THERMOPLASTIC RESIN PELLET FOR CLEANING SPHERE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin pellet for cleaning a sphere having a high cleaning capability and excellent its persistence in a structure having no edge to reduce an occurrence amount of a powder-like resin dust in a pellet manufacturing process or at a cleaning time of a contaminated article and a method for manufacturing the same. SOLUTION: The thermoplastic resin pellet for cleaning the sphere is formed of a thermoplastic resin. The pellet has a major axis of a length of 0.22 to 0.50 times as large as a diameter of the sphere to be cleaned and a true sphericity of 0.7 to 1.0 as a value in terms of a Wadell sphericity.
