Pure PVB is non-toxic and harmless to human body. In addition, ethyl acetate or alcohol can be used as solvent, so PVB is widely used in printing ink of food containers and plastic packaging in European and American countries.

Storage safety properties

PVB can be stored for two years without affecting its quality as long as it is not in direct contact with water; PVB shall be stored in a dry and cool place and avoid direct sunlight. Heavy pressure shall be avoided during PVB storage.

Solubility

PVB is soluble in alcohol, ketone, ester and other solvents. The solubility of various solvents changes according to the functional group composition of PVB itself. Generally speaking, alcohol solvents are soluble, but methanol is more insoluble for those with high acetal groups; The higher the acetal group, the easier it is to dissolve in ketone solvents and ester solvents;

PVB is easily soluble in cellosolve solvents; PVB is only partially dissolved in aromatic solvents such as xylene and toluene; PVB is insoluble in hydrocarbon solvents.

Viscosity characteristics of PVB solution

The viscosity of PVB solution is greatly affected by the formula of solvent and the type of solvent; Generally speaking, if alcohol is used as solvent, the higher the molecular weight of alcohol, the higher the viscosity of PVB solution;

Aromatic solvents such as xylene and toluene and hydrocarbon solvents can be used as diluents to reduce the viscosity of PVB solution; The effect of PVB chemical composition on viscosity is summarized as follows: under the same solvent and the same content of each base, the higher the degree of polymerization, the higher the solution viscosity; Under the same solvent and the same degree of polymerization, the higher the acetal group or acetate group, the lower the solution viscosity.

Dissolution method of PVB

Where mixed solvents are used, the dissolution step is to first put aromatic solvents (such as xylene, toluene, etc.) or ester solvents (such as n-butyl acetate, ethyl acetate, etc.) into the mixing, slowly put PVB into the mixing, and then add alcohol solvents (such as n-butanol, ethanol, etc.) after PVB is dispersed and expanded,

At this time, the dissolution time can be shortened by heating; Using this dissolution method, the formation of lumpy PVB can be avoided (because the dissolution time will be several times after the formation of lumpy PVB), so the dissolution speed can be accelerated. Generally, the ratio of aromatic and alcohol solvents is 60 / 40 ~ 40 / 60 (weight ratio), and PVB solution with low viscosity can be prepared.

The solvent composition contains 2 ~ 3wt% water, which can improve the hydrogen bonding strength of alcohol solvents and help the solubility of PVB.

Processing properties

Although PVB resin is a thermoplastic, it has little processability before plasticizer is added. Once plasticizer is added, its processability is very easy.

The purpose of general coatings and adhesives is to change the resin characteristics by adding plasticizers to meet the application requirements, such as film softness, reducing the TG point of the resin, reducing the heat sealing temperature, maintaining low-temperature softness, etc.

Compatibility

PVB can be compatible with a variety of resins, such as phenolic resin, epoxy resin, alkyd resin and MELAMINE resin.

B-08sy, b-06sy and b-05sy with high acetal degree can be mixed with nitrocellulose in any proportion. PVB and alkyd resin are partially compatible. General PVB is compatible with low molecular weight epoxy resin, while high molecular weight epoxy resin needs PVB with high acetal degree to be compatible with each other.

  • The Importance of Choosing the Right Duvet Insert Size When it comes to selecting the perfect duvet insert size for your bed, it's crucial to consider several factors to ensure a comfortable and cozy sleeping experience. Not only does the right size duvet insert provide adequate warmth and insulation, but it also complements the overall aesthetic of your bedroom decor. The first step in determining the appropriate duvet insert size is to measure your bed. Measure the length and width of your mattress, including any extra inches around the edges. This measurement will help you determine the ideal size for your duvet insert. Keep in mind that standard bed sizes vary slightly, so it's essential to double-check the measurements before making a purchase. Another important factor to consider when choosing a duvet insert size is the type of bed you have. For example, if you have a queen-sized bed, you'll need a queen-sized duvet insert to ensure it fits properly. Similarly, a king-sized bed requires a king-sized duvet insert to provide ample coverage. If you're unsure about the correct size for your bed, consult the manufacturer's guidelines or contact a bedding expert for assistance If you're unsure about the correct size for your bed, consult the manufacturer's guidelines or contact a bedding expert for assistance If you're unsure about the correct size for your bed, consult the manufacturer's guidelines or contact a bedding expert for assistance If you're unsure about the correct size for your bed, consult the manufacturer's guidelines or contact a bedding expert for assistanceduvet insert size. In addition to providing adequate warmth and insulation, the right duvet insert size can also enhance the appearance of your bedroom. A well-chosen duvet insert can complement your existing bedding, curtains, and pillows, creating a cohesive and aesthetically pleasing space. On the other hand, an ill-fitting duvet insert can clash with your decor and make your room feel cluttered or disorganized. When selecting a duvet insert, it's also worth considering the fill material. Different fill materials provide varying levels of warmth and insulation, so it's essential to choose one that suits your personal preferences and needs. For example, down duvets are known for their warmth and lightness, while synthetic fill materials offer excellent warmth at a lower cost. In conclusion, choosing the right duvet insert size is essential for ensuring a comfortable and cozy sleeping experience. By measuring your bed, considering the type of bed you have, and selecting a duvet insert that complements your decor and fill material, you can create a bedroom environment that you'll love to wake up in every morning.
