Product Description
HFFR silane grafted compound moisture curable by addition of a catalyst masterbatch (Sioplas method). It consists of a polyolefin base containing a fire retardant system that contributes to give the cable self-extinguish properties without halogenidric acids evolution, toxic and corrosive gases and dark smoke emission. This material complies with RoHS requirements.

Additional Information
coloring
  • EVA based masterbatches added at 1.2-1.5% (approx.) by weight; in order to avoid scotching problems during processing, predrying of colour masterbatch is suggested if moisture absorption occurred during storage (4-6 hours at 60-70°C).

storage
  • The product should be stored under the following conditions:
    • closed and unbroken bags
    • ambient temperature not exceeding 30°C
    • avoid direct exposure to sunlight and weathering

  • Product alterations could occour due to extended period of storage. Its use within six months from the production date is suggested.
  • Solvay Padanaplast S.p.A. accepts no liability of any kind in case the above mentioned conditions are not fulfilled.

packaging
  • 25 kg moisture-resistant bags on 1375 kg pallet.

Extrusion Notes
processing
  • COGEGUM® GFR/360 pregrafted base must be added with Catalyst CT/2-HP masterbatch to promote curing. Catalyst dosage is 5% by weight and blending must be done just before using (2-3 hours max.), preferably in the extruder hopper. Catalyst doesn't need any predrying.
  • The pregrafted base compound is sensible to moisture; open bags must be used within few hours.

extrusion equipment
  • Standard extruders for thermoplastics equipped with low compression screw (1:1.2-1.4 compression ratio and 20-25 L/D ratio are suggested), and an adequate barrel thermoregulation
  • Screw cooling not required.Filter net: none. Compression tools suggested.

curing
  • by immersion in hot water at 60-70°C
  • by exposure to low pressure steam (about 0.15 bar)
  • by exposure in ambient at 10-30°C for some days

  • In all cases curing time depends on insulation thickness; for 0.7-1.2 mm wall thickness 3-6 hours are generally necessary in case of forced curing in hot water and 12-16 hours in case of curing in steam room; in case of self curing, time depends also on the specific ambient conditions.
