Enpure is manufactured from special high purity virgin polypropylene materials. No regrind material is used in the manufacturing process, thereby avoiding contamination by colorants or other materials and potential loss of physical properties due to the incorporation of heat stressed materials;The inherent abrasion resistance of natural PP allows substantial increases in life expectancy compared to other materials. In many applications, natural polypropylene out-performs other materials such as metals;IPEX piping is smooth and has a substantially lower roughness factor than metal and other materials, and since thermoplastics do not rust, pit, scale or corrode, the interior walls remain smooth in virtually any service;Our thermoplastic materials are immune to damage from naturally corrosive soil conditions as well as electrochemical or galvanic corrosion. These noncorroding properties extend service life and lower maintenance costs even in below-grade applications;Once properly selected for the application and correctly installed, Enpure products provide years of maintenance free service;IPEX Enpure natural PP has lower material and installation costs than other comparable materials such as stainless steel or PVDF
