As a product, polyurethane has many advantages over natural rubber. It is also used as a solvent in paints for a more durable coating. On the other hand, urethane is used in insecticides, pesticides and veterinary medicines. Urethane is toxic for small animals like rats and cause allergic reactions to people if it is there in medicines.
Polyurethane has lower toxicity. The basic purpose of urethanes and polyurethanes is to help make products that are stronger and more stable than their basic components. Professional Painting Knowledge Base. Better Information, Better Decisions. The name can be a very confusing part of differentiating between these coatings. You might even have polyurethane products in your mattress, shoes, or gym clothes! Polyurethane Coatings in Industrial Workplaces For industrial enterprises, polyurethane is most frequently seen in the form of coatings and adhesives.
Polyurethane coatings have many protective uses. Some major differences between polyurethane and epoxy include: 1. Elasticity Most polyurethane coatings are designed to be softer and more flexible than epoxy, without sacrificing the chemical strength industrial workplaces need.
Abrasion Resistance Polyurethane is highly resistant to abrasion, dents, scratches, chipping, and cracking. Extreme Temperatures The chemical configuration of polyurethane makes it a great selection for extreme heat or cold.
Food Handling and Bacterial Resistance Polyurethane coatings are commonly used in sensitive industries like dairy and meat processing since they are very easy to clean and cannot readily be colonized by microbes.

Many insecticides, veterinary medicines and pharmaceuticals contain different amounts of urethane. The compound is also used as a solvent. Some plastics are formed of urethane. Polyurethane is used for solid materials such as shoes and foams. Some types of polyurethane are also mixed in paints for a long-lasting coating. Urethane is toxic to small animals. People who take pharmaceuticals with urethane often experience nausea as a side effect.
Polyurethane, on the other hand, biodegrades very slowly and generally poses a low toxic risk. Steve Johnson is an avid and passionate writer with more than five years of experience. But we may not know. And many think that the only difference between the two is that polyurethane is made up of several urethane compounds. But in fact, it is not so. There exist many differences between the two compounds. The first and major difference is the number of urethane organic units in both the compounds.
Polyurethane is made up of a chain of urethane organic units joined. These polymers are formed by the polymerization reaction. The raw materials that are used to manufacture polyurethane are polyethers, polyesters, glycols, and di-isocyanates. These are the carbmic acid esters and are amides.
Polyurethane compounds are very stiff and hard. Urethane is used in many insecticides. It is also used in certain veterinary medicines and human pharmacotherapy. Urethane can be molded into different shapes and types for various purposes.
