High density moisture curable polyethylene compound for hot and cold water plumbing pipe. Suitable for SDR 9 pipe applications in continuous service at operating conditions of 140°F and 80 psi.
Pexidan® L/T (including L/T Eclipse) is a high density PEX System consisting of a silane grafted base-compound A-1001 and a catalyst masterbatch CAT-003. When mixed and extruded in the proper proportions, the two-component system results in a material that is crosslinkable by exposure to moisture or by immersion in hot water at 90-95°C. Pexidan® L/T is listed by NSF International to Standards 14 and 61 and to Canadian Standards Association standard B137.5. NSF certification to ASTM F 876 and ASTM F 2023 testifies to its superior resistance to oxidation by hot, chlorinated water. Pexidan® L/T is permitted to be used in domestic continuous re-circulation systems and is listed by NSF as a NSF-pw CL5 / PEX 5006 material.
Curing can be done in the following ways:
by immersion in hot water at 90-95°C
by exposure to low pressure steam
In all cases curing time depends on pipe wall thickness, temperature, relative humidity and any packaging used.Typical values reported above (except MFR) are obtained from samples cured in hot water (6 hours @ 95°C).
