Material Notes:
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. Standard complying - EN 50363-6 EM8, EM10; EN 50264 EM101..104; IEC 60092 SHF2; VDE 0207 HM3Additional Information: Tests reported are performed on pressed or extruded specimens, added with 3% of Catalyst CT/2-MD UV and crosslinked in hot water at 95°C for 6 hours Coloring - EVA or PE based masterbatches added at 1.2-1.5% 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 50-60°C). Storage - The product must be stored under the following conditions: -- closed and unteared bags -- ambient temperature not exceeding 35°C -- avoid direct exposure to sunlight and weathering - Product alterations could occur due to extended period of storage - Shelf life: 6 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 - 1000 kg carton boxExtrusion Notes: Processing - COGEGUM® GFR/370 pregrafted base must be added with Catalyst CT/2-MD UV 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 waterInformation provided by Solvay Specialty Polymers.
