- Product Applications
- Exolit OP 950 is a flame retardant for thermoplastics and synthetic fibers, distinguished by high efficiency due to its high phosphorus content.
- Developed specifically for use in polyesters, suitable for injection moulding and fiber applications, providing excellent physical and electrical properties.
- The recommended dosage for PET fibers is 5-10%, with 5% achieving a limit oxygen index (LOI) of 33%. Exolit OP 950 must be incorporated before the spinning process.
- In PBT, a dosage of 10-15% Exolit OP 950 with 10-15% nitrogen synergists like melamine polyphosphate or melamine cyanurate typically ensures the UL 94 V-0 classification for electrical components (1.6 and 0.8 mm thicknesses).
- In PET, less flame retardant is required to pass UL 94 V-0.
- The dosage varies based on the polymer grade, processing conditions, and glass fiber reinforcement.
- Exolit OP 950 melts under processing temperatures above 200 °C and is miscible with molten polyesters.
- Predrying the polyester is crucial, aiming for moisture content below 0.05% (by wt.) for PBT and 0.005% for PET. Predrying of Exolit OP 950 is not necessary but recommended (e.g., 4 h at 120 °C) if low moisture content is required.
- Customary powder processing methods for polymers can be used with Exolit OP 950.
- Adhere to the VDI Guideline 2263 on dust fires and explosions, or the relevant national regulations.
- Ensure homogeneous dispersion of all components and ensure that the polymer melt temperature does not exceed 300 °C.
