Closed cells Foam Strips, BM series
The foam ring is designed for gripping products with an uneven or ridged surface, e.g.:
• Sawn wood, sheet metal, flat surfaces with bumps or hollows.
• All granular surfaces to which suction pads cannot adhere correctly and are therefore not airtight.
COVAL offers two types of foam strips: the BM series rolls and the VSBM series ring version.

BM-SPTR version: Nitrile beveled foam strip
• Nitrile (NBR - Black): Good resistance to oil. The nitrile foam strip can only be glued to nitrile suction cups. Closed cells.

• Silicone (SI - White): Heat-resistant up to 160°C (320°F), does not leave marks on products handled. Do not use the silicone foam strip for gripping products before painting or lacquering.
Closed cells.

• Natural rubber (NR) : Abrasion resistance. Open cells. Use with turbine (strong suction) for gripping products with very uneven surfaces, such as slabs of washed gravel.
