At NEDC we are a manufacturer of all types of gaskets. One of the main types of products our gaskets go into is LED lighting fixtures. To be certain, many types of our products go into LED lighting fixtures. Our gaskets, our thermal pads, and our electrical insulators go into them. In this blog, we discuss our gaskets.

The outdoors can be tough and stressful on the sealing of these fixtures. In New England, we see all sorts of weather, snow, rain, sunshine/humidity (mostly in the summer), and some pretty windy days. With the wind-chill during winter, it can turn pretty darn cold. These gaskets are expected to perform day in and day out.

Types of Sealing Challenges for LED Gaskets:

These LED lighting fixtures can include:

-Street Lights

-Internal housing lights

-LED Enclosures

-LED Bezels

Different Types of Sealing Solutions for LED Gaskets:

At NEDC our most common solution for these applications usually involves our trusty friend, in silicone rubber. These silicone rubbers include silicone foam, silicone sponge, and silicone solid solutions. Silicone is incredibly reliable due to its low compression set, its great humidity, and its environmental properties. In addition, silicone is widely known for its temperature resistance. 

Converting Methods:

At NEDC, we have several different types of machines to cut LED Gaskets. We utilize a combination of waterjet cutting and die-cutting to be able to cut gaskets into custom shapes required by our customers. At NEDC, we manufacture gaskets to customer-supplied drawings. The type of material, and the customer-supplied drawing may change the method of cutting used.

Silicone Foam Rubber:

This material has great fire resistance, along with fantastic UV, and other environmental resistant properties.

Silicone Foam Products can include:

NORSEAL F12 & F20 from Saint Gobain Performance Plastics

BISCO HT-800(Medium), HT-820(Firm), HT-840(Extra-Firm), HT-870(Soft), from Rogers Corporation

Closed Cell Silicone Sponge Rubber:

Closed Cell Silicone Sponge is available in a wide range of densities and thicknesses. It typically comes with a fabric finish on both sides of materials.

Closed Cell Silicone Sponge Products can include:

Some popular commercial silicone sponge products are from Saint Gobain Performance Plastics are NORSEAL R10400, R10450, R10460(Medium), R10470(Medium or Firm), R10480(Soft or Medium) 

In addition, specifications such as ASTM/Aerospace/Military Specifications are available with silicone sponge such as ASTM D6576, AMS-3195, AMS-3196, MIL-R-46089, amongst others.

Solid Silicone Rubber:

LED Gaskets are made out of Solid Silicone Rubber. It is available in an incredibly large amount of custom variations, including high-low durometer, high-low tensile strength, stringent specifications, colors and more.

Silicone Solid Rubbers Products can include:

Popular Commercial Silicone Rubber Sheeting from Saint Gobain Performance Plastics are CHR 9030(30A), CHR 9040(40A), CHR 9050(50A), CHR 9060(60A) amongst others.

In addition, solid silicone rubber are available with AMS/Military/ASTM specifications such as ZZR765, A-A-59588, AMS-3301(40A), AMS-3302(50A), AMS-3303(60A), and AMS-3304(70A).


Most times with products that NEDC is supplying, they are available with a tape on the back of the product. Considering that, it is especially important to have adhesive assistance with LED Gaskets. Gasketing materials such as silicone rubber are available with tapes such as acrylic or silicone for adhering to the application. Acrylic tapes such as 9472, 9469PC, or 9485PC from 3M Company may accommodate different applications of LED sealing applications.
