Additional Information	Nominal Value	Unit	Test Method
Tests reported are performed on pressed or extruded specimens, added with 5% of Catalyst CT/5 UV and crosslinked in hot water at 95°C for 6 hoursColoring 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 instructions
Processing Cogegum® GFR/320 pregrafted base must be added with Catalyst CT/5 UV 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 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.
