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
Specifications Met: See table

Resistant to swelling when exposed to water, these balls are often used in laboratory applications.

Hollow balls float. Use them in tanks to slow evaporation and reduce heat loss.
