3M™ VHB™ Tapes
3M™ VHB™ Tapes have proven over time to be high strength, durable bonding
materials. The long-term aging resistance lies in the polymer comprising
these tapes. The chemical bonds that make up the polymer chains consist of
carbon-carbon single bonds that are highly resistant to energy in the form of
heat or ultraviolet light, as well as chemical attack. In less durable foams or
adhesives, such conditions could lead to cleaving of the polymer backbone
and thus a weakening of mechanical properties. In the case of acrylic adhesives
and foams, however, additional crosslinking is chemically favored over chain
scission (cleavage). This means that, rather than undergoing a process of
decomposition, the acrylate materials will tend to build modulus very slightly
over extended exposures. This translates to a stronger, long lasting bond.
