Plastic balls are ideal for light-load bearings and flow control applications. Because they are quiet, plastic balls are often selected for use in office furniture, bearings, medical products, and similar applications. Plastic balls are also used extensively in flow control applications, in pharmaceutical, food processing, and chemical processing equipment.
ITI produces phenolic balls for the oil and gas industry. Phenolic balls are used in oil well completion to seal off segments of the well for fracturing. Phenolic balls are often used in the completion process are referred to as cage balls, drop balls and/or plug balls.
Plastic balls have low friction and require virtually no lubrication. They are much lighter than metal balls, and resist corrosion and abrasion very well. Compared to metals having comparable corrosion resistance, plastics are generally less expensive. Many plastics are also extremely resistant to heat. Silicone balls, for example withstand temperatures up to 600ºF, and tetraflourethylene balls withstand almost equally high temperatures.
Standard Fractional Plastic Balls
ITI is capable of manufacturing a ball from almost any plastic material. Certain plastic ball materials are more common than others. ITI regularly produces nylon balls, delrin balls, polypropylene balls, and polyethylene balls.
