Product Description
Cogegum® XLPO-HFFR - Crosslinkable Halogen Free Fire Retardant compound

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
Tests reported are performed on pressed or extruded specimens, added with 3% of Catalyst CT/2 and crosslinked in hot water at 95°C for 6 hours

Coloring
  • EVA or PE based color masterbatches added at 1.2-1.5% by weight; in order to prevent precrosslinking during processing, predrying of colour masterbatch is suggested (4-6 hours at 50-60°C)

Storage
  • The product must be stored under the following conditions:
    • closed and undamaged bags
    • ambient temperature not exceeding 30°C
    • avoid direct exposure to sunlight and weathering
  • Product alterations could occur due to extended period of storage
  • Shelf life: 9 months
  • Solvay Specialty Polymers 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
  • 750 kg carton box

Extrusion Notes
Processing
  • Cogegum® GFR/340 pregrafted base must be added with Catalyst CT/2 masterbatch to promote curing. Catalyst dosage is 3% 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 if stored in dry conditions in the original closed bags; in case, predrying can be made at 50-60°C for 4-8 hours
  • The pregrafted base compound is sensible to moisture; open bags must be used within 4 hours. Pregrafted base cannot be predried

Extrusion equipment
  • standard extruders for thermoplastics equipped with low compression screw (1:1.2-1.4 compression ratio and 25 L/D ratio are suggested), and an adequate barrel thermoregulation
  • don't use screw thermoregulation
  • filter net: none
  • compression tools suggested

Curing
  • by immersion in hot water at 60-70°C
  • by exposure in ambient, crosslinking time depends on ambient temperature and relative humidity
  • 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.
