CPT Polypropylene Honeycomb core has a unique cell structure that gives it a high strength to weight ratio. It is resistant to corrosion, fungi, rot, chemicals and moisture. It also exhibits good vibration and sound dampening. These features and its mid-range price point make polypropylene honeycomb ideal for transportation, structures, construction, and marine applications.
CPT Aluminum Honeycomb is a lightweight core material offering excellent strength and corrosion resistance. Aluminum alloy foil is bonded together and expanded to form a cellular honeycomb shape that has high compression and flexure strength. The extremely tight tolerances allows for composite panel lamination in high tech applications where ultra flat and precision panels are required. Also suitable for transportation, structures, architectural and construction applications where flammability is a concern.
CPT Insulated foam cored panels offer excellent thermal properties for applications when temperature control is important. Foam cores are available in different chemical formulations depending on the performance features required for the application. Foam cored panels can be made to be very lightweight and can be cost efficient. Suitable applications include transportation, construction, marine, and high tech.
CPT Paper Honeycomb is a relatively high strength, low weight more material with good thermal stability. The paper honeycomb can be coated to make it resistant to heat and water intrusion. Paper honeycomb composite panel applications include structures, transportation, and marine.
