Influences Of HPMC On Gypsum Based Products

Gypsum has long been used in the construction industry due to its versatility and broad applicability. It is non-toxic, fire resistant, non-combustible, and very workable and user friendly, allowing its users to create aesthetically pleasing finishes. Gypsum also has very good thermal and acoustic properties.

The most common uses of Gypsum products in the construction industry include gypsum premanufactured wall and gypsum ceiling plasterboards, gypsum self-leveling screeds, gypsum hand or machine applied plasters, gypsum trowelable compounds, gypsum joint fillers, and gypsum adhesives.

The properties and performance of Gypsum can be significantly improved using relevant additives. SLEOCHEM cellulose ether products Hydroxypropyl Methylcellulose (HPMC), Hydroxyethyl Methyl Cellulose (HEMC) are specially formulated high-performance additives that can transform basic Gypsum based cement products into superior construction materials with sought-after properties.

Gypsum Trowelable Compounds
Different from the sand and cement method traditionally used in construction, Gypsum trowelable compounds use gypsum as the basic material and high molecular polymer as the cementing material, exhibiting good compatibility and strong adhesion with the common construction surfaces.

SLEOCHEM Hydroxypropyl Methylcellulose (HPMC), Hydroxyethyl Methyl Cellulose (HEMC) are formulated to offer these improvements to Gypsum trowelable compounds:

Good water retention and extended working time
Optimized product consistency and rheology
Reduced lump formation
Improved adhesion and sliding resistance
Gypsum Joint Fillers
Gypsum joint fillers are used for filling the joints in between Gypsum plasterboards or fiberboards.

SLEOCHEM Hydroxypropyl Methylcellulose (HPMC), Hydroxyethyl Methyl Cellulose (HEMC) are formulated to offer these improvements to Gypsum trowelable compounds:

Improved joint strength and flexibility, reducing the risk of joint splitting under expansion and contraction
Good water retention and extended working time
Optimized product consistency and rheology
Reduced lump formation
Improved adhesion and sliding resistance
