"Fireproof boards" are mainly divided into the following three categories. You need to first clarify which one you are referring to

High-pressure decorative fireproof board (the most common narrow sense of fireproof board)

This is the most classic and most commonly referred to as "fireproof board" material. It is very thin by itself (0.6mm-1.5mm) and needs to be adhered to the base material for use.

Composition and process: It is made by curing and pressing multiple layers of special paper impregnated with melamine and phenolic resin under high temperature and high pressure.

Features

The surface effect is excellent: there is an extremely rich selection of textures such as color, wood grain, stone grain, and metal, with a high degree of simulation.

Outstanding physical properties: wear-resistant, scratch-resistant, heat-resistant, and resistant to chemical corrosion.

It is not absolutely non-flammable: It has excellent flame-retardant performance. When exposed to open flames, it will carbonize but is not easy to burn.

2. Mineral wool board/gypsum board (fireproof board for building partition walls and ceilings)

This type is non-combustible A-level material used in building fire protection systems, mainly for partition walls and ceilings to enhance the fire resistance rating of buildings.

Components: The main components are inorganic substances such as mineral wool and gypsum.

Features

Absolutely non-combustible: Meets the national A-level non-combustible standard.

Sound insulation and heat insulation: It has excellent heat preservation and sound insulation effects.

General decorative effect: The surface is mostly white or has simple holes and textures, and usually requires subsequent spraying for decoration.

3. Fireproof base material board (board with a certain fire resistance rating itself)

This type of board itself has a certain thickness and structure. Its base material has undergone special treatment and has reached a certain fire resistance grade.

Common types

Fireproof particle board/fireproof density board: Fire retardant is added to the wooden base material.

Magnesium oxide board: Made of inorganic substances such as magnesium oxide and magnesium chloride, it has excellent fire resistance but is relatively heavy.

Features

It is a structural material in itself: it can be directly used to make cabinets and partitions.

There are various fire resistance grades: When purchasing, it is necessary to confirm its fire resistance test report and grade.

To avoid confusion, the following selection guide will mainly focus on the most common type, the "high-pressure decorative fireproof board".
