Gypsum plaster advantages
Gypsum plaster is also called POP, it’s white cementation produced by dehydrating mineral gypsum, partially or completely. Often added with decelerators or hardeners. Employed with water in a plastic state, it sets and hardens by the chemical reunification of gypsum and water.
- Gypsum is a readily available raw material, not hard to find
- Easy and accessible. Fast drying, reduces water consumption
- Lower thermal conductivity, saving energy for heating or cooling
HPMC for gypsum plaster
WOTAI Chemical is a professional and reliable HPMC manufacturer and supplier. We provide you with the highest quality of HPMC. For gypsum plaster as well as other applications. The construction industry is constantly using new materials to improve building products’ quality and overall performance. Gypsum plaster is one of the latest materials, which is now widely used. However, the most important factor is HPMC as the basis of gypsum plaster, especially in terms of stability and thickening.
HPMC has great water retention power. This prevents cracking and enhances the overall appearance of the plaster. It also improves surface uniformity, lubricity and adhesion when applied to wall putty and other construction areas. Beyond that, of course, if you want to increase the tensile strength of gypsum plaster, HPMC is the right option for you. It can act as an interfacial agent. In other words, it can improve the bending strength of gypsum and increase the bonding strength. All of the above factors make HPMC a necessary part of gypsum plaster that every construction worker must have.

HPMC advantage in gypsum plaster
Good water retention and thickening effect
It is well known that cement reacts with water and cracks form when it dries. Gypsum plaster added HPMC, with water retention and thickening effect. There are no cracks after the surface dries out.
Better performance, better workability
Gypsum plaster does not require as much labour as mortar plaster to complete or achieve a perfect smooth effect finishing. It reduces labour and creates visually appealing rooms at the same time.
Durable and fire resistance
Gypsum plaster is light and durable, which means that its use adds very little weight to the building. It ensures the frame is able to cope with natural disasters and maintain its shape over a long time. In addition, gypsum plaster is highly resistant to fire and can hold the fire for up to 3 hours.

Gypsum is a mushy substance that becomes hard when it dries and is used to paint walls, ceilings, partitions, and other areas. Plaster plastering is an old building technique.
Gypsum plaster, though light in weight, is very durable, and the walls are tough and strong. Plaster plate has a wide range of uses, any form of decoration needs to be used.
Under normal circumstances, the expected service life of gypsum plaster is more than 50 years. Apart from that, gypsum’s unique fire-resistant help protect buildings or reduce damage in the event of a fire.
