Lithopone, a blend of zinc sulfide and barium sulfate, is renowned for its exceptional properties. It boasts high refractive index, superior lightfastness, and excellent heat resistance—qualities that make it particularly suitable for rubber compounding. When integrated into rubber formulations, lithopone imparts a pristine white color, which not only improves the aesthetic appeal of the final products but also serves functional purposes.

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.

  • Stainless braided oil lines are not limited to single applications. They are utilized across a wide range of industries, including automotive, aerospace, marine, and industrial machinery. In race cars, these lines facilitate oil circulation and cooling, significantly enhancing performance. In other sectors, they play a critical role in fluid transfer for hydraulic systems, ensuring smooth operation and reliability. The versatility of stainless braided oil lines makes them a go-to choice for engineers and mechanics alike.


  • 2. Durability Wire braided hoses exhibit excellent resistance to wear, abrasion, and fatigue. This durability extends their lifespan significantly compared to standard hoses, thus providing cost-effectiveness in the long term.


  • Factors Influencing Replacement Costs


  • Furthermore, sustainability and environmental impact are becoming increasingly important considerations in the pneumatic industry. There is a growing focus on developing eco-friendly pneumatic hoses and fittings that minimize air leakage and energy consumption. This aligns with the broader industry shift towards green technologies and sustainable practices.

  • The advantages of using ultra high pressure hoses are numerous, benefitting both operators and industries


  • 2. Soft or Spongy Brake Pedal A brake pedal that feels less firm than usual can suggest that air has entered the brake lines or that the hoses are expanding under pressure. Both scenarios could compromise braking performance.


  • Brake hoses are made of durable materials designed to withstand high pressure and harsh conditions. However, they can be susceptible to wear and tear from exposure to heat, chemicals, and environmental elements. Signs that your brake hoses may need replacement include visible cracks, bulges, or leaks. Ignoring these warning signs can lead to brake failure, which is why timely replacement is crucial for your safety.


  • Conclusion


  • Applications


  • Hand crimpers are particularly valued for their portability and ease of use. Unlike larger hydraulic crimping machines, hand crimpers can be operated manually, making them ideal for on-site repairs and installations. This mobility allows technicians to efficiently handle maintenance tasks in various environments, such as construction sites, automotive workshops, and agricultural fields.


  • For end-users, utilizing hoses that meet EN 857 1SC ensures that they are investing in reliable equipment capable of performing under the expected conditions. It enhances operational efficiency and decreases the risk of hydraulic failures, thus contributing to overall safety and productivity in industrial processes.


  • The EN 857 1SC hydraulic hose is constructed with a single layer of steel wire reinforcement, which gives it the flexibility to endure high working pressures while maintaining structural integrity. The inner tube is usually made of synthetic rubber, designed to handle a variety of hydraulic fluids. The outer cover is also made of rubber, providing resistance against abrasion, weather, and other environmental factors.
