Polyvinyl Alcohol
Polyvinyl Alcohol Sundy PVA
Sundy PVA stands for the preminium quality in China,also for Vinylon fiber, PVA fiber, Polyvinyl alcohol(PVA), Vinyl acetate monomer(VAM), Vinyl acetate-ethylene copolymer emulsion(VAE), and EVOH etc.
POLYVINYL ALCOHOL (PVA)
PVA has many exceptional properties such as water solubility, fiber-forming property, adhesiveness, film-forming property, emulsionstability, dispersion stability, resistance to oil, acid, and alkali, chemical reactivity, biodegradability, as well as meltability (orthermoplasticity) and many unique and special properties through modification. PVA plant capacity has reached 160 ktpa with more than 60 categories. PVA is widely used in many industries like textile, papermaking, construction, chemicals, printing, packaging, pharmaceuticals, detergents & cosmetics, agriculture, ceramics, iron &steel, electronics, electrolysis, electroplating, etc.

MAIN APPLICATIONS
1. Textile
In the area of textile, PVA is primarily used as raw material of vinylon fiber and warp sizingagent. When PVA is used as raw material of vinylon fiber, it imparts the fiber with properties such aswhiteness, high strength, excellent hygroscopicity, and superior resistance to abrasion, sunlightand corrosion. Meanwhile PVA fiber can be spun in pure or in blends with cotton, wool andviscose fibers. And while PVA is used as sizing agent for textile, it won’t decompose and exhibits excellentcohesion power for cotton, hemp, polyester, vinylon and viscose fibers.
2. Pulp & Paper
PVA has found wide use in the treatment of paper surface as it hasexcellent adhesiveness and dispersibility and will not affect the property of other binders used in combination. The advantages of PVA using：Surface strength (printability)；Strength along Z-axis(paper internalstrength)；Folding resistance；Abrasive resistance； Improvedsmoothness；Improved surface glossiness；Raised resistance to oil andsolvent (barrier property).
3. Emulsion Stabilizer & Binder
PVA can be widely used as protective colloid or thickener for theemulsion polymerization of vinyl acetate (VAc) or VAc/ acrylate. has thefollowing characteristics: excellent adhesiveness；increased initial
tack and drying rate while used with filler；excellent resistance to oil；outstanding film strength；enduring and stable performance.
PVA can be used to produce water soluble film and water-resistancefilm. PVA is available in formed products which highlight the inherentfeatures of PVA, namely, high tensile strength, resistance to organic solvent and air tightness.They are both widely used in the packageindustry, not only for textile, but also for chemicals, food, dailychemicals, agricultural chemicals, dyestuff, and etc.
4. Film
PVA can be used to produce water soluble film and water-resistant film. PVA film is widely usedin textile, food, detergents & cosmetics, agricultural chemicals, and dyestuff areas owing to itsinherent features, namely, high tensile strength, resistance to organic solvent and air tightness.And also PVA is the material of polyvinyl butyral which is widely used in areas of printing ink, building glass and safety glass of automobile.
5. Dispersion Stabilizer
PVA, which is excellent in colloid protection and has superior surfaceactivity, is often used as dispersion stabilizer for suspensionpolymerization of vinyl chloride monomer (VCM). The performance of PVC resin can be greatly optimized by selecting a suitable PVA grade withproper degree of polymerization and hydrolysis.
