waterproof light weight polypropylene honeycomb
Product Description
Polycore polypropylene (PP) honeycomb reportedly provides greater strength-to-weight ratio than traditional polyaramid or aluminum honeycombs. The cells of the PP honeycomb are essentially circular rather than hexagonal and are fused together rather than glued. The recyclable honeycomb can be thermoformed and cut to shape easily has energy-absorbing and sound- and vibration-damping properties, and is resistant to fungus, rot, chemicals and moisture.
Honeycomb core cell diameter from 8mm to 12mm,most commonly adopted is 8mm,10mm,12mm can be made according to client request. Honeycomb core can be directly apply into air purify and other fields without tissue on both sides. Core cell wall thickness can be selected if clients have special requirement. Core cell 8mm density is 88kgs/cubic meter. Core cell 12mm density is 75kgs/cubic meter.
PP honeycomb sheet laminated with polyester tissue on both sides. This allow better bonding of the honeycomb to different surface panel. In addition to the tissue, honeycomb can laminated with a layer of PP film . The film under the tissue acts as a barrier to prevent resin leaking into the core thus save resin consumption in next assembly process Besides there is more stiffness plastic sheet with more thicker tissue.
Light weight, high compressive strength, anti-water, anti-humidity honeycomb can be used as a core structure in the transportation fields such as aerospace, aircraft, boat, yacht, van, marine, automotive, truck, rail, In this application, honeycomb can cut down body weight, increase speed, save energy, whilst providing strength and lessen shakiness. For example: 20mm thickness PP honeycomb weight is only 2.2-2.4kgs/square meter but its compressive strenth high to 2.0Mpa.
So now in European, American, Pacific Ocean countries, south east Asia,China there are more and more fiberglass boat/yatch select PP honeycomb in their boat making. PP honeycomb sheet widely used in deck,hull,partition wall, door,canopy, floor,furniture in boat. In China coastguard vessel adopt PP honeycomb to replace of plywood the vessel speed improved to 70kts (before the speed only 20kts), so now most of such vessel has change to such new technology.
