Abstract:
(EN) 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%.
(FR) La présente invention concerne des particules de polyuréthane thermoplastique, qui sont formées dans une phase matricielle continue à partir d'une résine de polyuréthane thermoplastique et qui ont un diamètre de particule situé dans la plage allant de 200 à 500 ㎛. Dans une courbe de calorimétrie différentielle à balayage (DSC) des particules de polyuréthane thermoplastique, dérivée de l'analyse d'une montée en température de 10 °C/min par DSC, un pic de la température de cristallisation à froid (Tcc) est représenté à une température comprise entre la température de transition vitreuse (Tg) et le point de fusion (Tm). Les particules de polyuréthane thermoplastique ont un degré de compression situé dans la plage allant de 10 à 20 %.
(KO) 본 발명은 열가소성 폴리우레탄 수지로부터 연속적인 매트릭스(matrix) 상으로 형성되고, 200 내지 500㎛의 입경을 가지는 열가소성 폴리우레탄 입자를 제공한다. 상기 열가소성 폴리우레탄 입자는 시차주사열량계(DSC, Differential Scanning Calorimetry)에 의해 10℃/min의 승온 분석으로 도출된 DSC 곡선에서 유리전이온도(Tg)와 녹는점(Tm) 사이의 온도에서 냉결정화 온도(Tcc)의 피크가 나타난다. 상기 열가소성 폴리우레탄 입자는 압축도가 10 내지 20%이다.
