Vinyl/Nitrile (PVN) Closed Cell Foam

Fostek Corporation manufactures high quality plastic and rubber blended, closed and semi-closed cell foams in our continuous roll process as well as in custom profile shapes.  Fostek has developed and produces our family of Vinyl/Nitrile (PVN) & Neoprene closed cell foams in our IATF 16949:2018 certified production facility in Bedford, Virginia.

What is Fostek’s “point of difference?”

Fostek Corporation defines our Vinyl/Nitrile (PVN) & Neoprene closed cell foam family as foams, when tested to ASTM D1056 @ 25% compression deflection, results in a range of 13.8 kPa up to 89.6 kPa max. The corresponding psi (pounds per square inch) products are in the 2-5 psi; 5-9 psi; and 9-13 psi ranges.

Fostek’s point of difference encompasses choices of compression deflections to target specific applications and needs for our customers.  Fostek can “tune in” its foams for new engineering and design challenges to deliver the desired performance.

What is Vinyl/Nitrile Closed Cell Foam used for?

Fostek’s vinyl/nitrile (PVN) & Neoprene closed cell foams are utilized in many of the same applications as our semi-closed foams. Fostek’s closed cell vinyl/nitrile (PVN) foam delivers excellent performance and durability for a variety of applications. Our proprietary “family” of vinyl/nitrile (PVN)  & Neoprene foam products are used in the automotive industry as well as in appliance, weather stripping, and general industrial uses for a variety of applications and can be either die cut or in custom profile form, often with PSA.

• NVH (noise, vibration, & harshness) seals, gaskets, pads, closure strips, pillar stuffers, cushioning in or around windshields, door panels, instrument panels, headliners, etc.
   
• Acoustic / sound control in or around windshields, door panels, instrument panels, headliners, etc. These may be used alone or in composite to achieve STL (sound transmission loss) targets in a vehicle component “system” (i.e. a door “system” that includes the metal door, the glass, and the inner cabin door trim panel).

NOTE: In some systems where oil resistance is important, Fostek’s Vinyl/Nitrile (PVN) foam with skin 2 sides might be used at 5mm (+/-) as a functional acoustic/moisture control material.

• HVAC seals and gaskets providing air and water sealing
   
• APPLIANCES utilize these foams for the same performance reasons as listed above
   
• Other typical applications for our Vinyl/Nitrile (PVN) & Neoprene foams include weather stripping, construction seals, window glazing seals, etc. These are used in custom profile form as well as die cut and stripping.

More information about Fostek Vinyl/Nitrile (PVN) & Neoprene Closed Cell Foam

Fostek’s continuous roll technology produces Vinyl/Nitrile (PVN) & Neoprene closed cell foam rolls that range in gauge from 3mm thick to 38+ mm thick. Fostek’s closed cell technology produces a cell structure consistent with similar products offered in the market. Rolls are available in a variety of widths and lengths. The most common widths are a roll of a minimum width of 54 inches and a roll with a minimum width of 27 inches. Black is the most common color. Depending on certain parameters, closed cell foams are available with skin-two-sides, skin-one-side, and no skin. The most common packaging for these products to adequately protect them during shipping and handling is to place them in boxes on skids.
