Working with Polypropylene Honeycomb Core PP-HC-150
Is Polypropylene Honeycomb Core easy to machine?
Cuts easily with band saw, hot knife, CNC router or water jet; keep tools sharp and feed fast to avoid melt smearing, and support the core to prevent cell crushing.
Can Polypropylene Honeycomb Core be welded?
Cell walls are thermally weldable (hot-plate, ultrasonic, hot-air) to PP skins; no solvent bonding — PP cannot be solvent-cemented.
Can Polypropylene Honeycomb Core be formed, bent or molded?
Core is heat-formable/crushable to curves and can be co-pressed with PP-GF or thermoplastic skins at 170–200 °C; avoid dwell above 150 °C or the cell walls collapse.
What surface finishes work on Polypropylene Honeycomb Core?
Non-polar surface must be corona/flame/plasma treated or supplied with nonwoven scrim before PU, epoxy or PSA bonding; no painting or plating of the core itself.
Polypropylene Honeycomb Core chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
