Long Glass Fiber Filling TPU Thermoplastic Polyurethane Composite Material

Thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, TPU for short, is A (AB) N-type block linear polymer, A is a high molecular weight (1000~6000) polyester or polyether, B is a diol containing 2~12 straight chain carbon atoms, AB chain chemical structure is a diisocyanate.

Thermoplastic polyurethane rubber is cross-linked by intermolecular hydrogen bonds or slight cross-linking between macromolecular chains. With the increase or decrease of temperature, these two cross-linked structures have reversible properties. In the molten state or solution state, the intermolecular force is weakened, and after cooling or solvent volatilization, there is a strong intermolecular force connected together, restoring the performance of the original solid. Typical TPU such as spandex.

Feature

High toughness, high rigidity, low water absorption, high dimensional stability, chemical resistance, and good product appearance.

Application

Car doors and windows, safety toe, mechanical parts, pneumatic nail gun boxes, professional power tools, nuts, bolts, etc.

Polyurethane thermoplastic elastomer is characterized by excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, low-temperature resistance, good oil resistance, chemical resistance, and environmental resistance. In a wet environment, the hydrolysis stability of polyether ester is far more than that of polyester type.
