Redispersible Polymer Powder (RDP) Redispersible Emulsion Powder (RDP) is a water soluble polymer made from ethylene-vinyl acetate (EVA) polymer through spray drying, it's designed for the construction industry to enhance the properties of dry mortar blends. Product Description Category:  Vinyl Acetate Ethylene (VAE) based polymer powder CAS: 24937-78-8 Molecular Formula: (C4H6O2.C2H4)x Introduction Redispersible Emulsion Powder  (RDP) is a water soluble polymer made from ethylene-vinyl acetate (EVA) polymer through spray drying, it's designed for the construction industry to enhance the properties of dry mortar blends. RDP is always combined with cellulose ethers  and other additives to improve the properties and performance for the cement based or gypsum based mortar, such as better water-retention,open time,better work-ability, increasing adhesion to a variety of substrate and higher flexural strength and flexibility etc.. Its technical ability to increase th...

Polypropylene Fiber PP Fiber with polypropylene  as its raw material, this fiber is produced by special technology. The products have net-like structure with many fiber monofilaments. Product Description Polypropylene fiber/ PP fiber , also known as anti-cracking fiber, PP fiber, or concrete fiber, is a high-strength bundled monofilament fiber made of polypropylene. The addition of our polypropylene fiber products to mortar or concrete can effectively control the micro-cracks of concretes or mortars caused by plastic shrinkage, dry shrinkage, temperature changes, and other factors, etc. At the same time, it can also prevent and inhibit the formation and development of cracks, thereby significantly improving the penetration resistance, impact resistance, and earthquake resistance of concretes. Our polypropylene fiber products have tensile strength and high modulus, which can help enhance the mechanical properties of high-strength concretes and improve the bond strength between ...
