Title:
THERMOPLASTIC POLYURETHANE PARTICLES AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/164539
Kind Code:
A1
Abstract:
The present invention provides thermoplastic polyurethane particles, which are formed in a continuous matrix phase from a thermoplastic polyurethane resin and have a particle diameter of 200-500 ㎛. In a differential scanning calorimetry (DSC) curve of the thermoplastic polyurethane particles, derived from the analysis of a temperature rise of 10°C/min by DSC, a peak of the cold crystallization temperature (Tcc) is shown at a temperature between the glass transition temperature (Tg) and the melting point (Tm). The thermoplastic polyurethane particles have a compression degree of 10-20%.
