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. • Sandwich skins can be melted to core • Excellent dielectric properties • Use temperatures below 200°F • Good thermal and electric insulator • Small cell sizes at high densities • Conductive grades available • Available transparent and in colors • Fire, corrosion and fungi resistant PP Polypropylene Honeycomb Supplied with or without a non-woven polyester veil for better bonding. It is also supplied with or without a film barrier under the polyester veil to limit the amount of resin consumption. • High strength to weight ratio • Thermoformable • Corrosion, fungi, rot, chemical and moistu
