What Is PP Hollow Board?
PP Hollow Board, also known as Polypropylene Hollow Sheet, is a lightweight plastic sheet produced by extrusion technology. The internal hollow structure provides excellent rigidity while reducing material weight.
This unique design makes PP Hollow Board suitable for applications requiring both strength and portability. Unlike paper-based boards, it does not absorb moisture, making it ideal for humid or outdoor environments.
Because polypropylene is chemically stable and highly durable, PP Hollow Board performs well even under demanding industrial conditions.
