Product Information
Beneficios
- Based on an organic metal phosphinate
- Not hygroscopic, insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene
- Good hydrolysis resistance
- Halogen-free flame retardant with a high phosphorus content which is suitable for use in both thermoplastic and thermoset applications to meet the most stringent fire retardancy standards
- Particularly suitable for very thin adhesive applications like flexible printed circuit boards due to its specifically designed particle size distribution; can be readily dispersed in epoxy resin systems when a high shear mixer is used
- Low smoke toxicity
- Non-halogenated flame retardant with favorable environmental and health profile

Exolit OP 945 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.
Due to its specifically designed particle size distribution, Exolit OP 945 is particularly suitable for very thin adhesive applications like flexible printed circuits. It can be readily dispersed in epoxy resin systems when a high shear mixer is used.
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 modified resins
or other flame retardants like ATH
