The subject of research presented in this article are the semi-rigid polyurethane foams (SRFPUR) produced with a formula developed by the company FAMPUR. It consisted of replacing the petrochemical polyol with two types of rapeseed oil-based polyols of different viscosity. Foams were characterized using such techniques as infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry. With the use of scanning electron microscope changes in the structure of materials were analyzed. In addition, the apparent density, number of closed cells, and properties of materials during compression tests were determined.Na podstawie receptury opracowanej przez firmę FAMPUR wytworzono półsztywne pianki poliuretanowe (SRFPUR).
