LDPE Low Density Polyethylene
Low density polyethylene is used extensively for piping, because of its ease of handling and fabrication on the site. The chemical resistance of the product is outstanding, although not as good as high density polyethylene or polypropylene.
Fusion welding of the material is readily accomplished with appropriate equipment, and installations of piping made in this manner are the least expensive and most durable of any material available for waste lines, water lines, and other miscellaneous services not subjected to high pressures or temperatures. The upper temperature limit for the material is 60 °C.
The product can be compounded with a wide variety of materials to increase strength, rigidity, and other mechanical properties. Chemical resistance is excellent within the temperature region allowed by the material. It is now available in a fiber reinforced product to further increase the mechanical properties. The low modulus of the material must be recognized to provide successful installations. Straight-chain hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, and strong oxidants must be avoided. All other materials are handled readily by the product.
Stress cracking can be a problem without careful selection of the basic resin used in the product or proper compounding to reduce this effect. Compounding of the product is also recommended to reduce the effect of atmospheric exposures over long periods.
