How Good Is The Flame Retardancy?

The major characteristic of SunForce BE – the first-of-its-kind material certified with UL94 V-0 – is its flame retardancy.

SunForce™- The First-Of-Its-Kind Certified With UL94 V-0

SunForce compared to general plastics

The major characteristic of SunForce™ BE is its flame retardancy. Flame retardancy literally means that the material cannot burn. Plastics generally burn when in contact with fire. Furthermore, since they are comprised of bubbles of air and readily combustible hydrocarbons, foamed plastics are more combustible than other types of plastics.

SunForce – A flame-retardant foam material

To ensure that the foam material can be used with confidence as a flame-retardant material, we have developed a plastic composition for SunForce based on a highly flame-retardant PPE plastic as the primary component. Used in combination with a unique microfoaming technology, it provides high flame retardancy despite its properties as a foam.

For example, there is often the danger of short circuits and ignition in electronic equipment and components operating at high temperatures, and materials with a product rating of “flame retardance,” or better are required.

While there are a number of indices for flame retardancy, the UL standard is generally used as the point of reference. This UL standard is a set of optional standards from the UL LLC, private third-party safety science organization in the US, and is also registered in many ANSI standards. It has become the de facto safety standard for electrical equipment etc. In the US, electric products without UL certification are not covered by public liability insurance, and as a result, UL certification has become an internationally recognized representative safety standard.

The UL-94 flame retardancy standard also
provides for a range of tests and standards.

SunForce is registered in the Vertical combustion test standard. A flame retardancy level of V-0 or V-1 under the vertical combustion test is required for internal components of electronic equipment, office automation equipment, battery components, and medical equipment etc. SunForce is usable in such applications.

Furthermore, the (4) Foamed material combustion test standard has been available for some time. Testing conditions are easier than for (1) Vertical combustion test, and when testing HF-1 or HF-2 foamed materials using (1), the material is able to burn completely without self-extinguishing.
