Document Type and Number:
Japanese Patent JP6559893
Kind Code:
B2
Abstract:
The present invention discloses a thermoplastic polyurethane elastomer (TPU), and a preparation method, use and product thereof. The thermoplastic polyurethane elastomer comprises the following components with respect to the total weight of TPU: 22-55 wt % of an aromatic diisocyanate and/or alicyclic diisocyanate; 2-16 wt % of a chain extender; and 30-70 wt % of a polyester polyol. The invention can reduce a TPU injection molding shrinkage to 0.2% or less, and can increase the thermal decomposition temperature to up to 300° C., and can obtain elastomeric materials of different hardnesses, thus having a broad prospect of application in 3D printing methods.
