What are polyurethanes?
A polyurethane is any polymer consisting of a chain of organic units joined by urethane links. It is widely used in flexible and rigid foams, durable elastomers and high p…erformance adhesives and sealants, fibers, seals, gaskets, condoms, carpet underlay, and hard plastic parts. Polyurethane products are often called "urethanes". They should not be confused with the specific substance urethane, also known as ethyl carbamate. Polyurethanes are not produced from ethyl carbamate, nor do they contain it. And if you want to know more about the polyurethane and polymer industry, see the Related Links below. (MORE)

What to do with old polyurethane?
Polyurethane are recyclable, therefore, old, used or spent polyurethane should be sorted and recycled. we need to bear in mind that it takes more than 100years for polyurethan…e products to decay. Also, they are not biodegradable. Therefore, recycling is the way forward and in the case of some special polyurethane products such as Hospital wastes and the likes, the wastes should be treated before recycling.

Is polyurethane waterproof?
Polyurethane is considered very water resistant. The degree to which the polyurethane imparts waterproofing to to something it is applied to depends on the exact chemistry use…d to polymerize it, whether a blowing agent has been used to make it a foam (i.e. polyurethane foam), and the preparation of the surface before application.

Where does polyurethane come from?
From a plastics factory. They get it by reacting a polyol with a diisocyanate in the presence of (at least!) a catalyst.
