NBR Nitrile Rubber Waterproof Close Cell Foam For Building
Construction
Rubber Foam refers to rubber that has been manufactured with a
foaming agent to create an air-filled matrix structure.
The main physical properties of foam rubber are generalized as
being Lightweight, buoyant, cushioning performance, thermal and
acoustic insulation, impact damping, and cost reduction
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.
Nitrile Foam Tape:
As Vinyl Nitrile foam has so many good physical properties, they
are quite suitable to be manufactured as foam tape with or without
adhesive backing. By utilizing our high efficient automated
slitter, we have the capability to process PVC/ Nitrile foam tape
in various custom sizes.
