The main application of polypropylene honeycomb panels (PP honeycomb panels) is as the core material of various composite panels. Its structure is composite a layer of polyethylene (PE) non-woven fabric on both sides of the polypropylene honeycomb core. Limited by material characteristics, it cannot meet the requirements of flame retardant grade. However, by using a new process to add high-quality halogen-free flame retardants, the flame retardant properties of plastic honeycomb panels can be achieved.
What are halogen-free flame retardants?
Halogen-free flame retardant additives are mainly based on phosphorus compounds and metal hydroxides. These two types of compounds are non-volatile do not produce corrosive gases when burned, and are called pollution-free flame retardants.
How to make halogen-free flame retardant polypropylene plastic honeycomb panels?
The structure of the non-woven composite honeycomb panel is PP honeycomb core covered with isolation film and non-woven material. The flame retardant of the polypropylene honeycomb panel can be achieved by evenly spraying the bromine phosphorus compound flame retardant on the surface of the non-woven material. The honeycomb core is composited with non-woven fabrics with high-quality flame retardants added to the top and bottom.
Application fields of flame-retardant plastic honeycomb panels
Honeycomb core material can be used alone or used to make sandwich structure composite materials. It has been widely used in transportation, construction and other industries, such as various partitions, floors, etc. of various vehicles (trains, cars, subways), ships, etc. Siding panels, hatches, roof panels, etc. In the construction industry, it can be used to manufacture exterior walls of high-rise buildings, indoor partitions, and body panels of mobile homes. It has great development prospects in the construction industry. Honeycomb cores can also be used to develop various secondary products. Halogen-free flame-retardant honeycomb panels have good flame retardancy and will not produce toxic gases when burned. They are safe and convenient to use and suitable for market promotion.
