Thermal Insulation NBR Rubber And Plastic Foam For Central AC
Ducting
NBR foam sheet material, also called Vinyl Nitrile foam or PVC NBR
foam, is one of most useful and excellent foam materials. They can
be fabricated to be Nitrile foam tapes, strips, gaskets, pads,
sheets and so on. NBR foam are mostly used for seals, gaskets, heat
insulation, soundproof and vibration dampening applications. They
are foamed polymer blend of PVC and Nitrile rubber materials. It is
foamed Nitrile foam not like the solid and rigid Nitrile rubber.
Egg Crate Convoluted Nitrile Foam Sheet:
NBR foam sheet can also be convoluted into egg crate convoluted
Nitrile foam just like polyurethane foam. The convoluted Nitrile
foam can be powerful sound barriers and present superior acoustic
insulation and fire retardance performance for lots of application
including acoustic conference rooms, theaters and required testing
rooms etc.
NBR Foam Gaskets, Seals and Strips:
PVC NBR foam sheet has outstanding sealing and insulation
abilities. They can also easily be fabricated to NBR foam gaskets,
foam seals and foam weathering strips which widely used for
construction and building, automotive and other industrial
applications.
