Trial design and interpretation
Screen for large particles that can scratch or cause blockage and record the sieve opening and equipment clearance. Keep median size, coarse fraction and mixed viscosity separate. Use the same mixing procedure to assess passage through the system.
Recording Median particle size D50
Median particle size D50 (µm): Denka DAM-45 third-party typical value 42.8. Request coarse-end particle size and its measurement method. Select against the actual filling gap. Specific surface area (m²/g): Denka DAM-45 typical value: 0.2. Match adsorption method and pretreatment before comparing results.
Why do potting compounds scratch or block at equal D50?
Check the coarse tail, sieve residue and equipment clearance. Record agglomerates and viscosity before and after filtration. Thermal interface potting compounds: Disperse at equal volume fraction. Record pourable working time, mixed viscosity and thermal conductivity after cure.
What to record
- D50 method
- Coarse sieve residue
- Equipment clearance
- Blockage or scratches
