3M™ VHB™ Tape 5981-040 is a premium ultra thin double sided acrylic foam bonding tape specifically developed for electronic device manufacturing. Unlike conventional foam tapes or liquid adhesives, it features a unique multilayer construction consisting of a thin carrier film coated with high performance modified acrylic foam adhesive on both sides. This advanced design delivers excellent bonding, waterproof sealing and exceptional bonding strength, even with narrow bond lines. Its Polyester (PET) carrier enables precise die cutting and clean removability for rework and allowing conversion into ultra narrow bond lines as small as 0.5 mm.
Designed for today’s compact electronic assemblies, 3M™ VHB™ Tape 5981-040 provides reliable long-term performance while simplifying manufacturing processes and improving production efficiency.
- Ultra-Thin 0.40 mm Construction:- Engineered with a total thickness of just 0.40 mm (16 mil), making it ideal for compact electronic devices requiring minimal bond-line thickness.
- Narrow Bond Line Capability:- Can be precisely converted into bond lines as narrow as 0.5 mm, making it suitable for miniature electronic components and precision assemblies.
- High Bond Strength:- Provides exceptional adhesion to plastics, metals, and glass, ensuring durable structural bonding even in demanding applications.
- Excellent Impact Resistance:- Its modified acrylic foam construction effectively absorbs shock and vibration, protecting delicate electronic assemblies from impact damage.
- Outstanding Anti-Lifting Performance:- Designed to resist edge lifting and maintain reliable adhesion even after prolonged exposure to heat and mechanical stress.
- Waterproof Sealing:- Offers excellent waterproof performance, including IPX8-level water resistance, helping protect sensitive electronic components from moisture ingress.
- Improved Reworkability:- Unlike many permanent bonding tapes, it offers better removal characteristics, making component replacement and repair easier during manufacturing or servicing.
- Pressure Sensitive Adhesive:- Provides immediate handling strength without requiring curing, reducing production time and increasing assembly efficiency.
- Excellent Conformability:- The flexible acrylic foam easily adapts to uneven surfaces while maintaining consistent bond strength across the entire bonding area.
- Long-Term Durability:- Highly resistant to environmental aging, temperature variations, moisture, and vibration for dependable long-term performance.
