Foam Sales NBR (Nitrile Rubber) sheeting is a flexible, synthetic rubber copolymer. NBR sheet is a pliable, resilient closed cell material used for both thermal and sound insulation. The sheet is black in colour with smooth skin on both sides that forms the outer exposed insulation surface.
The expanded closed-cell structure of Foam Sales NBR makes it an efficient thermal insulation material, ideal for cabinets, larger pipes, fittings, duct-work, vessels and curved/irregular surfaces. NBR is effective as thermal insulation for temperatures ranging from -40 to +100C. In case of fire the product is self-extinguishing when removed from the flame source.
NBR sheet is also used for sound insulation to line engine boxes and bays, including marine applications where buoyant closed cell foams are required.
Foam Sales' NBR is resistant to grease, mineral and vegetable oils, petrol and diesel fuel, to alcohol, and to weak acids; more-so than natural rubbers. It is attacked by ozones, ketones, esters and aldehydes.
These NBR variants are sold off the roll by the linear metre, or in full rolls at 20% discount.
