Innovation of CPOL  
       CPOL is a new innovative intermediate used as the building block of the soft segment in high performance polyurethanes, polyetheresters and other polymers to bring excellent flexibility, tensile and tear properties. CPOL is available in a number of different molecular weight grades, 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 tensile and tear resistance of CPOL-based products are superior to those based on PolyTHF.

 core advantages  
     Compared with many different polyols, CPOL has lower crystallinity, which makes the melting point of the soft segment lower, giving CPOL a very important advantage:

 Processability is higher
       The melting point of CPOL is significantly lower than that of PolyTHF. CPOL is a 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 fields such as spraying.

 More outstanding dynamic mechanical properties 
   The structure of CPOL gives it significantly higher tensile properties. And the tear performance of CPOL-based products is also particularly prominent.

  Characteristic Parameters  

  application

> More transparent coatings, such as coatings for optical fibers.
> Products that require higher tear strength, such as professional sports shoe soles, running shoe soles, etc.
> Products with higher requirements on tensile properties, such as elastic materials, fibers, etc.
> Synthetic leather with better dynamic mechanical properties; winter textiles with better low temperature performance requirements.
> Sports products with higher requirements on low temperature mechanical properties, such as cast parts such as pulleys/rollers, TPU such as ski boots, coatings/films such as golf leather layers. Copolyetheresters with improved low temperature and dynamic properties for melt extrusions, foams and films in applications such as springs.
> PU applications requiring low crystallinity, such as shock absorbers and microcellular foams in high performance moving parts.
