Polywvinyl Alcohol Purchase

Redispersible emulsion powder is a modified emulsion powder obtained by spray drying of a binary or ternary copolymer of vinyl acetate and tertiary vinyl carbonate -VeoVa or ethylene or acrylic ester, which has good redispersibility and is re-dispersed into emulsion when it is in contact with water, and its chemical properties are exactly the same as the initial emulsion. After mixing with the water in the mortar, it emulsifies and disperses in the water to form a stable polymerization emulsion. After dispersing in water, the water evaporates, forming a polymer film in the mortar after drying, improving the performance of the mortar. Different dispersible latex powders have different effects on the dry mortar. 1. Improve the impact resistance, durability and wear resistance of mortar The rubber powder particles fill the cavity of the mortar, the densification of the mortar is increased, and the wear resistance is improved. Under the action of external forces will produce relaxation and not be destroyed. The polymer film can exist in the mortar system for a long time.   2. Improve the bonding strength and cohesion of mortar As an organic binder, dispersible emulsion powders provide high tensile strength and bonding strength on different substrates. It plays a very important role in the adhesion between mortar and organic materials (molded plates, extruded plates) and smooth surface substrates. The film-forming polymer rubber powder is distributed in the whole mortar system as a reinforcing material to increase the cohesion of the mortar.   3. Improve the mortar's weatherability, freeze-thaw resistance and prevent mortar crackingThe RDP emulsion powder is a thermoplastic resin adhesive powder with good flexibility, which can make the mortar cope with the external cold and hot environment changes and effectively prevent the mortar from cracking due to the change in temperature difference.   4. Improve the hydrophobicity of mortar and reduce water absorptionThe RDP emulsion powder forms a film in the mortar cavity and surface, and the polymer resin film will not disperse twice after encountering water, preventing the invasion of water and improving the impermeability. Enhanced dispersible adhesive powder with hydrophobic effect has better hydrophobic effect.   5. Improve the bending strength and flexural strength of mortar The polymer film formed by dispersible emulsion powder has good flexibility. The film is formed in the gap and surface of cement mortar particles to form a flexible connection, so that the brittle cement mortar becomes elastic. The mortar added with dispersible emulsion powder has much better tensile and flexural properties than ordinary mortar.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com   ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
