LDPE Balls are low-density polyethylene spherical particles in Goodfellow's range of polymer products. Available in 2 variations of diameter and surface finish. LDPE is known for properties like chemical resistance, flexibility, and toughness. These LDPE balls can be used in applications like flow visualization experiments, calibration of particle size analyzers, and modeling of granular flow systems. With their precise dimensions and uniformity, the LDPE balls are well-suited as tracer particles across industrial and scientific uses.
