PP (polypropylene) is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of only 0. 90~0. 91g/cm³, which is one of the lightest varieties of all plastics. It is particularly stable to water, and its water absorption rate in water is only 0.01%.


The Characteristics of Polypropylene are Reflected in:
- Lightweight: Polypropylene honeycomb has a lower density, making it ideal for lightweighting.
- Rigidity: Although the polypropylene honeycomb core is lightweight, it has a high resistance to distortion. It can withstand large deformations and restore its structure when it is impacted or vibrated.
- Waterproof: Polypropylene is not hydrophilic, does not rot easily, and can maintain stable performance for a long time in humid or seaside areas.
- Recyclable: Polypropylene is recyclable, which greatly reduces resource waste and is conducive to sustainable development.

PP Honeycomb Sandwich Panels
The main use of polypropylene honeycomb core is to make lightweight and high-strength polypropylene honeycomb panels. Polypropylene honeycombs can be laminated with other materials through adhesives or thermal lamination to form composite panels with different functions.
