Samlongda Polyethylene (PE) has long been recognized as an engineering plastic that exhibits a high degree of inertness, making it attractive for use in markets such as food and beverage, laboratories, and chemical processing where leaching or permeability would present risks. Polyethylene is also one of the lower-cost plastic materials and satisfies many requirements that call for inexpensive, lightweight tubing. In fact polyethylene tubing is so lightweight, it floats. PE tubing handles a wide variety of applications ranging from potable water feed or drain lines to pneumatic or signal lines used in instrumentation.
