Compounding system

Overview
HFFR compound production covers the processes and equipment required to formulate PVC-based cable compounds containing Halofluoroalkane flame retardant additives. The production chain includes raw material storage, controlled pneumatic transfer, high-precision dosing and integrated automation to ensure reproducible compound quality suitable for fire-resistant cable manufacturing.

The Importance of HFFR Compound Production

• Fire Resistance: HFFR formulations improve the flame-retardant performance of PVC cable jacketing and insulation.
• Environmental Compliance: Use of HFFR additives enables formulations that meet applicable environmental and safety regulations.
• Product Quality: Consistent mixing and accurate dosing produce homogeneous compounds with predictable properties.
• Efficiency and Cost Control: Automated handling and dosing reduce material losses and operational costs.
