Product characteristics
Versatility: Modified VAE emulsions have a variety of functions, such as excellent bonding properties, good water and alkaline resistance, excellent weather resistance, etc.
Water: The emulsion with water as the medium, with environmental protection, pollution-free characteristics, in line with the development trend of modern green chemistry.
Modification: Through specific modification technology, such as adding functional additives, adjusting the molecular structure of the polymer, etc., the emulsion can further improve its versatility and performance on the basis of maintaining the original properties.

Modified multi-functional water-based vinyl acetate-vinyl copolymer emulsions (e.g., KEY 289 PVA emulsions) for the production of high strength, low water absorption grade A2 fireproof aluminum-plastic panel core materials have the following key characteristics and advantages:

Product Description:
The modified multi-functional water-based vinyl acetate-vinyl copolymer emulsion is a special emulsion suitable for A2 grade fireproof aluminum-plastic board core material.
It has medium to high solid content and low viscosity, allowing the addition of medium filling amount of filler.
Product features:
It can be used in the application of powder such as calcium carbonate, aluminum hydroxide (ATH), magnesium or bromine flame retardants requiring moderate filling.
No organic solvents and plasticizers are added in the production process.
It can be dried at high temperature without Browning.
The bonding property of the filler is very good, and the core material produced has high peeling strength after synthesis.
Scope of application:
It is suitable for the production of A2 grade fireproof aluminum-plastic panel core material with high strength and low water absorption.
It has high tensile strength and low water absorption.
The raw materials of A2 grade fireproof aluminum-plastic board core materials mainly include polymer substrates (such as polyphenyl ether and modified polyphenyl ether), flame retardants (such as magnesium hydroxide, kaolin, etc.), inorganic fillers (such as wollastonite, calcium carbonate, etc.) and other additives (such as chain extenders, dispersants, lubricants, etc.).
As a modified multifunctional emulsion, the water-based vinyl acetate-vinyl copolymer emulsion can be combined with these raw materials effectively to improve the fire resistance and physical properties of the core materials of aluminum-plastic panels.
Product storage:
Proper storage conditions must be maintained, such as a dry and sheltered place, preferably between 5 and 40°C.
In summary, the modified multi-functional water-based vinyl acetate-vinyl copolymer emulsion is an ideal choice for the production of A2 grade fireproof aluminum-plastic board core material with high strength and low water absorption, and its excellent performance characteristics and formula adaptability can meet the manufacturing needs of high-end aluminum-plastic board products.

The main performance
Bonding properties: modified VAE emulsion has excellent bonding properties and can be widely used for bonding paper, wood, plastics, synthetic fabrics and other materials.
Water and alkali resistance: The adjustment of the amount of ethylene monomer reduces the glass transition temperature of the copolymer, which significantly improves the hydrolysis resistance, water and alkali resistance.
Weather resistance: The modified emulsion has better weather resistance and can maintain stable performance under different environmental conditions.
Application fields
Adhesives industry: Due to its excellent bonding properties and environmental protection, modified VAE emulsions have a wide range of application prospects in the adhesive industry, such as construction, packaging, textile and other fields.
Coating industry: It can be used as the base material of interior and exterior coating, roof waterproof coating, fireproof coating, anti-rust coating, etc., to provide excellent adhesion and durability.
Textile treatment: It can be used for coating, printing and dyeing of fabrics to improve the waterproof, anti-fouling and wear resistance of fabrics.
Advantages
Environmental protection: water as the medium, does not contain or contain less organic solvents, has good environmental performance.
Versatility: Through modification technology, the emulsion has a variety of functions to meet the needs of different fields.
Good compatibility: can be mixed with most additives, such as dispersant, wetting agent, antifreeze, defoamer, preservatives, etc., to meet various needs.
