Plastics are increasingly being used to replace other materials like bronze, stainless steel, aluminum and ceramics. The most popular reasons for switching to plastics include:

	Longer part life
	Elimination of lubrication
	Reduced wear on mating parts
	Faster operation of equipment/line speeds
	Less power needed to run equipment
	Corrosion resistance and inertness

With the many plastic materials available today, selecting the best one can be an intimidating proposition. Here are guidelines to assist those less familiar with these plastics.
