operation suggestions
like all isocyanates, desmodur 44c is very sensitive to water and reacts with water to produce insoluble urea and carbon dioxide. in a closed container, the carbon dioxide produced will cause the pressure in the container to rise and cause danger.
when desmodur 44c is exposed to air, especially sunlight, it will accelerate its yellowing. therefore, it is recommended to store liquid desmodur 44c in a dry nitrogen environment. yellowing generally does not affect the processability of the product.
desmodur 44c is sensitive to heat and will form dimers. solid desmodur 44c is more prone to dimerization reaction at room temperature than liquid state at 45°c. therefore, solid products need to be stored below 5°c and melt gradually and quickly before use. although the dimerization rate of the product decreases as the temperature decreases, the stability is still limited even below 5°c.
solid desmodur 44c needs to be heated to ≥70°c for melting. this process will increase the formation of insoluble dimers, and may cause the barrel to deform due to the increase in temperature and pressure.

cpol innovation
cpol is a new innovative intermediate used as the structural unit of the soft segment in high-performance polyurethanes, polyetheresters and other polymers to bring excellent flexibility, tensile properties stretch and tear properties. cpol is available in a variety of different molecular weight specifications, 1000, 2000 and 2900. while maintaining the excellent mechanical properties, functionality and hydrolytic stability of polythf, the low-temperature mechanical properties and dynamic mechanical properties, especially the stretchability and tear resistance, of products based on cpol series are better than those based on polythf.

core advantages
compared with many different polyols, cpol has lower crystallinity, which results in a lower melting point of the soft segment, giving cpol a very important advantage:

better processability 高
the melting point of cpol is significantly lower than that of polythf. cpol is liquid at room temperature, which makes its use more convenient. because cpol no longer needs to be heated and melted like polythf before use, it can be used in areas such as spraying.

more prominent dynamics mechanical properties
the structure of cpol gives it significantly higher tensile properties. and the tearing performance of products based on cpol is also particularly outstanding.
