    The PRIMO® XT N381 matte/satin 2mm is a diffuser with a one-sided matte and a one-sided satinated surface. Both surfaces can be used, which gives this diffuser a high amount of flexibility.

    The PRIMO® XT N381 matte/satin has a one-sided matte surface and a one-sided satin surface. The diffuser is 2mm thick and has a light transmission of 71%. Light transmission refers to the amount of light that comes through the diffuser. It is measured on the other side of the light diffuser than where the light source is positioned. The diffusivity, a score that refers to how well the light is scattered, is 0.56. That gives the PRIMO® XT N381 2mm a distance factor of 1.8. This means that the distance between the diffuser and the leds needs to be 1.8 times larger than the distance between the led strips or led button cells themselves to get a nice and diffuse light result.

    Professional diffuser

    The PRIMO® XT N381 diffuser is part of our collection with professional diffusers. With the help of extremely precise process control and the use of nano additives, the professional diffusers are more efficient than standard diffusers. They offer a higher light transmission with the same diffusivity or a higher level of diffusivity with the same light transmission. The light transmission is a measurement of the amount of light transmitted. The diffusivity refers to to how well a diffuser scatters the light.  A diffuser that has a higher score on the variable ‘efficiency’ performs better. An efficient diffuser is more expensive to purchase, but earns itself back by saving energy of increasing the light output.

    Material characteristics

    The PRIMO® XT N381 is made from extruded acrylic. Light diffusers from extruded acrylic have good to excellent light technical properties and can be fabricated easily. The material is quite vandal proof, UV-stable and colourfast. It can be safely used outside, the colour doesn’t change when exposed to the sun. The fire classification of cast acrylic is E according to fire norm EN 13501. This is the European (EU) classification.

    Extrusion is a continuous process, creating large batches per production run. This makes the material cheaper than cast acrylic, but it is also less flexible. Our assortment is less broad, because the minimum batch per production run is large. An additional benefit of this production method is the minimum thickness tolerance, compared to cast acrylic.

    Stock of the PRIMO® XT N381 matte/satin 2mm

    The PRIMO® XT N381 with a one-sided matte surface and a one-sided satin surface in 2mm thickness is in stock in sheet size 3050mm x 2050mm. If you need a smaller size for your application, we gladly offer material cut to size.

    Applications for the PRIMO® XT N381 matte/satin 2mm

    If you are looking for a diffuser that combines good diffusivity with a high level of light transmission, the PRIMO® XT N381 matte/satin 2mm is a great choice. With the minimum amount of thickness tolerance and excellent light technical properties of extruded acrylic,  this diffuser can be applied in many circumstances. The PRIMO® XT N381 can be used for light fixtures, displays, signing, profiles and window frames. Barfronts, signing and other esthetic applications are also possible. Because the material is UV stable and the colour is not influenced by the sun, you can safely use the sheet inside and outside.

    Do you want to place the diffuser close to the light source? Then the PRIMO® N385 in 3mm or the PyraLed® YT275 in 1.8mm are better options. These diffusers offer a high level of diffusivity. This allows you to place the diffuser close to the light source while still having a diffuse and even light result.

    For constructive applications like floors, walls and full bars and desks, we recommend a thicker diffuser, like our PyraLed®3 10mm or the PyraLed® OPY3 satin/satin 10mm. These diffusers are made from cast acrylic.

    Looking for inspiration? Please check our Acrylic community. You can find many applications with light diffusers. There are also many other applications with acrylic on the platform.

    Fabricating the PRIMO® XT N381 matte/satin 2mm

    Mandatory VAT-number

    Dear customer,

    From 1 July 2021, new VAT rules will apply to Dutch businesses. Due to this new legislation, we have decided to only deliver to foreign customers with a VAT number. It is therefore not possible as a private customer to order in our webshop without a VAT number. We will of course be happy to refer you to a reseller.
