PC Honeycomb Core Strengthening
A non-conductive honeycomb shaped PC (polycarbonate) composition exhibits a unique cell structure. The core has 3 orientations vs. the 2 orientations common with other honeycomb, making its properties more uniform. Each cell has a tubular form and is inherently stable.
Features:
- Excellent dielectric properties Good thermal and electric insulator
- Conductive grades available
- Heat isolation Moisture, fungi and Corrosion resistant
- Sandwich skins can be melded to core
- Effective use temperatures range -40° to 230° F (-40--110℃)
- Small cell sizes at high density configurations
Applications
- Ideal for low temperature settings such as wind tunnels and refrigeration units
- Solar water heaters and other water equipment
- Sandwich cores
- Radio transmission tower or antennae cover
- Skylights
- Energy absorbing structures
- EMI/RFI shielding
