Hollow plastic sheets are made of thermoplastic materials such as polypropylene and are commonly used in advertising, packaging, and as sunshade and thermal insulation materials in the construction industry. These hollow plastic sheets feature a hollow structure with a regular patterned textured outer surface and a grid-like interior. This unique design offers the following advantages:
1. Lightweight: The hollow plastic sheet has an empty internal structure, making it lightweight and easy to handle and install.

2. Excellent Insulation: The air or foam inside the hollow plastic board offers good insulation properties, effectively preventing heat conduction.

3. Excellent Waterproof: The hollow plastic sheet is made of materials like polypropylene, offering superior waterproof properties.
4. Strong Corrosion Resistance: The hollow plastic board material features anti-corrosion and acid/alkali resistance.

5. Easy Installation: Hollow plastic sheets can be cut and bent to suit requirements, making installation relatively simple.

6. High Durability: The material of the hollow plastic board is of high strength and excellent durability, ensuring long-term use.
Due to the hollow plastic board's aforementioned advantages, it is widely used in advertising, packaging, construction, and highway guardrails.
