Premium double-sided foam tape for medical assembly with acrylic adhesive, 45 mil thickness, immediate handling strength, UL certified, suitable for high and medium surface energy materials.
The 3M™ VHB™ Medical Assembly Tape MA4941P is a premium double-sided foam tape engineered for permanent bonding applications in medical device assembly and industrial manufacturing. This specialized tape features a multi-purpose acrylic adhesive with a conformable foam core backed by densified kraft paper liner, delivering a total thickness of 45 mil (1.1 mm). The tape provides an excellent balance of strength, conformability, and adhesion to both high and medium surface energy materials, making it an ideal alternative to mechanical fasteners such as rivets, welds, and screws.
Designed for fast and easy application, this tape offers immediate handling strength without requiring fixtures or cure time, enabling rapid assembly processes. The closed-cell acrylic chemistry provides exceptional durability and can withstand extreme environments, resisting both high and low temperatures as well as moisture. With a maximum operating temperature of 300°F (149°C) and a 24-month shelf life, this tape maintains consistent performance across diverse applications including transportation, appliances, electronics, construction, signage, and general industrial use.
The MA4941P variant is specifically formulated for medical assembly applications where reliability and performance are critical. It effectively bonds to aluminum, stainless steel, galvanized steel, acrylic, polycarbonate, ABS, and other high and medium surface energy substrates. This versatile tape is UL GREENGUARD™ and UL GREENGUARD™ Gold Certified, helping to contribute to LEED® credits while delivering superior bonding and sealing capabilities for demanding industrial applications.
