The market offers a wide variety of thermal insulation mortars; common types include cement-expanded perlite mortar, cement-expanded vermiculite mortar, and various composite cement mortars. As my country advances its efforts in energy conservation and emission reduction, novel wall insulation materials have emerged. Among these, EPS (Expanded Polystyrene) granule insulation mortar has gained widespread application; utilizing a layered plastering technique, it can achieve a maximum thickness of up to 100 mm. This type of mortar is characterized by its thermal insulation, heat-blocking, flame-retardant, and durable properties.
Dry-mix mortar for exterior wall insulation offers numerous advantages. First, it exhibits high bond strength and firm adhesion, while also providing waterproofing and anti-seepage capabilities; even after prolonged use, it remains free from cracking, hollowing, or detachment. Furthermore, it possesses excellent water retention, minimal shrinkage, and strong resistance to freeze-thaw cycles and aging. Second, it facilitates thin-layer application, requiring less material and minimizing waste; this saves both time and labor, resulting in high construction efficiency. Third, it is non-toxic and odorless—posing no harm to human health—and generates no dust during application, thereby contributing to environmental protection and enabling “civilized construction” practices. Additionally, the bagged dry powder format simplifies transportation and storage; at the construction site, it requires only the addition of water and mixing to be ready for use, offering exceptional convenience and speed. Finally, the manufacturing process is straightforward, requiring no heating or complex technical procedures, allowing for the production of high-quality products at ambient temperatures.
As a professional hpmc manufacturer, Dongyuan Shengda provides high-quality Hydroxypropyl Methylcellulose (HPMC) for thermal insulation mortar, helping improve water retention, workability, adhesion strength, and overall construction performance.
