Polyurethanes are used in a wide range of applications where durability and resistance to the natural elements are essential. Polyurethanes (PUs) are a special group of polymeric materials that are in many ways different from most of the other plastic types. They can be incorporated into many different items, such as paints, liquid coatings, elastomers, foams etc.Brenntag provides local and technical support to the all different type of PU systems and their applications.
Brenntag is well positioned product portfolio to help meet the challenges of the polyurethane industry with the dedicated sales team and expanding product portfolio day by day .
Antioxidants & UV Stabilizers
The use of appropriate stabilization systems protects not only the polyol during processing but also the finished polymer during its service life, when ongoing exposure to heat and light inevitably degrades polyurethane products. Automotive door trims, instrument panels, steering wheels, head and arm rests, window sealants, sportswear and even shoe soles are all affected by long-term exposure, causing changes in their physical or mechanical properties.
Our silicone surfactants product portfolio helps meet a variety of needs across a wide range of applications – from footwear to mattresses, automotive interiors to spray foam insulation used in refrigerators and construction. These essential additives allow you to optimize your system, solve problems and develop innovative products for your customers by:
- Improving emulsification and nucleation
- Preventing coalescence
- Stabilizing cell membranes
- Increasing ingredient compatibility and decreasing surface tension
Polyurethanes are formed by the reaction between isocyanates and polyols. Any trace amount of water will react with the isocyanate component to form CO2 gas (foaming). This reaction results in bubbling, which is undesirable in many coating applications. Molecular sieves will adsorb water without interacting with solvents or other components, thus eliminating CO2 formation and resulting in a smooth final product surface.
