- Tabbing tape for polyethylene film liners
3M™ Acrylic Foam Tapes, often used in conjunction with 3M™ Splicing Tape 4240, are proven high-performance attachment systems for bonding automotive accessory and trim parts. These double-coated tapes combine acrylic adhesives with viscoelastic foam cores. Typical applications for 3M Acrylic Foam Tapes include attaching trim parts and bonding seals throughout the car body. Utilizing advanced technology, 3M™ Acrylic Foam and Acrylic Plus Tapes are designed to adhere to a wide variety of paint systems, including low surface energy and improved scratch- and mar-resistant paints. They exhibit unique core properties that allow for stress relaxation and exhibit high adhesion values to automotive paint systems.
Thin, High Temp Performance
Tapes with polyester backing like this one withstand heat during high-temperature masking operations. An exceptionally thin backing that resists tears, abrasion, and the effects of aging. Polyester backed tape allows you to splice, insulate, reinforce, protect and seal.
Benefits of Polyethylene Film
Low tensile strength and high tear resistance are two of the major benefits of polyethylene film. For applications where film elongation is a factor, polyethylene is a popular choice. Polyethylene film has good moisture resistance and durability. It is commonly available in colors of white, clear and translucent.
Better Science for Better Adhesion from 3M
Since 1925 when a 3M lab assistant invented masking tape, 3M has been applying science to life — developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations - and all of it goes into each 3M product developed for automotive OEM, like 3M™ Splicing Tape 4240.
