Polyviny Butyral

English name:Polyviny Butyrai

Other name:PVB

CAS:63148-65-2

1、Physical Property

1.1General property

(PVB)resin is white spherical granular or powder,Specific gravity 1：1；filling density 0.20~0.35g/ml。

1.2Thermal Properties

Tg of the PVB is from low polymerization degree 50oC，line up to high polymerization 90oC。

1.3Mechanical Properties

PVB has good property of filming.also has good property of tearing strength,abrasive resistance,elasticity,flexibility,glossy and so on after filming;especially used as the S-LEC Film of safety glass.it will makes the glass have strong property of impact resis tance and antipenetration properties,it can not instead of other materials till now.

1.4 Chemical Reaction

Any chemical can be reaction with secondary alcohol also can be reaction with PVB.so PVB will be used with thermosetting resin together.so that it can reach the property of chemically resistant ,solvent

resistance,water resistance and so on.of course the ratio would be

different according to the type of the thermosetting resin,it can deploy different character(like hardness,tenacity,shock resistance...and so on) paint film.

1.5 Safety Properties

Pure Pvb is Non-toxic and harmless to the human body,as the solvent can be ethyl acetate or alcohol,so PVB is widely used in European countries as the ink for food container or plastic packing.

1.6 Solubility

PVB can dissolved in alcohol,ketone and ester,solubleness will be different with different solvents.pls check the solvent form for reference.generally.alcohol is easy to sissolved.only methanol is difficult to dissolved with high Butyl aldehyde;for high butyl aldehyde,it easy to dissolved with ketone and ketone solvents.PVB is easy to dissolved with cellosolve .only a part of PVB can dissolved with xylene and toluene .PVB do not dissolved with hydrocarbon solvents.

1.7 PVB Dissolved method

When use with mixed solvents,dissolved steps is put aromatic solvents at firstly(like xylene,methylbenzene) or esters solvent(like N-butyl acetate, ethyl acetateI)frstly,bending and putting PVB .after PVB disperse.swelling.adding alcohols solvent(e.g., n-butyl alcohol, ethanol, etc.),rising temperature to shorten the dissolution time;use this method.can avoid PVB to be group.(because when PVB become group,the dissolved time will increase several times).so this can increase the dissolved speed.generally the ration of Aromatic species and alcohol would be Aromatic species(weigh ratio),it can allocate low viscosity PVB
