What material does SIERRA use to manufacture its poly tanks?
SIERRA uses HDLPE (high density linear polyethylene) to manufacture our tank line. High density linear polyethylene has good structural rigidity and impact resistance. It is resistant to a broad range of chemicals including sulfuric acid, sodium hypo chlorite, and sodium hydroxide. We also offer, for specific applications XLPE (cross-linked polyethylene). Cross-link polyethylene has excellent structural rigidity and impact resistance. It is used as an alternative to HDLPE for storing surfactants or solvent-based chemicals, or for higher service temperatures.
