Supplier particle library

Know what goes into the material.

Compare supplier references from 3M, Potters and Trelleborg. Every entry separates reported properties from modelling support. Hollow microspheres, solid beads and finished buoyancy foams are different materials.

Reference inclusion ≠ a validated prediction

Ten legacy grade identifiers remain in the existing model. Reference-only entries cannot be selected for simulation. Particle crush pressures use different survival criteria and protocols; none is a finished-foam strength or depth rating. Historical references are not procurement specifications.

What would make another grade usable?

Confirm the exact current grade, density method, size distribution, surface treatment and relevant test protocol. Then connect it to the partner’s resin, manufacturing process and independent batch measurements. A supplier reference alone does not provide all inputs or establish model accuracy.

Five stored Eccospheres literature rows retain an uncertain historical supplier/grade label. They have not been mapped to any modern Trelleborg grade.
