Pexidan® J/T

Low density moisture curable polyethylene compound for SAE J1128 Automotive wire applications.

Pexidan® J/T is a low density XLPE system curable by moisture and consists of a silane pre-grafted base compound A-3001 and a flame-retardant catalyst masterbatch CAT-012FR. Mixed and extruded in the proper proportions (60:40), the two components result in a material that is curable by exposure to 70-90°C hot water or even ambient moisture. Pexidan® J/T is designed to meet SAE J1128 standards for GXL, TXL and SXL type insulation. Pexidan® J/T is a RoHS-compliant system.

Curing can be done in the following ways: by immersion in hot water at 90-95°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 20 AWG wire with wall thickness of 0.015", cured in hot water (6 hours @ 95°C).
