HFFR Cable Compounds
HFFR cable is the short form of Halogen Free Flame Retardant cable. Unlike the PVC cable, the materials used in HFFR cable insulation and sheath have been produced as a material that does not conduct flame and poison for a certain time during fire incidents, thus people trapped in fire can have better chances for their rescue. HFFR materials are produced by compounding EVA, PP and PE polymers with ATH (aluminum trihydroxide) or MDH (magnesium hydroxide) in a proportional ratio. HFFR cables are now widely used in indoor buildings, such as airport, subway, hospital, school, shopping mall, office building, and etc.

Delivery_HFFR cable compounds
Many famous cable companies adopts Xinda Co-Kneader to make the HFFR compounds for unique working features.
ATH and MDH fillers are sensitive to the temperature rise, while Co-Kneader has excellent temperature control ability owing to the mild shear features.
Co-Kneader is good at the high filling formulation and HFFR filler usually reaches over 60% of the total materials since excellent distribution & dispersion of Xinda Co-Kneader ensure good quality of final result of HFFR compounds.
Xinda Co-Kneader compounding line is good at producing the following Halogen Free Flame Retardant cable compounds:
- HFFR Cable: Sheath of power cable, control cable, marine cable, etc. with high requirement on halogen free flame retardant property.
- HFFR Cable: Insulation of BV wire, power cord, et with high requirement on halogen free flame retardant property.
- HFFR Cable: Oxygen barrier materials for power cable and control cable with halogen free flame retardant property.
- HFFR Cable: Sheath of B1 power cable and control cable with halogen free flame retardant property.
- HFFR Cable: Insulation and sheath of motor wire, equipment power cord and lan line.
- HFFR Cable: Insulation and sheath for building wire and power cable.
- HFFR Cable: Lan cable, coaxial cable, indoor optical cable and outdoor optical fiber cable.
Why XINDA Co-Kneader is suitable for HFFR compounds
The processing temperature range for ATH and MDH filling materials are relatively narrow. which increases the difficulty to process the HFFR cable compounds. The unique working principle of the Xinda Co-Kneader makes it an ideal equipment in HFFR cable compounds application.
- The L/D is short, and the axial and radial mixing are carried out simultaneously to ensure the best dispersion and distribu- tion mixing effect. Its homogenization time is short, minimizing the residence time of the material in the barrel
- The real melt temperature is measured by the thermocouples inserted into the pins, the temperature curve is uniform, and the process parameters are stable and reliable. the tempera- ture control accuracy can reach ±1℃
- The unique screw design can meet the high filling requirement of inorganic flame retardant fillers
- It can be matched with upstream and downstream equipment, such as feeding system, melt pump, pelletizing system, etc. according to different process requirements
