Polyurethane-, epoxy- and silicone-based reactive resins are used for a variety of products in the lighting industry. The applications range from the casting of sensors or ballasts and the sealing of the luminaire to the bonding of LED modules into a tube. The characteristics of the products for the respective application vary, depending both on the technology of the lamp (e.g., fluorescent or LED) and on its specific use.
Flame-retardant, UL-listed foam gaskets for the lighting industry play a significant role in preventing or delaying the spread of fire. At the same time, the sealing systems must meet the highest chemical and mechanical requirements, as well as environmental standards. This provides the developers of resins with major challenges, because the use of fire retardants can affect the performance of the sealing systems.
