent Creep Resistance: Maintains bond integrity during use while allowing clean removal at MS.
Improved Die-Cutting Performance: Reinforces polishing material and facilitates precise conversions.
Dimensional Stability: Polyester carrier ensures consistent performance during processing.
Easy Application: Designed for smooth liner removal and accurate positioning.

Application Techniques
Surfaces must be clean, dry, and free of grease or oil prior to application.
Bond strength depends on adhesive-to-surface contact, pressure, and dwell time.
Performance may vary depending on surface type, rigidity, and temperature.
Storage and Shelf Life
Store in original packaging at 64–72°F (18–22°C) and 30–70% relative humidity, out of direct sunlight.
Shelf life is up to two years under recommended conditions.
