SiPOR-50 is delivered in form of solid, free flowing pellets, containing liquid VSS-50, a fully stabilized cross-linking system developed for crosslinking polyethylene low- and medium-voltage cooper cables using one-step process. Our special carrier technology has made it possible to manufacture this highly concentrated batch successfully.
SiPOR-50 is a silicone Masterbatch of VSS-50 in different carriers, which provides significant advantages to your compounding operation:
Provide excellent mechanical properties, outstanding chemical resistance.
Special stabilizers prevent premature polymerization of the grafting agent and provide excellent aging properties of crosslinked polyethylene.
A hazardous, highly reactive liquid supplied in the form of dry, free flowing granules.
Safe and accurate dosing and dispersion in continuous compounding operations without the need of expensive injection Pumps.
Linear extruder output, no slipping effect or squeeze out phenomenon of the silane.
With an appropriate resin, insulated copper cables crosslinked with SiPOR-50 masterbatches can meet the IEC aging test of 7 days at 135°C.

This vinyl silane is packaged with 10Kg aluminum foil bags (outside carton box). A period of at least 6 months from date of manufacture can normally be expected. Packages already opened should be used up immediately.
Store under cool and dry conditions. Due to the decomposition temperature of the dry silane above 70°C, the masterbatch should not be stored or shipped at temperatures above 55°C, since some degradation of product may occur. Direct sunlight exposure and temperatures below 0°C should also be avoided.
