Exolit OP 930 is a halogen-free flame retardant with a high phosphorus content which is suitable for use in both thermoplastic and thermoset applications where the most stringent fire retardancy standards must be met.
One application is epoxy based laminates for printed circuit boards. Halogen-free FR-4 and CEM-3 laminates can be produced by using Exolit OP 930. It can be readily dispersed in epoxy resin systems when a high shear mixer is used. Exolit OP 930 does not increase the water pick-up after Pressure Cooker test.
