COHRlastic® F-12 modified cell silicone foam rubber provides excellent flame retardancy (UL 94 V-0) with low toxicity and smoke generation in a conformable expanded cellular material. COHRlastic F-12 is produced in a low 12 lb/ft3 density for light gasketing and insulation applications.

F-12 ranges in thickness from 1/16” (1.59mm) to 1” (25.4mm). The standard color is gray, but it is also available in white and black, with minimum quantity requirements.

F-12 also comes in pressure-sensitive adhesive tape form as Strip-N-Stick® 512AF, with a film-supported acrylic pressure-sensitive adhesive on one side. COHRlastic F-12 offers excellent compression set resistance and resistance to the environment.
