HDX is an ultra-high molecular weight resin of high density polyethylene.

BioTherm HDX (high density extrusion) is our durable polyethylene tubing solution commonly used for in slab and floor heating. Manufactured from a ultra-high molecular weight resin, HDX tubing is extremely tough and meets stringent ASTM testing standards for quality. It's made from a distinct red color, so you know you are getting true HDX tubing. Also offered is our GreenPEX with E-Beam cross-linking for increased durability, commonly used in institutional environments, available with or without oxygen barrier.
