TPPL Wire and Cable Compounds

Product Name : TPX 101 and TPX 210

Description: TPX 101 is moisture curable Silane XLPE compound for Low Voltage Power Cable Insulation. It is designed to be used together with our catalyst/additive master batch TPX 210 added @ 5 wt. %. Extruded combination can be crosslinked by exposed to low pressure steam, immersed in hot water or in ambient conditions.

These temperatures can slightly modify depending on extruder type, tool design and test results.

LD ratio : 24:1
Compression ratio : 2.1 to 2.9
Screen pack : 40/60/40
DDR : 1.5 to 2.4
Screw Cooling : 70 OC
Color Master Batches : Use only LDPE/ EVA based color MB @ 1%

Drying:

For better performance, Dry catalyst MB TPX 210 and color masterbatches may be dried at 65 OC for 4 hrs. Not recommended to dry TPX 101

Storage & Handling

TPX 101 & 210 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.
