3M 4930 VHB Tape White 25 mil 6" x 5yd

3M 4930 VHB Tape — 6 in × 5 yd

This white acrylic foam tape uses the 4930 series to create permanent structural bonds. It replaces mechanical fasteners in assembly, manufacturing, automotive, aviation, construction, electronics, metalworking and general maintenance tasks. The firm foam core distributes stress across the joint while sealing against moisture and vibration. Supplied as a continuous roll with liner included.

Indoor and outdoor structural bonding

Suited for engineers and technicians joining ABS, acrylic, glass, metal, nylon or polycarbonate where rivets, screws or welds are impractical. The tape performs continuously from -31 °F to 230 °F, covering most industrial environments. Not intended for low-surface-energy plastics such as polyethylene or polypropylene without additional surface preparation. Buyers needing a thinner bond line or a different adhesive chemistry should evaluate alternative products.

25 mil nominal thickness

The 25 mil foam thickness determines gap-filling ability and stress relaxation in the joint. It sets the minimum bond-line dimension and influences peel and shear performance on the listed substrates. Verify that this thickness matches the design allowance before specifying the tape.
