13. Conclusions • There are obtained PU foams by industrial spraying method. • The main characteistics: • A / B ratio = 1 / 1; • Density 36 kg/m3; • Compression strength 0.21 MPa; • Lambda 18.5 mW/m K; • High dimensional stability; • Low water adsorption. • Content of lignin in ready foams up to 8%. • The thermal insulation material is comparable or better as industrially used PUR foam materials.
