| Cogegum® HFFR -Halogen Free Fire Retardant compound Polyolefin based thermoplastic compound containing a fire retardant system that contributes to give the cable self-extinguish properties without halogenidric acids evolution; furthermore, toxic and corrosive gases emission and smoke generation are particularly reduced. These characteristics make this compound suitable in all applications where the fire behavior of cable materials is one of the main concerns to be considered in establishing a high safety level in public places. This material complies with RoHS requirements. standard complying - EN 50363-0 M1, M9; EN 50363-7 TI6, TI7; IEC 60502-1 ST8; Cenelec HD 624.7 S1; Cenelec HD 624.6 S1; VDE 0207 HM2, HM5, HJ2; IEC 60092 SHF1; UNE 211002 TIZ1; UNE 21123-4 Additional Information: Tests reported are performed on pressed or extruded specimens 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 undamaged 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: 12 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 box Extrusion Notes: 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 - don't use screw thermoregulation - filter net: not necessary; in case, use 40-80 mesh/cm² max. Anyway the use of the breaker plate is advisable, in particular using low compression screws Information provided by Solvay Specialty Polymers. |
