EVA

When VAE is mixed with sand slurry, many properties are improved, but the properties of mortar are also different due to the amount of emulsion mixed in mortar. According to research, from the comprehensive point of view of performance and economy, it is considered that the P/C (polymer weight/cement weight) value is between 0.1 and 0.4.   Increase mortar strength: The fluidity (flow value) of the mortar increases with the increase of the amount of emulsion added, and can rely on mixing with the emulsion to reduce the amount of water, so as to obtain a dense hardened substance, and can increase the strength, so that the shrinkage rate and water absorption decline. Improve the brittleness of mortar: When VAE emulsions are mixed into it, vibration-absorbing polymer particles fill the cement Spaces, thus improving the impact resistance of the mortar. Improve chemical resistance: The mixed VAE emulsion can improve the acid resistance of the mortar and prevent the corrosion of salt water, machine oil, ammonia, methanol and other chemicals.   The use of synthetic resins can improve the strength and adhesion of concrete, mortar, etc: The synthetic resin solution is applied to the surface of the original concrete or mortar, and then the surface is covered with new concrete or mortar, which can eliminate the "rough work" process. At present, polyvinyl acetate emulsions and styrene-butadiene rubber latex are commonly used, and VAE emulsions have greater bond strength than these two emulsions. Pure mortar has no bonding strength for wood, metal, plastic, etc., and only when the polymer is mixed in, the mortar can bond with wood, etc. High strength can be obtained by curing in the air (it is not necessary to spray water onto the poured mortar). If the hydration reaction of cement products is not sufficient, then it cannot get the inherent strength, so if the mortar is cured in the air, then it is brittle and easy to crack. If VAE emulsions are mixed in, the strong hydration force of the emulsions prevents the mortar from losing water too quickly, thus providing the moisture needed for cement curing.   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.

VAM stands for Vinyl Acetate Monomer. It is a key raw material used in the production of various polymers and copolymers. Vinyl acetate monomer is a clear liquid with a distinct odor. It is primarily derived from the reaction between acetylene and acetic acid.   VAM is widely used in the manufacturing of polyvinyl acetate emulsions, which find applications in adhesives, paints, coatings, and textiles. The copolymerization of VAM with other monomers, such as ethylene, creates ethylene-vinyl acetate (EVA) copolymers, which have excellent flexibility, adhesion properties, and low-temperature resistance. EVA is extensively used in various industries, including footwear, packaging, wire and cable insulation, and solar cell encapsulation, among others.   The versatility of VAM as a building block for different polymers and copolymers makes it a crucial material in the chemical industry. Its unique properties, such as good adhesion, film-forming capability, and chemical resistance, contribute to the wide range of applications it offers.   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.

No, Ethylene Vinyl Acetate (EVA) is not the same as Vinyl Acetate-Ethylene (VAE). While both EVA and VAE are copolymers of ethylene and vinyl acetate, they have different structures and properties.   EVA is a copolymer of ethylene and vinyl acetate, where the vinyl acetate content typically ranges from 5% to 50% by weight. It is a flexible, rubbery material commonly used in various applications such as footwear, packaging, and solar cell encapsulation due to its excellent flexibility, low-temperature toughness, and UV resistance. VAE, on the other hand, refers to a different type of copolymer formed by the polymerization of vinyl acetate and ethylene. In VAE, the vinyl acetate content is generally higher than in EVA, typically ranging from 10% to 60% by weight. VAE is often used as a binder or adhesive in construction materials such as paints, coatings, adhesives, and textiles.   So, while both EVA and VAE are copolymers of ethylene and vinyl acetate, they have different compositions and applications.
