In gypsum (plaster) products, the focus is on water retention, retardation and lubrication. Different gypsum has different effects on product performance, so thickening, water retention, and retardation determine the quality of gypsum building materials.
The role of HPMC in gypsum products
• Shrinkage resistance, hollow resistance and crack resistance
• Good sag resistance
• Good workability
• Good water retention
• Environmental protection
Moreover, RDP powder is used in gypsum-based products to improve their water resistance, adhesion, and strength
