Foam tapes are available in two general types; double side coated or single side coated.  If used as a mounting tape, then the double coated version with pressure sensitive adhesives on two sides of the foam carrier is supplied.  The foam carrier is beneficial because it fills gaps and accommodates variation between the mounting surfaces.  Also on a microscopic level, a foam carrier will help the adhesive wet out and fill the microscopic peaks and valleys of the mounting surface better than a stiffer double coated film tape.  There are many varieties of foam carriers for making tapes.  The characteristics of the foam, coupled with the characteristics of the adhesive will determine which foam tape is best for the application. 

 

 

A few of the more common types of foam tapes are notes below.

Foam Type Typical Density PCF* Typical Adhesive Max Operating Temp** Acrylic 37 - 60 Acrylic 230ºF (110ºC) PVC 4 - 14 Acrylic 200ºF (93ºC) Neoprene/EPDM/SBR  5 -1 3 Rubber or Acrylic 158ºF (70ºC) Polyethylene 2-6 Rubber 120ºF (39ºC) Polyethylene 2-6 Acrylic 180ºF (82ºC) Polyurethane 1.3 - 2 Rubber or Acrylic Varies PVC 5 - 17 Acrylic Varies Silicone 12 - 43 Acrylic 300ºF (149ºC) Silicone 12 - 43 Silicone 500ºF (260ºC) Sponge Rubber 26 Acrylic 200ºF (93ºC) Urethane 25 - 30 Acrylic 200ºF (93ºC) Vinyl Nitrile 4 - 6 Acrylic 158ºF (70ºC)

 

* PCF = Pounds per cubic foot

** check product data sheets because the surface the tape is applied to may have a limiting use temp less than that of the tape.
