Polypropylene Balls
- Color: Semi-Clear White
- Max. Temperature:
Solid Balls: 180° F
Hollow Balls: 220° F - Tensile Strength: 2,900-5,070 psi (Poor)
- Impact Strength: 0.9 ft.-lbs./in. (Poor)
- Hardness: Rockwell R99 (Hard)
- For Use Outdoors: No

Calibration Kit for Metal-Detectable Plastics
Made with metal additives, these balls test the sensitivity of food-processing metal detectors. They’re often used to calibrate metal detectors to find metal-detectable plastic tools that have fallen into a batch. To calibrate your metal detector, run different balls through the line—the smaller the ball, the more sensitive the detector must be to recognize it. Since they’re spheres, their orientation won’t affect a metal detector’s ability to register them. These balls help you comply with Hazard and Critical Control Point (HACCP) programs for food safety. They’re FDA compliant for direct contact with food. Balls are autoclavable, so you can sanitize them with steam.
