BASF is driving circular economy by making the most of the limited resources of our planet: We keep them in use for as long as possible, minimize waste and create value with renewable resources. The isocyanate can react with different chemical groups, so the final properties of the polymer will vary according to the reaction route taken. Read More. Polyurethanes are versatile materials because the chemical structure of the isocyanate and polyol starting materials can be readily changed. Although many aromatic and aliphatic polyisocyanates exist, two are of particular industrial importance. Polyurethane is obtained by mixing two main materials, polyols and isocyanates. The alkylamine group can be introduced in a polyol chain by using N-alkylaziridine or N,N-dialkyl glycidylamine as a comonomer with ethylene oxide or propylene oxide.Since the amine groups in the chain catalyze the reaction of the hydroxyl groups with the isocyanate, this type of polyol is called autocatalytic [37]. Tags: pompe volumetriche, pompe a disco cavo oscillante, resine e vernici, BMF Belli Meccanica Firenze - Via Bruno Storti, 1 - 50019 - Sesto Fiorentino (FI) Tel. TDI, MDI and Polyols are the basic materials for the production of polyurethanes. well as their polymerization with polyols. Polyurethane polymers are traditionally and most commonly formed by reacting a di- or triisocyanate with a polyol. Les isocyanates sont dangereux sous forme de liquide, de gouttelettes ou de gaz, lorsqu’ils sont inhalés ou entrent en contact avec la peau. var path = 'hr' + 'ef' + '='; Note: A hazard associated with most polyols is that—spilled material can be very slippery. Pompe a disco cavo in acciaio inox serie L-HY. The pumping of the polyol does not require any particular precautions, it is an oily liquid of medium viscosity, which has no tendency to get solid or catalyze.The pumping of isocyanate, on the other hand, presents many critical issues due to the fact that it easily gets solid in contact with air and humidity and, moreover, it’s inflammable and toxic. Thanks to this approach, post-consumer waste could be fed back into product lifecycles. The temperature at which this reversion commences is a function of the stability of the urethane structure from which reversion is occurring. After stirring for further 10 s, the stirrer was removed. When reacting an isocyanate with one or more polyols to form a polyurethane, one NCO group reacts with one OH group.

On our website you will find information on who we are, what we do, and the benefits of our products and of polyurethanes to society. For example, they can react with compounds containing active hydrogen atoms, like amines, alcohols, mercaptanes, water, and carboxylic acids or they can react with themselves to form dimers (uretdiones) and trimers (isocyanurates) or they can be polymerized to polyisocyanates (N-substituted 1-nylons). Moreover, we are dedicated to pooling our expertise on health and safety with other stakeholders, further enhancing the core structures and processes of the polyurethane industry. Typically diols or polyols (di is "two" functional and poly is more than 2) and a diisocyanate or polyisocyanate is used to prepare a polyurethane. At BASF, we understand how important it is that the ingredients you use are of the same high quality, each and every time. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available. Carbamates can be synthesized by many routes. And should you require specific advice, your sales contact is on hand to help. 1.3 MB As polyurethanes are made from the reaction between an isocyanate and a polyol, the section is divided into three parts: a) production of isocyanates b) production of polyols c) production of polyurethanes (a) Production of isocyanates.

Polyols can be reacted with isocyanates to make Polyurethane Foam, These material are ultimately used to make foam insulation for appliances i.e.refrigerators, freezers, so on. A simple mechanical seal is in fact not very reliable since the isocyanate is easily subject to solidification with consequent leakage of the seal. Les isocyanates peuvent se combiner à d’autres molécules pour donner naissance à des composés de poids moléculaire plus élevé (polymères). Therefore the formulation of a PU must take into account every possible reactive constituent. Polyurethane is obtained by mixing two main materials, polyols and isocyanates.

Polyurethane is used in a wide range of applications to create various consumer or industrial products and in the production of various common use objects. Demand for toluene diisocyanates (TDI), polymeric methylene diphenyl diisocyanates (PMDI) and polyols has considerably outpaced supply over the past four to five weeks. In addition to the polyol, polyol resin blends contain a number of additives that may be hazardous (see below), which is why users avoid skin and eye contact with the blend. Les mono-isocyanates (isocyanate de méthyle, isocyanate de phényle) sont principalement utilisés pour la fabrication d’herbicides, de biocides, d’encres d’imprimerie et de revêtements décoratifs. Clear All. var addyd992bb8554887fc5976a002a3c0a8164 = 'info' + '@'; In the case of MAG magnetic drive pumps instead, the pump is sealed thanks to the use of the magnetic coupling that avoids any risk of leakage. To the polyol component (33.80 g) isocyanate-modified lignin (optimized amount of 5.7 wt.-%, 3.42 g) was added and the mixture was stirred for 10 s by using a KPG apparatus. It is also widely used in the construction sector as insulation and in sandwich panels. This video highlights the hazards of isocyanates during the application of finish coatings. The polymeric chains built out from the initiator are usually polyethers. Polyether polyols are made by reacting epoxides with the multifunctional initiator in the presence of a catalyst. The molecular structure of the isocyanate is denominated as the HS, whereas the molecular structure of the polyol is denominated as the SS, and both regions are interconnected by a urethane bond [11–13]. Poly indicates that more than one urethane group is involved. Since polyurethanes contain two types of monomers, which polymerise one after the other, they are classed as alternating copolymers. ... beds and pillows and MDI and Polyols have been used safely in this fashion for over 60 years, If Icynene was a dangerous product we would not hold extensive BBA, European and worldwide certifications for residential applications.
