PP(Polypropylene) Honeycomb Core
一. NTRODUCTION
PP Honeycomb is a new construction material, which is made of Polypropylene based on honeycomb bionic principles. It has many remarkable advantages like light-weight, high compressive strength, waterproof, moisture-proof, corrosion resistant and environmentally friendly etc. PP Honeycomb can extensively used to replace traditional materials, and it can be widely used in yacht, passenger carriage body, high-speed train, aerospace, glass steel, large storage tank, building materials, decoration materials and other manufacturing.
一. FEATURES
1. Light weight, high compressive strength
2. Excellent corrosion resistance, can stop the erosion of chemicals, seawater etc..
3. Excellent waterproof and moisture-proof performance
4. Excellent sound insulation performance, can effectively attenuate the sound
5. Excellent compression and shock resistance, can absorb the external force, reduce impact and collision damage.
6. Excellent Insulation performance, can effectively guarantee the relatively stability of the internal temperature
