Product Description
K38-20-188 is a natural, UV stabilized, medium density polyethylene resin designed specifically for use with an approved INEOS yellow masterbatch to produce pipe or tubing for natural gas distribution. The resulting formulation, known as K38-20-160, is recognized by the Plastics Pipe Institute as havinga PE 2708 (formerly PE 2406) and PE 80 rating. It exhibits excellent long term stress life and outstandingenvironmental stress crack resistance.
