PP honeycomb panel, light weight, stiffness strength ratio, waterproof, density perfect.
Application in widly for building, boat, yatch, FRP project and so on
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.
Honeycomb sheets are used in the fabrication of lightweight structures. The core material is typically ′sandwich′ with plywood, aluminium, fiberglass, steel, granite, paper and other solid surface materials, etc. To attach the surface material to the honeycomb sheet, a bonding adhesive can be used or the materials can be laminated with polyester or epoxy systems. For example, if select plywood as skin material, PP honeycomb as core material, one kind of resin or glue which is familiar with wood at same time it′s familiar with plastic material will be work to laminate plywood with PP honeycomb. In a similar way, if select fiberglass as skin material, PP honeycomb as core material, one kind of resin which is familiar with fibergalss at same time familiar with plastic material will workable to laminated fiberglass with PP honeycomb. Now most of client select fiberglass as skin material, epoxy or unsaturated resin as adhesive to laminate on PP honeycomb sheet. The resultant honeycomb panel results in one of the highest strength to light weight available.
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 and material handling, In this application. Honeycomb can lighten bare weight, boost velocity, save fuel, whilst reinforce strength and dampen vibration.
In the construction fields such as architectural, port, bridge, recreation, partition, ceiling, floor, wall, in this application, honeycomb can speed up project process, dampen sound pollution, save energy cost.
In special fields such as military, medical, oil tank cover, Equipment, electronic, pharmaceutical, food, consumer, trailer and a variety of other composite structures. In this application, honeycomb can provide special property to cater to special requirement such as electronic or Magnetics penetration, anti-chemical corrosion, anti-fire, anti-water, cleanness and others.
For example: 20mm thickness PP honeycomb weight is only 2.2-2.4kgs/square meter but its compressive strength high to 2.0Mpa.
Polycore supply dimension 1200*2400mm, 1220*2440mm, 1150*2300mm, width within 1250mm, length within 3000mm. Thickness from 4mm to 200mm. Common thickness in practice from 8mm to 60mm.
