Polyvinyl Alcohol

PVA (Polyvinyl Alcohol, POVAL) is a unique functional resin that it is water-soluble synthetic polymer. Polyvinyl alcohol has excellent film forming, emulsifying and adhesive properties. It is also resistant to oil, grease and solvents. It is odorless and nontoxic. It has high tensile strength and flexibility, as well as high oxygen and aroma barrier properties. However these properties are dependent on humidity, in other words, with higher humidity more water is absorbed. The water, which acts as a plasticizer, will then reduce its tensile strength, but increase its elongation and tear strength. PVA is fully degradable and dissolves quickly.



Kuraray Tusvis

Kuraray Tusvis


Item Code: SN-series-2217-1724

Kuraray has recently developed a new aqueous polymer “TUSVISTM SN-series” based on PVA technology. SN-series has a special function group and formed big associations in water. Kuraray has developed TUSVIS through the application of the unique polymer synthesis technology that it has been nurtured through its Polyvinyl Alcohol (PVA) resin business. As TUSVIS boasts water solubility, high viscosity, high hydrophobic properties and high chemical resistance.

 

Application : It can be used as a thickening agent for eco-friendly, water-based adhesives and paints.





Kuraray Exceval Polyvinyl Alcohol

Kuraray Exceval Polyvinyl Alcohol

Item Code: RS-2117-RS-1717-AQ-4104

Kuraray has developed a water soluble polymer “Exceval" and can also be heat-melted and molded, with the original technology accumulated in Polyvinyl Alcohol (PVA) and ethylene vinyl alcohol copolymer. Among water soluble polymers, "Exceval" has unique properties and will open new application fields where the existing resins can not be used.

Fully Hydrolyzed Polyvinyl Alcohol - Polysizer

Fully Hydrolyzed Polyvinyl Alcohol - Polysizer


Kuraray Poval 117/ Polysizer 173, Kuraray Poval 103, 105

Kuraray Poval® / Polysizer
is the brand name for the Polyvinyl Alcohol produced at the Kuraray Group's sites in Asia. World's first industrial product Poval resin was industrialized as a raw material for synthetic fiber KURALON. It has a number of advantages: it is water soluble, easy to form into film, adhesive, emulsifiable, and oil and chemical resistant, among others. It is used in a wide range of applications, including as a paper processing agent, adhesive, and polymer stabilizer for vinyl chloride resins.
