Plastic Balls

We manufacture industrial plastic balls for various applications and consumer products, including polypropylene balls, teflon balls, nylon balls.

Low load applications and flow control devices use industrial plastic balls. Colored plastic balls are used for identification purposes in many medical applications. Also, plastic balls offer excellent fatigue and corrosion resistance, impact strength and in many cases natural lubricity. Hartford Technologies offers a complete line of FDA-approved plastic balls in materials including nylon, Delrin and other engineered plastics.

Furthermore, all plastic balls are available for immediate delivery.
