XLPE Compounds - BLS XL 101/102 AND 201/202
The SILANE CROSSLINKED Moisture Curable PE insulating compound is based on LLDPE resin, together with proper additive such as silane crosslinking agent, initiator and anti-oxidant. The compounds are made in a twin screw extruder and available in pellet form. Combination with the compound, suitable catalyst masterbatches is also supplied.
BLS XL 101/102 is a grade for upto 1.1 KVA power cables. Whereas, BLS XL 201/202 is a grade designed for upto 10 KVA power cables.
The two components, BLS 101/201 is the Silane Crosslinked Grafted compound and BLS 102/202 is the Catalyst Masterbatch. The two components required to be mixed at a ratio of 95:5 before extrusion. BLS 101/201 and BLS 102/202 are in natural colour. Colouring can be done by adding colour masterbatches externally during mixing of two components.
Maintaining suitable temperature parameters in extruder, good shine and easy processability can be achieved. Less than 1 mm thick cables need lesser dosing of BLS 102/202 Catalyst Masterbatch. It is recommended to pre-die BLS 102/202 Catalyst Masterbatch and Colour Masterbatch at 60 degree centigrade in 4-6 mm layer for 12 hours in a circulating air oven. Post extrusion curing is required, either immersing in hot water at 80-85 degree centigrade or exposing to steam in a steam chember. The curing time depends on insulation thickness.
In any case opened bag should not be stored. Intact bags should be stored in ambient temperature, i.e. 30-35 degree centigrade.in a dry place. Avoid exposure to sunlight during storage. We recommend using the product before 120 days from the date of manufacturing.
