V0 Transparent PC Sheet Flame Retardant FR2025 PC Flame Retardant Additive Ultra-thin Ultra-transparent

PC Flame Retardant Additive PPFBS 

(QB- FR 2025)

Product Name: UL94 V-0 Transparent PC Sheet Flame Retardant FR-2025

Application: PC ultra-thin and transparent Sheet

Product Description

1. Perfluorobutanesulfonic acid potassium (PPFBS) FR-2025 is a high-temperature resistant additive for transparent polycarbonate (PC). It does not contain bromine or chlorine compounds, has high solubility in polycarbonate, and requires minimal usage. It is used to produce fully transparent grades of polycarbonate resin without significantly affecting the resin's physical properties.
2. Its chemical and thermal stability allows it to withstand temperatures exceeding 450°C, making it suitable for engineering plastics requiring high-temperature processing.
3. Its effective addition level is very low, ranging from 0.06% to 0.08% by weight, at which PC resin remains fully transparent and passes the UL-94 V0 vertical burning test.

Physical Properties:

Appearance: White solid powder

Melting Point: 273°C

Density: 899-945 kg/cm³

Thermal Decomposition Temperature: 499°C

Usage and Dosage:

When manufacturing flame-retardant PC, FR-2025 can be directly added to the mixing kettle at 0.06%-0.08%, or it can be made into masterbatches at 1-3% and then added to the mixing kettle according to the ratio.

After thorough mixing, the temperature of the PC should be maintained above 280°C, at which point the FR-2025 crystals undergo phase transformation and crosslink with the PC, resulting in flame retardancy. Subsequent extrusion yields fully transparent polycarbonate. Twin-screw extrusion typically yields better results.

Advantages of 3M flame retardant FR-2025:

1. Excellent chemical and thermal stability, withstands temperatures up to 450°C; suitable for high-temperature resistant PC engineering plastics.
2. FR-2025 is a perfluorinated potassium salt, free from bromine and chlorine compounds; environmentally friendly.
3. High solubility in polycarbonate allows for the production of fully transparent PC resin (VTM-0 for films and sheets).
4. Highly efficient and requires minimal usage; achieves UL94 V-0 flame retardant rating at only 0.06-0.08% addition level.
5. Minimal impact on the physical and mechanical properties of the resin itself.
