Plastazote®, sometimes called LED foam, is a semi-transparent foam used to diffuse LED light. The sheets are as flexible and durable as EVA Foam and can be cut, shaped with heat, and glued with contact adhesive in the same way.

The diffusing properties of Plastazote® help to diffuse light and to create a soft uniform illumination when used in lighting installations and with LED strips

Plastazote® reduces and blends the dots of Neopixels/LED strips. The thickness of the foam and the distance from the LED's will effect the amount of diffusion achieved. The thicker the foam the more diffused the lights will be.

Since Coscom Cosplay Supplies has made this material available to our cosplay and other industry customers, Plastazote-LD45@ has become an absolute favorite with the community. 

Painting instructions:

Plastazote® is an open cell foam. When painting, we recommend first heating the surface of the foam to collapse the cells and make the surface smooth.

Prime the surface with a clear flexible primer such as Flexbond® or Cosflex®

For best results we recommend using a transparent paint to allow the light to pass through, or use a thinned acrylic paint lightly applied with an airbrush.

Sheets are available in 4mm 6mm and 8mm.
