Характеристики

Ключевые свойства и преимущества

Exhibits superior plasticizing efficiency, particularly with nitrocellulose and polyvinyl acetate, effectively reducing the glass transition temperature of polymers.
Features low vapor pressure and high boiling point, which minimizes evaporation losses during high-temperature processing stages and long-term product use.
Offers exceptional solvency for a wide range of organic dyes and pigments, ensuring uniform dispersion in various ink and paint formulations.
Provides excellent oil and grease resistance in finished plastic products, making it suitable for specialized industrial gaskets and mechanical seals.
Maintains high chemical stability under standard storage conditions, resisting hydrolysis and oxidation when protected from excessive heat and direct sunlight.

Спецификации

Технические особенности

Molecular formula is C16H22O4 with a molecular weight of approximately 278.34 grams per mole, confirming its status as a medium-chain phthalate.
Possesses a density of 1.043 to 1.048 grams per cubic centimeter at 20 degrees Celsius, allowing for predictable volume-weight calculations in batching.
Boiling point is recorded at 340 degrees Celsius under standard atmospheric pressure, indicating low volatility and high thermal endurance during manufacturing.
Maintains a refractive index between 1.491 and 1.493 at 20 degrees Celsius, which is critical for optical clarity in plastic films.
Flash point of approximately 171 degrees Celsius (closed cup) necessitates specific safety protocols regarding fire prevention and localized ventilation in workspaces.
