“…Therefore, they are flammable according to the adopted classification. Flammability reduction of PU/PIR materials is usually achieved by adding different flame retardants, e.g., compounds containing boron, phosphorus, nitrogen atoms [71,72,73]. The lowest value of the oxygen index was noted for the M0 foam.…”

The Use of Waste from the Production of Rapeseed Oil for Obtaining of New Polyurethane Composites

et al. 2019

This article presents the results of research on obtaining new polyurethane materials modified by a by-product from vegetable oils industry—rapeseed cake. The chemical composition of rapeseed cake was examined. Rigid polyurethane-polyisocyanurate (RPU/PIR) foams containing a milled rapeseed cake in their composition were obtained as part of the conducted research. Biofiller was added in amount of 30 wt.% up to 60 wt.%. Effects of rapeseed cake on the foaming process, cell structure and selected properties of foams, such as apparent density, compressive strength, brittleness, flammability, absorbability, water absorption, thermal resistance and thermal conductivity are described. The foaming process of RPU/PIR foams modified by rapeseed cake was characterized by a lower reactivity, lower foaming temperature and decrease in dielectric polarization. This resulted in a slowed formation of the polyurethane matrix. Apparent density of RPU/PIR foams with biofiller was higher than in unmodified foam. Addition of rapeseed cake did not have a significant influence on the thermal conductivity of obtained materials. However, we observed a tendency for opening the cells of modified foams and obtaining a smaller cross-sectional area of cells. This led to an increase of absorbability and water absorption of obtained materials. However, an advantageous effect of using rapeseed cake in polyurethane formulations was noted. Modified RPU/PIR foams had higher compressive strength, lower brittleness and lower flammability than reference foam.

“…Rigid polyurethane foams are flammable materials due to their organic polymer matrix and cellular structure. Typically, flame retardants are used in PU foams to drastically reduce their flammability [47,48,49]. The flammability test of the obtained RPU/PIR foams was carried out by three methods: Limited oxygen index method, residue after combustion in the vertical test, and burning in a horizontal position.…”

New Poly(lactide-urethane-isocyanurate) Foams Based on Bio-Polylactide Waste

The article presents the results of research on the synthesis of a new eco-polyol based on polylactide (PLA) waste and its use for the production of rigid polyurethane-polyisocyanurate (RPU/PIR) foams. The obtained recycling-based polyol was subjected to analytical, physicochemical and spectroscopic tests (FTIR, 1H NMR, 13C NMR) to confirm its suitability for the synthesis of polyurethane materials. Then, it was used to partially replace petrochemical polyol in polyurethane formulation. The obtained RPU/PIR foams were characterized by lower apparent density, brittleness, and water absorption. In addition, foams modified by eco-polyol had higher flame retardancy, as compared to reference foam. The results of the research show that the use of PLA polyol based on plastic waste may be an alternative to petrochemical polyols. This research matches with the current trends of sustainable development and green chemistry.

“…To date, there have been extensive reports on numerous classes of flame retardants, such as metal hydroxide, [4][5][6] phosphorus based compounds, [7][8][9] intumescent agents, [10][11][12][13][14] boron based compounds, [15][16][17] nanofillers, [18][19][20] nitrogen based compounds, [21][22][23] as well as the incorporation of silica aerogel [24][25][26] into RPUFs. However, to the best of our knowledge, there has not been studies analyzing the physical, chemical, mechanical, and thermal properties of RPUF composites prepared with established flame retardants.…”

Although rigid polyurethane foams (RPUFs) have great thermal insulating properties such as its low density, low thermal conductivity, and high compressive strength, they have limited usage because pristine PU foams are highly flammable. Therefore, in order to have widespread applications, much attention has been invested in the discovery and study of a vast number of flame retardants. In this work, analysis on the physical, chemical, mechanical, and thermal properties of RPUF composites prepared with industrially-used flame retardants, namely tris(2-chloroisopropyl) phosphate (also known as TMCP or TCPP) and expandable graphite (EG), together with the highly promoted silica aerogel, was performed. Taking into account the overall performance, it was found that EG was the best among the three flame retardants investigated.
