ARM Publishes Particle Size Test Method

The ARM Education Committee has completed work on the Test Method for Particle Size of Rotational Molding Powders.

This test method uses a sieve stack and mechanical shaking device to evaluate the particle size distribution of powders for the purpose of rotational molding. Experience over many decades indicates that rotational molding powders need acceptable particle characteristics to be handleable and rotomoldable.

Thanks to our Education Committee for their hard work on this project.
