What Is the Difference Between PP Honeycomb Panels and PP Bubble Boards?

What Is the Difference Between PP Honeycomb Panels and PP Bubble Boards?

May 5,2023
PP honeycomb panels and PP bubble boards are both types of lightweight and durable materials made of polypropylene, and have different applications in various industries. While they share some similarities, there are distinct differences between the two.

PP honeycomb panels are made using a honeycomb structure that consists of polypropylene (PP) core material sandwiched between two face sheets. The core material is typically arranged in a hexagonal pattern, resembling the structure of a beehive. This design gives the panel its exceptional strength-to-weight ratio.
PP honeycomb panels have a honeycomb core structure, which consists of a series of hollow cells. These cells are interconnected to form a strong and lightweight core.
The honeycomb structure provides excellent strength and rigidity to the panel. It can withstand high compression and shear forces while remaining relatively lightweight.
PP honeycomb panels are lightweight due to the hollow core structure. This property makes them suitable for applications where weight reduction is essential, such as aerospace, automotive, and transportation industries.
PP honeycomb panels find applications in various industries, including aerospace, automotive, marine, construction, furniture, and packaging. They are used for interior panels, partitions, flooring, doors, furniture components, and lightweight structures.

PP bubble boards, also known as PP bubble sheets or PP hollow sheets, are made from a flat sheet of polypropylene with hollow cylindrical structures, often referred to as bubbles, running through its thickness. These bubbles provide strength and insulation properties to the material.
PP bubble boards have a layered structure with hollow cylindrical bubbles running through the thickness of the sheet. The bubbles are evenly spaced and interconnected, providing structural integrity.
The air-filled bubbles in PP bubble boards act as insulators, providing thermal insulation properties. This makes them suitable for applications where temperature control is necessary, such as packaging, advertising boards, and construction.
PP bubble boards are relatively flexible and can be easily cut, folded, or shaped to meet specific requirements. This flexibility allows for easy customization and installation.
PP bubble boards are commonly used in packaging, such as protective packaging, signage, advertising boards, and temporary structures. They are lightweight, cost-effective, and provide good impact resistance.

How to choose between them?
The main difference between PP honeycomb panels and PP bubble boards lies in their core structures. PP honeycomb panels have a hexagonal honeycomb core, providing high strength and lightweight properties.
On the other hand, PP bubble boards have a layered structure with hollow cylindrical bubbles, offering insulation and flexibility. The choice between the two depends on the specific requirements of the application, such as load-bearing capacity, insulation needs, and desired flexibility.
