New England Die Cutting(NEDC) manufactures gaskets of all sorts, sizes, colors, and materials. Gaskets is a generic term for something that seals out medias such as fluids, gases, dust, and other things that may be harmful to the inside of an application. With that said, there are many different types of gaskets that are held under that umbrella. When NEDC got started in 1982, gaskets were its first product line. For that reason, NEDC is very experienced in the gasket business, equipping itself with countless machines that cut materials into unique custom shapes.

Solid Rubber Gaskets

Solid Rubber Gaskets are generally referring to rubber gaskets made out of the common elastomers such as silicone, fluorosilicone, neoprene, EPDM, nitrile, fluoroelastomer, and others. They can often be offered with a fiberglass insert for pressurized applications. In addition, electrically conductive gasket options can be provided.

These gaskets are die-cut, waterjet-cut, and laser-cut. These gaskets are available in sizes ranging from .050’’ to 14 feet in length.  Commonly known solid rubber products include materials from OEMs such as 3M, Rogers, and Saint Gobain.

VHB Gaskets

VHB Gaskets refer to VHB Tape materials provided by 3M cut into shapes that offer gasketing solutions. The reason these acrylic foam tapes are used is because they offer great bonding strength that can seal out many mediums if properly applied. These tapes are commonly used on computer like tablets. These acrylic foam tapes include ultra thin and thick options to accommodate different applications. These tapes oftentimes are used in applications that require permanent bonds. The three VHB tape families include 5952, 4941, and RP tapes.

Sponge/Foam Gaskets

Sponge/foam gaskets include cellular products that allow for less compression force than is normally required to seal out different medias. These materials have been chemically or otherwise expanded but are often made out of similar base materials that solid rubber gaskets are made out of.  Some examples of foam/sponge gaskets include silicone sponge, fluorosilicone sponge, neoprene sponge, PORON(urethane foam), sponge blends, and other cellular selections. Sponge and foam gaskets are highly customizable. Some examples of that include thermally conductive options, electrically conductive options, and ultra-soft or firm options.

Commonly known cellular foam/sponge products include:

-Norseal R10450, R10460, R10470, R10480, and R10490 by Saint Gobain

-PORON Urethane Foams by Rogers Corporation

-BISCO HT-800, HT-820, HT-840, and HT-870 by Rogers Corporation

Plastic Gaskets

Oftentimes people use materials that are plastic for gaskets. Some materials used include PTFE(Teflon), Nylon, UHMW and more. These materials are cut out of flat sheet materials by NEDC.

NEDC is a supplier of gaskets to a wide variety of customers. NEDC does this through die-cutting, waterjet cutting, laser cutting or otherwise converting materials into custom shapes usually from a DXF or other electronic file. Many times these gaskets can be provided with adhesive backing for ease in assembly. Most of these gaskets are flat in nature.
