Properties of Polyurethanes Based on Tall Oil Fatty Acids Ester with Different Types of Flame Retardants

Abstract

To decrease the combustibility of polyurethanes based on tall oil fatty acids ester, additives of five different halogen- and phosphorus-containing flame retardants were used. The efficiency of the flame retardants was evaluated from the change in the thermal, mechanical and combustibility characteristics of the obtained polyurethanes. It has been found that the phosphorus-containing flame retardant Levagard 4090 N decreases the combustibility of polyurethane to the greatest extent.

The effect of rapeseed oil-based polyols on the thermal and mechanical properties of ureaurethane elastomers

“…The limited number of publications concerning the application properties and synthesis of EPUUs produced using rapeseed oil-based polyols results in the low commercial availability of these products. Therefore, the current modifications of commercial products are mainly limited to design changes resulting in a variety of shapes and colors of the products and the packaging, especially in the production of polyurethane foams [4], and adhesives and coatings [20]. In this regard, the introduction of new ecological products manufactured using rapeseed oil-based polyols would significantly improve their competitiveness on the market.…”
