What is Purethane and its applications?

Graded engineering plastics cover the spectrum of industrial usage, finding application everywhere in today’s challenging engineering projects. Superior resistance characteristics render the materials immune to the effects of seasonal showers of salt-laden water as experienced by support struts criss-crossing bridges over a raging sea. Impervious to abrasion and the wear experienced by constructs in hostile environments, components coated in these complex polymers have taken over as the ideal solution for offsetting the general drawbacks of metals. Zooming in to check out Purethane in particular, we see it has several properties that are proving invaluable in engineering projects both above and below ground.

There are countless engineering projects being managed across the globe right now, work that would have been unfeasible just a few decades ago. Let’s qualify that fact by saying the work may have been possible, but many of these engineering feats would have encountered unassailable obstacles. Ironwork would have crumbled and eroded under the assault of waterlogged soil, accelerating toward a flow-choking collapse in a few short years due to cathodic disbondment. Today’s solution of engineering plastic in general and Purethane in particular resolves these one time critical issues by replacing the age of metal with the environmentally resistant age of advanced plastics.

The application of a monolithic layer of Purethane, the trademark name for the polymer known as Polyurethane, is applied to a primed surface, and the characteristics of the polymerization process bonds the plastic to the target surface, curing the entire assembly in a matter of hours. Purethane combines the durability of strong metals with the neutral properties of plastic, defeating erosion and caustic corrosion by shielding metallic surfaces. In short, this engineering plastic is tough and immune to the elements. This opens a world of applications. For instance, the substance could potentially coat pipes stretching across wastelands, with the engineering departments heading the project left only to contact a supplier and select the matching grade of the polymer for the intended application.

Applied and cured in a period of hours or days, a Purethane coated pipe is ready to freight fast, a happy situation for any logistics department. It’s installed, depending on the grade of the polymer, underground, in direct contact with salt water, far out on oil and gas platforms, and in caustic surroundings. There’s no chemical reaction to offset, meaning the plastic will provide a perfect barrier when applied to a sewage pipe or waste facility where sulfide fumes slowly disintegrate weaker materials. A slightly different grade sporting more flexible characteristics could be applied to a concrete ramp in the same installation, again preventing the normally unavoidable disintegration of man-made assemblies.

Perhaps the ultimate solution in sealants, Purethane is capable of beating back abrasion from harsh weather and gifted with excellent electrical and chemical resistance characteristics, meaning no corrosion issues to deal with over the anticipated lifespan of the coated object. More than that, the polymer is currently manufactured to fulfill many roles, formulated as a near-metal substrate or as a rubber-like coating.
