Polyurethane vs Plastic or 

First, let’s get the answer out of the way and then look into the specifics. Yes, polyurethane, like PU sheet is inherently more eco-friendly than most other plastics. It also doesn’t contain any chemicals that interfere with endocrine and hormone systems, nor does it contribute to PH change in soil or water.

But what about all that plastic waste we see in photos almost everyday? Note that most of the plastics in the shocking photos are thermoplastics, which account for over 95% of the waste seen in the oceans.

In contrast: polyurethane plastics account for less than 2%.

Stated by urethane manufacturers, one reason for this low level of waste is that polyurethane lasts far longer than most thermoplastics. This means industries that rely on polyurethane products aren’t throwing those products out as often because of wear.

Another advantage is that there are a variety of directions one can take to recycle polyurethane parts back into prepolymer constituents from which they were made.

Also, scientists use microorganisms to break downcast urethane products, and once in the environment, casting polyurethane prepolymer aren’t toxic to the environment as they break down. These facts make polyurethane more environmentally friendly plastic.

Polyurethane products, such as hot casting polyurethane prepolymer, are effective insulators, which improves the energy efficiency of buildings, thus reducing the energy required to heat and cool, and consequently lowering carbon emissions.

Properties of casting polyurethane elastomer

Technical characteristics of polyurethane make it an indispensable structural material in many industries where products must have high resistance, wear resistance, resistance to aggressive environmental influences.

Compared to rubber, polyurethane has higher wear resistance and elasticity, is not susceptible to oils, gets dirty less, ages more slowly, takes shape more quickly after deformation and better tolerates mechanical stress.
