High temperature polyamide with halogen-free flame retardant for LED packages

January 30, 2013 // By Julien Happich
DSM Engineering Plastics has introduced Stanyl ForTii LED LX, a LED-specific grade of Stanyl ForTii high temperature polyamide with halogen-free flame retardant, aimed at LED packages.

High-flow Stanyl ForTii LED LX is a mineral-filled grade, and its excellent UV resistance sets a new standard for LED packages, says the manufacturer. The material delivers a reliable performance over time and, more specifically, high initial reflectivity, as well as excellent mechanical strength. Its high flow properties make it suitable for use in high cavity tools. This enhanced reflectivity of Stanyl ForTii has an immediate effect on the LED package light output and enables LED suppliers to improve their key specifications. The new material is said to outperform competitive PPAs thanks to its specific polymer structure.

High reliability and LED lifetime are further enhanced through the material's excellent adhesion to silicones and epoxy encapsulates, as well as to metallic lead frames, avoiding chip degradation due to moisture or air diffusion through interfacial delamination phenomena. With Stanyl TC, designers can reduce weight of lamps, while increasing electrical safety and productivity in manufacturing. Total system costs can be reduced by up to 30-40% compared with cast aluminium.
