Streszczenie:

There is a growing consensus that CFCs will be phased out by the year 2000. Finding other ways of blowing polyurethane foams whilst retaining their excellent insulation properties is the major technical challenge currently facing the polyurethanes industry. The most promising technical solution to date is the replacement of CFC 11, the principal blowing agent for rigid polyurethane foams, by either HFA 123 or HFA 141b. Both are proving to be viable alternatives. Significant progress has already been made in reducing substantially the amount of CFC 11 needed for foam manufacture by using a dual

Currently, most commercial polyols used in the production of polyurethane (PU) foam are derived from petrochemicals. To address concerns relating to environmental pollution, a sustainable resource, namely, castor oil (CO), was used in this study. To improve the production efficiency, sustainability, and compressive strength of PU foam, which is widely used as an impact-absorbing material for protective equipment, PU foam was synthesized with CO-based multifunctional polyols. CO-based polyols with high functionalities were synthesized via a facile thiol-ene click reaction method and their chemi

As a consequence of the high production and simultaneous consumption of polyurethanes (PU) a great volume of PU waste is landfilled. In this scenario, suitable and efficient routes for PU waste recycling have been searched for many years. In this work two series of PUs using different recycled PU sources were synthesized: a thermoplastic PU series using a glycolysated polyol obtained from the glycolysis of elastomeric PU waste (chemical recycling) and a PU flexible foam series loaded with PU dust waste created in the shaping of PU surf tables (mechanical recycling).

Open-cell spray polyurethane foams are widely used as highly efficient thermal insulation materials with vapor permeability and soundproofing properties. Unfortunately, for the production of commercial foams, mainly non-renewable petrochemical raw materials are used. The aim of this study was to determine the possibility of completely replacing petrochemical polyols (the main raw material used in the synthesis of polyurethanes, alongside isocyanates) with bio-polyols obtained from used cooking oils, classified as waste materials. The research consisted of three stages: the synthesis of bio-pol

Prior to the Montreal Protocol on ozone depleting substances, dichlorofluoromethane (CFC-11) had been widely used in polyurethane foam formulations as both a blowing agent and to endow the foam with excellent insulation properties. Now, U.S. manufacturers of products containing rigid polyurethane foam insulation must face the challenge of eliminating CFC-11 from their products. This must be done while retaining the excellent insulation properties that have made PUR foam the most effective insulation material in use today.

Currently, polyurethane (PU) production is completely dependent upon fossil oil, as the two primary reagents necessary for PU production, polyol and isocyanate, are derived from fossil fuels. Eucalyptus branches are waste products for most forest management companies. In this work, polyols obtained by the liquefaction of eucalyptus branches were used for foam production. The influence of the isocyanate, catalyst, surfactant, and blowing agent contents on the foam properties was studied.
