Polyvinyl Alcohol Film(PVA film)

Overview

Polyvinyl alcohol film is made of polyvinyl alcohol as the main component, adding additives such as modifiers, and processed by special technology.

PVA film is a green functional material that can be degraded into carbon dioxide and water by microorganisms in the soil in a short time which has the effect of improving land conditions.

General properties

Polyvinyl alcohol film:The density is 1.26-1.29g/cm3, the refractive index is 1.52, and it emits blue-white light after ultraviolet irradiation. Large water absorption, immersed in water can be dissolved, the moisture content of the fiber can reach 30%-50%, and the moisture content in the environment of 65%RH and 25 °C can also reach 4.5%. It can permeate water vapor, but difficult to permeate alcohol vapor, and it cannot penetrate organic solvent vapor, inert gas and hydrogen.

Applications

1.Quick soluble film: pesticide, chemical products inner packaging liner bags, cement additive packaging bags, hospital washing packaging bags, garbage bags.

2.Medium soluble film: food, cosmetics packaging bags, supermarket shopping bags, packaging cushioning air cushions, electronic products anti-static packaging.

3.Insoluble film: packaging of chemical raw materials and intermediates, packaging of daily necessities, pharmaceuticals and toys.

4.Special films: polarizing film, automotive film, windshield lamination, sanitary material manufacturing.

  • Polyvinyl Alcohol (PVA)

    Overview Polyvinyl alcohol (PVA for short), organic compound, white flake, flocculent or powdered solid, non-toxic, tasteless, pollution-free, can be dissolved in 80--90 °C water. Slightly soluble in dimethyl sulfoxide. Its aqueous solution has good adhesion and film-forming properties; It has chemical properties such as esterification, etherification and acetalation of long-chain polyols. It is a water-soluble polymer with a wide range of uses, its performance is between plastic and rubber, and its uses can be divided into fiber and non-fiber two major uses.

  • VAE Emulsion (Vinyl acetate-ethylene copolymer emulsion)

    Overview VAE Emulsion is an abbreviation for vinyl acetate–ethylene copolymer emulsion, which is a macromolecular emulsion, copolymerized by the high pressure emulsion polymerization method, after addition of emulsifier and initiator, with the vinyl acetate and vinyl monomer as the basic raw materials. VAE Emulsion is milk white or slight yellow in appearance. Vinyl acetate–ethylene copolymer is an important product in the vinyl copolymer, generally in an emulsion state with its vinyl acetate content within a range of 70%~95%, and called as VAE Emulsion.

  • PVOH (PVC Grade)

    Overview Modified polyvinyl alcohol (PVOH) is graded according to different degrees of polymerization, hydrolysis and copolymerization monomers. The modification of PVA is mainly to use the double bonds, ester groups and the chemical activity of the hydroxyl group after alcoholization of vinyl acetate to change the side chain group or structure, and introduce other monomers to become copolymers dominated by PVA.

  • Water Soluble PVA Fiber

    Overview Water soluble PVA fiber is a kind of PVA fiber made from polyvinyl alcohol through wet spinning, heat treatment and crimping-oiling in water at normal temperature. It is good in dry heat stability, physical and mechanical properties. The remarkable characteristic is its total dissolving in water at a range of temperature. This kind of PVA fiber is mainly used in Textile industry for making the yarn and cotton.

  • PVA high strength and high modulus fiber

    Overview PVA high strength and high modulus fiber takes polyvinyl alcohol as its major raw materials. It has good prosperities such as high modulus, high strength, alkali and acid resistance, heat resistance, anti-crack, anti-infiltration and so on. High strength and high modulus PVA fiber also has good compatibility with cement and other macromolecule material and can prevent the microcrack caused by plastic shrinkage of the concrete.

  • Vinyl Acetate Monomer (VAM)

    Overview Vinyl Acetate Monomer (VAM) is a colorless flammable liquid with sweet ether flavor. Melting point -93.2 °C, boiling point 72.2 °C, 47 °C (40kPa), 9 °C (6.827kPa), -18 °C (1.33kPa), relative density 0.9317, refractive index 1.3953, flash point (open cup) -1 °C. There are several different raw materials such as acetylene method, ethylene method, acetaldehyde acetic anhydride and so on. The route of ethylene raw materials is different according to the process, and there are different methods such as ethylene gas phase method and ethylene liquid phase method.      

  • Ethylene Vinyl Acetate (EVA)

    Overview EVA is a thermoplastic copolymer manufactured through the free radical polymerization of ethylene and vinyl acetate in the presence of initiating agents using the high-pressure bulk polymerization process. EVA's properties vary dramatically from one product to another depending on the content of vinyl acetate in the macromolecule. EVAs with different properties are used for different purposes.  

  • Re-dispersible emulsion(RDP emulsion)

    Overview Dispersible polymer 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 acrylate, which has good redispersibility, redispersed into an emulsion when in contact with water, and its chemical properties are exactly the same as the initial emulsion.

  • Polyvinyl butyral resin (PVB)

    Overview Polyvinyl butyral(PVB for short) is the product of acid catalysis of polyvinyl alcohol and butyraldehyde. Because PVB molecules contain long branched chains, they have good compliance, low glass transition temperature, and high tensile strength and impact strength. PVB has excellent transparency, good solubility, good light resistance, water resistance, heat resistance, cold resistance and film formation. It has high adhesion to materials such as glass and metal (especially aluminum). Therefore, it has been widely used in the manufacture of laminated safety glass, adhesives, ceramic paper, aluminum foil, electrical materials, FRP products, fabric treatment agents and other fields, and has become an indispensable synthetic resin material.

  • Polyvinyl Acetate Emulsion(PVAC)

    Overview Polyvinyl acetate multipurpose white glue series adopts the latest process and formula to produce water-based adhesives, which have the advantages of high adhesion, fast curing and easy brushing, which effectively solves the problem of low bonding strength and long curing time of white glue, and has good water resistance and moisture resistance after curing.
