Low density moisture curable polyethylene compound for low voltage building wire insulation (CSA RW-90, RWU-90, AC-90, TECK-90).

Pexidan® R/T is a low density XLPE system curable by moisture and consists of a silane pre-grafted base compound A-3001 and a catalyst masterbatch CAT-009 (Sioplas method). Mixed in the proper proportions (95/5) the two components result, after extrusion, in a material curable by exposure to hot water at 70-90°C or even ambient moisture. Pexidan® R/T is listed with the Canadian Standards Association for use in RW-90 and RWU-90 XLPE applications and rated to -40°C. Pexidan® R/T is RoHS-compliant.

Additional Information	Nominal Value	Unit	Test Method
Curing can be done in the following ways: by immersion in hot water at 70-90°C by exposure to low pressure steam ambient atmospheric moisture In all cases curing time depends on wall thickness, temperature, relative humidity and quantity of wire on the reel.Typical values reported above (except MFR) are obtained from 14 AWG solid conductor samples with a 30-mil wall, cured in hot water (6 hours @ 95°C).
