PVA is an atactic material but exhibits crystallinity as the hydroxyl groups are small enough to fit into the lattice without disrupting it.; Polyvinyl alcohol (PVOH, PVA, or PVAL) is a water-soluble synthetic polymer (not to be confused with polyvinyl acetate, a popular wood glue).; Polyvinyl alcohol has excellent film forming, emulsifying, and adhesive properties. It is also resistant to oil, grease and solvent. 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 plasticiser, will then reduce its tensile strength, but increase its elongation and tear strength. PVA is fully degradable and is a quick dissolver. PVA has a melting point of 230°C and 180?190°C for the fully hydrolysed and partially hydrolysed grades, respectively. It decomposes rapidly above 200°C as it can undergo pyrolysis at high temperatures.Airvol 125Airvol 165Airvol MH-82, MM-14, MM-51, MM-81Airvol SH-72, SM-73Alcotex 17F-HAlcotex 88/05Alcotex 88/10Alcotex 99/10AlkenolsAlkotexAlvylAracet apvCH2=CHOHCipoviol W 72CovolCovol 971ElvanolElvanol 20-25Elvanol 50-42Elvanol 51-05GElvanol 5105Elvanol 52-22Elvanol 52-22GElvanol 522-22Elvanol 70-05Elvanol 71-30Elvanol 90-50Elvanol T 25Enbra ovENOLEnol etherEnol ethersEnolsEthenolEthenol homopolymer, 9CIEthenol, homopolymerGalvatol 1-60GelvatolGelvatol 1-30Gelvatol 1-60Gelvatol 1-90Gelvatol 20-30Gelvatol 2060Gelvatol 2090Gelvatol 3-91GLO 5GohsenolGohsenol AH 22Gohsenol GHGohsenol GH 17Gohsenol GH 20Gohsenol GH 23Gohsenol GL 03Gohsenol GL 05Gohsenol GL 08Gohsenol GM 14Gohsenol GM 14LGohsenol GM 94Gohsenol KH 17Gohsenol N 300Gohsenol NH 05Gohsenol NH 17Gohsenol NH 18Gohsenol NH 20Gohsenol NH 26Gohsenol nk 114Gohsenol NL 05Gohsenol NL05Gohsenol NM 114Gohsenol NM 14Gosenol KH-17Gtohsenol GL 05HydroxyetheneHydroxyethyleneKuralon VPKurare 217Kurare Poval 120Kurare Poval 1700Kurare PVA 205Kurate poval 120Lamephil ojLemolLemol 5-88Lemol 5-98Lemol GF-60MowiolMowiol 26-88Mowiol 4-88Mowiol N 30-88Mowiol N 50-98Mowiol N 50/88Mowiol N 70-98Poly(1-hydroxyethylene)PolydesisPolysizer 173PolyvinolPolyvinyl alcoholPolyvinyl alcohol, fully hydrolyzedPolyvinyl alcohol, super hydrolyzedPolyvinyl alcohol, tackifiedPolyviolPolyviol M 13/140Polyviol MO 5/140Polyviol W 25/140Polyviol W 28/20Polyviol W 40/140PovalPoval 117Poval 120Poval 203Poval 205Poval 205SPoval 217Poval 217SPoval 420Poval C 17PVAPva (van)PVALPVS 4Release agent nl-2ResistoflexRhodoviolRhodoviol 16/200Rhodoviol 4-125PRhodoviol 4/125Rhodoviol R 16/20Sloviol rSolvarSumitex H 10Vibatex sVinacol MHVinalakVinarolVinarol DTVinarol STVinaroleVinavilol 2-98VinnarolVinolVinol 125Vinol 205Vinol 351Vinol 523Vinol unisizeVinyl alcoholVinyl alcohol polymerVinyl alcohol, polymersVinylon Film 2000Vinylon Film 3000Vinylon Film VF-A 2500Warcopolymer A 20C4H10O74.121674.073164942butan-2-ol2-butanol9002-89-5CCC(C)OInChI=1S/C4H10O/c1-3-4(2)5/h4-5H,3H2,1-2H3BTANRVKWQNVYAZ-UHFFFAOYSA-N belongs to the class of organic compounds known as secondary alcohols.
