Low-Density/High-Density Polyethylene...What Is the Difference?
Low-density polyethylene (LDPE) is the most widely used plastic for lab apparatus. It is translucent to opaque and tough enough to be virtually unbreakable—but at the same time quite flexible. LDPE is resistant to a very broad array of chemicals at ambient temperatures. Strong oxidiz- ing agents are the main exception. Strong oxidizers will, over time, cause the plastic to craze and crack. LDPE can handle temperatures at or near 80 °C, but not above.
High-density polyethylene (HDPE) is sometimes called linear poly- ethylene. This plastic is always more opaque than LDPE, but in general HDPE has better chemical resistance characteristics than LDPE. High- density polyethylene can also handle temperatures around 110 °C.
How can you tell the difference? LDPE will float in a 50/50 (volume) mixture of 95% ethyl alcohol and water. HDPE will sink.
Avoid storing strong oxidizing chemicals in any plastic container. Glass is your best package choice for prolonged storage of these chemicals.
