  • Biomass thermoplastic polyurethane
    Patent number: 10414852
    Abstract: A biomass-based thermoplastic polyurethane is provided. The biomass-based thermoplastic polyurethane is a reaction product of a composition. The composition includes 1-50 parts by weight of a modified lignin, 50-99 parts by weight of a first polyol, and 40-60 parts by weight of a diisocyanate. The modified lignin has an OH value of less than 3.0 mmol/g. The sum of the modified lignin and the first polyol is 100 parts by weight.
    Type: Grant
    Filed: December 28, 2017
    Date of Patent: September 17, 2019
    Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE
    Inventors: Wen-Pin Chuang, Yi-Che Su, Yun-Ya Huang, Chao-Chieh Chiang, Cheng-Han Hsieh

  • Bio-polyol composition and bio-polyurethane foam
    Patent number: 10323115
    Abstract: A bio-polyol composition and a bio-polyurethane foam are provided. The bio-polyol composition includes polyol, a surface-modified lignin, and a surfactant represented by formula 1. wherein R is represented by CnH2n+1, n is an integer of 0 to 3; x/y is between 5 and 13; a is an integer of 1 to 100; b is an integer of 1 to 100.

  • Bio-polyol composition and bio-polyurethane foam material
    Patent number: 10087298
    Abstract: A bio-polyol composition and a bio-polyurethane foam material are provided. By using the modifier and applying the dispersing and grinding process, the modified lignin is uniformly dispersed in the polyol solution and a bio-polyol composition is obtained. The obtained bio-polyol composition may be used to prepare the bio-polyurethane foam material with a high lignin content, a high compression strength and superior flame-resistance.
