TPX 102 and TPX 212BK (Silane XLPE Black Compounds for low voltage overhead power cable (ABC) Insulation

Description: TPX 102 is moisture curable Silane XLPE compound for low voltage crosslinked overhead (ABC) cable insulation or weather service drop cable insulation.. It is designed to be used together with our catalyst, additive & Carbon Black master batch TPX 212BK added @ 6 wt. %. to impart long term thermo-oxidative and photo-oxidative degradation resistance to the finished cable and is crosslinked by exposed to low pressure steam, immersed in hot water or in ambient conditions.

Compression ratio : 2.1 to 2.9
Screen pack : 40/60/40
DDR : 1.5 to 2.4
Screw Cooling : 70 OC

Drying:

For better performance, Dry catalyst, additive & CB MB TPX 212 may be dried at 65 OC for 4 hrs. Not recommended to dry TPX 102

Storage & Handling

TPX 102 & 212BK must be stored unopened in a dry & stable temperature environment for optimum performance. A temperature range of 10 oC to 45 oC is recommended. The material must be used within a short time after exposure to humidity in order to minimize the risk of scorching during extrusion. Compound should be used directly from its packaging.

Shelf Life

Under ideal storage conditions a shelf life of more than 6 months can be expected.
