Product Information
Benefits
- White powder, not hygroscopic, insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene
- Can easily be dispersed in solvents like acetone or MEK
- Halogen-free flame retardant with a high phosphorus content, suitable for use in both thermoplastic and thermoset applications where the most stringent fire retardancy standards must be met
- for epoxy based laminates for printed circuit boards like halogen-free FR-4 and CEM-3 laminates; can be readily dispersed in epoxy resin systems when a high shear mixer is used
- Does not increase water pick-up after Pressure Cooker test
- Low smoke toxicity
- Non-halogenated flame retardant with favorable environmental and health profile

Applications
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.
Classification: UL 94: class V-1, 1.6 mm
concentration: approx. 10 parts Exolit / 100 parts resin
Classification: UL 94: class V-0, 1.6 mm
concentration: approx. 30 parts Exolit / 100 parts resin
or in combination with other flame retardants like ATH
Note: There are various third party patent rights relating to the use of Exolit OP 930 in polyester based flame retardant applications. Further details can be obtained from Marketing Specialties Business, BS Flame Retardants +49-6196-757-8109.
