Thermoplastic Dispersion Polyurethane Resins
Application:
It is used in the final finishing of leather products.
Product Introduction:
Thermoplastic polyurethane resin dispersed in water is used as a lining layer and top layer in the process of finishing leather goods and covering their surface. The properties of this category of products are much better compared to acrylic base products. In addition, they have a different base. The structure of this product consists of thermoplastic polyurethane chains.
Technical Specifications:
In thermosetting resins, due to the fact that after application, cross-links are formed and a polymer network is obtained, infinite molecular mass is obtained and minimum properties can be achieved more easily. But this is not the case in thermoplastic structures; Therefore, thermoplastic polyurethane structures must have a very high molecular mass to provide minimum desirable properties. As a result, the degree of polymerization of this product should be able to increase at least up to 100 units. But on the other hand, achieving such length of chains requires a large increase in viscosity and a decrease in processability. This makes dispersing the polymer structure in a solvent environment to be considered as a solution. If the intended environment for dispersion of polyurethane resin is water, it will be favorable both in terms of price and in terms of health and environment.
Advantages:
* Ability to customize
* Proper quality control on manufactured products
International Standards or Permission:
* Determination of solid percentage based on ASTM D-1259 standard.
* Determination of viscosity based on ASTM D-562 standard
