Gypsum board, gypsum board encyclopedia, what is gypsum board

2025-10-19

Gypsum board is a material made primarily from building gypsum. It is lightweight, strong, thin, easy to process, and offers excellent sound insulation, heat insulation, and fire resistance. It is one of the new lightweight board materials currently receiving significant development attention.

Q: What are the uses of gypsum board?

At the end of the 19th century, many countries began to use gypsum boards as interior partition walls. In the 1970s, China began to test and produce paper-faced gypsum sheets and hollow gypsum strips, and applied them in construction projects.

Lightweight partition walls made of gypsum sheets or hollow gypsum strips can be used to divide interior spaces. They are simple to construct and easy to fabricate and install. These walls typically use steel and wood keels as their framework and can be combined with other materials (such as mineral wool boards, waterproof coatings, and decorative surface materials) to create soundproofing, waterproofing, or high-end decorative features, depending on the application requirements.


Q: What are the characteristics of gypsum board?


gypsum board

The gypsum board uses a special paper surface, which is light and high-strength.


Features: fireproof and moisture-resistant, soundproof, heat-insulating, earthquake-resistant and heat-insulating, quick installation and construction.

Uses: Widely used in wall, ceiling and surface decoration projects of residential buildings.


The core of the board adopts high-frequency foaming technology and adds fiber filaments, which has strong nail holding power, no cracking, and good toughness; the paper surface uses high-quality and high-weight paper to increase the overall strength, which is light and strong, does not peel off, and the board surface is flat; five-alkali refractory fiber is added to give it a certain fire-resistant function.


There are many types of gypsum board

According to different functions

Divided into the following 6 types


Negative ion gypsum board has the function of releasing negative ions. According to the test of authoritative organizations, the average speed of negative ion release of negative ions by negative ion gypsum board is 2710/cm2 per second, creating a home forest oxygen bar.

In addition, it also has sterilization function, UV protection function, photocatalytic function, self-cleaning function, and antibacterial function, opening a new era of healthy home.

Seiko's formaldehyde-free gypsum board adopts German production technology and is decorated with environmentally friendly red paper. The board itself does not contain formaldehyde, and the auxiliary materials are processed through advanced technology to make it have formaldehyde-free properties. The board surface is beautifully cut on all sides, flat and smooth, and easy to process.

The waterproof formaldehyde-free gypsum board adopts double-sided green paper surface. A certain amount of waterproofing agent and silicone oil are added to the gypsum core material, and it is evenly distributed in the gypsum board body through advanced process technology. The waterproof function reaches the industry-leading level!

Home decoration formaldehyde-free gypsum board is made of building gypsum as the main raw material, with appropriate additives and fiber as the board core, and special paper as the surface processing; it has many advantages such as thermal insulation, fire and moisture resistance, sound insulation, and easy construction, and is widely used in various industrial and civil buildings.

High-strength formaldehyde-free gypsum board uses a single-sided ivory white/green paper surface. It is pressed under higher pressure and reduces water ingress, so the porosity is smaller after the slurry hardens, and it has higher strength and density.

The formaldehyde-free gypsum board paper surface uses single-sided ivory white paper, does not contain formaldehyde, is processed using world-class advanced technology, is fireproof and wear-resistant, easy to process, and is widely used in engineering decoration.
