Petroleum Resins: A Look at One of the Most Common Hydrocarbon Products and Thei
Posted by Ajinkya on April 29th, 2021
Petroleum Resins, also known as polyisocyanates, are marine lubricants used in the marine industry. This lubricant is most commonly used as a component of an oil-based product such as anti-slip mud, anti-skid floor coating, or anti-icing mud. The product is also used to increase the surface life of metals that experience thermal shock, including sheet metal, stainless steel, aluminum, and copper, as well as plastic and composites. These lubricants are often used to protect equipment from friction and thermal shock by preventing the transfer of heat between the surface and heated fluids. In fact, this lubricant is one of the few types of lubricants that can stand up to extreme temperatures, which makes it an ideal choice to protect machinery from extreme temperatures such as those encountered during shipbuilding, drilling, and mining.
Petroleum Resins has a variety of advantages over aliphatic c5 resins. Chief among these is their high solubility, which allows them to be applied at lower temperatures than aliphatic c5 resins and to have much greater adhesion to many substrates. However, since they are insoluble, petroleum-based adhesives tend to have lower melting points than aliphatic c5 resins. At high temperatures, however, both types of cement perform equally well, and it becomes more of a factor how liquid they are and not how easily they will melt. More recently, some investigators have suggested that the introduction of an extra additive to petroleum-based adhesives could increase their melting points.
Petroleum Resins also has another advantage over its competition. They are available in a variety of compression thicknesses. This again gives them the flexibility to meet the diverse needs of the various industries that use them, ranging from automotive bodywork to high-tech electronics manufacturing. In fact, recent studies indicate that the wide availability of polyvinyl esters in the U.S. and around the world is one of the biggest reasons that petroleum-based resins remain the primary choice for adhesive products. In Europe, where the competition is strong, consumers frequently consider a product type's compatibility with its intended application. Thus, esters, in which a variety of viscosity levels are possible, are often judged to be the most suitable based on their ability to be compatible with a host of applications.
While performance in some applications is improved by both types of esters, the larger polyvinyl esters offer greater flexibility in other situations. They can, for example, be used in conjunction with a cold dip coating in order to improve the surface tension of a bolt. In applications where a lower temperature is necessary, however, the performance gap between aliphatic c5 resins and petroleum-based product types becomes a significant issue. Still, the relatively low cost of production of the former and the relatively low cost of consumption of the latter (byproducts are not needed) help to offset this difference. In the U.S., there are a couple of main manufacturers of aliphatic c5 resins. One of these, Weathervane International, has been successful in marketing its product type as a synergy product between its primary resin and its thermoplastic counterpart, providing excellent corrosion protection, even at elevated temperatures.
