Storage method

Store in a cool, ventilated and sealed place. The storage temperature range for hydroxyl terminated polybutadiene should be (-20~38) ℃. The storage period is 12 months, and it can still be used after passing the re inspection.

Product transportation

During the transportation of polybutadiene rubber, it should be avoided from rain, moisture, and direct sunlight. The polybutadiene rubber should not be mixed with strong oxidants.

What is physical characteristics of Hydroxyl-terminated polybutadiene?

 1. Appearance: HTPB is typically a viscous liquid or soft solid, depending on its molecular weight and formulation. Its color can range from colorless to light yellow.

 2. Molecular Weight: HTPB has a wide range of molecular weights, which affects its viscosity and mechanical properties. HTPB with higher molecular weight tends to have higher viscosity.

 3. Viscosity: HTPB is known for its relatively high viscosity, which changes significantly depending on its molecular weight and temperature.

 4. Density: The density of HTPB is generally in the range of 0.9 to 1.1g/cm³, depending on its formula and molecular weight.

 5. Thermal Properties: The glass transition temperature (Tg) of HTPB is typically below room temperature, which means it remains flexible at lower temperatures. Its thermal stability can vary, but it can generally withstand moderate temperatures.

 6. Solubility: HTPB is soluble in a variety of organic solvents, such as toluene, acetone and other non-polar solvents, but is insoluble in water.

 7. Mechanical Properties: HTPB has good elasticity and flexibility and is suitable for applications requiring these properties. It can be formulated to achieve specific hardness and tensile strength.

 8. Chemical Resistance: HTPB is resistant to a wide range of chemicals, including oils and fuels, making it useful in applications such as adhesives, sealants and coatings.

 9. Curing Performance: HTPB can be cured with various curing agents (such as isocyanate) to form a solid elastomer, thereby enhancing its mechanical properties and stability.

 These properties make HTPB a versatile material that can be used in a variety of applications, including aerospace, automotive, and as a binder in propellants.
