Thermogravimetric Analysis of Composites Obtained from Polyurethane and Rubber Waste
Tested samples of composites contained polyols of the trade name Recypol® 201 and Recypol®601 received from used polyurethane foam and of rubber recyclate received from tyres in the form of a granulate of dimensions ranging from 1.5 to 2.0 mm. The percentage ratio of polyurethane glue/rubber granulate: 5/95; 7.5/92.5; 10/90 was chosen. The profiles of composites were held at the temperature of 90°C for 90 min under the load of and 2 ·106 Pa. Thermogravimetric analysis of the samples was conducted using Perkin Elmer TGA PYRIS. Measurements were performed at the temperatures from 25°C to 900°C, with heating rates of 20°C/min, 40°C/min, 80°C/min using nitrogen as the purge gas. The value of the apparent activation energy of decomposition processes of the composites is reported.
