Product Description
K38-20-138 is a natural medium density polyethylene resin designed for pipe extrusion and small diameter tubing applications. It exhibits excellent long term stress life and environmental stress crack resistance. When the product is extruded in combination with an INEOS approved black masterbatch,the resulting pressure rated formulation known as K38-20-123 has NSF Standard 14 certification, complies with ANSI/NSF Standard 61 health effects requirements and is listed with the Plastic Pipe Institute as PE 2708 (formerly PE 2406).
