The Polyester Polyols Used for Thermoplastic Polyurethane with molecular weight of 500-4000g/mol have the advantages of low chromaticity and stable activity.
The TPU made from polyester polyols has the advantages of stable viscosity, easy cutting, excellent mechanical strength, high wear resistance, tear resistance and fast molding, and can adjust molecular weight according to customer requirements.
Polyester polyol used for thermoplastic polyurethane is polyester polyol for TPU, can be widely used in TPU elastomer hot melt adhesive, shoe material, pipe, film, cable sheath, conveyor belt and other polyurethane products.
Molecular weight, hydroxyl value and acid value of our polyester polyol can be adjusted according to the requirements of the customer.
Thermoplastic polyurethane is often abbreviated as TPU.
It is a thermoplastic elastomer that can be melted.
It possesses traits of both rubber and plastic.
As a result, it demonstrates qualities including robustness, adaptability, and exceptional tensile strength.
It meets the requirements of numerous demanding applications.
These include coatings for textiles, wires and cables, sports, and automobiles.

Advantage
Thermoplastic Polyurethane can be processed easily via conventional processing methods.
These include injection molding, extrusion, blow, and compression molding.
They are easily molded into shapes to produce grips, gaskets, caps, prosthetics, and several other applications.
Drying is a critical step in ensuring TPU's process effectively and that a good part is obtained upon molding.
Remove the moisture effectively before processing.
This will allow effective drying of molded parts.
This in turn leads to a loss in properties and brittleness.
Polyester based films will have higher tensile strength and higher cut and tear resistance when compared against Polyether films.
Polyester Polymer Polyol For Tpu is the choice for shock absorption and is used widely in vibration dampening applications.
Polyether provides much higher rebound and therefore is the choice for skate wheels and high-speed rollers
