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.
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.
The manufacturing process
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.
If we compare polyurethane with metal, it is obviously more flexible, has less weight, does not conduct electricity and is less susceptible to abrasives. Polyurethane is also much cheaper to manufacture and maintain, mechanisms equipped with parts from this material create less noise. All this affects the quality and cost of the final product.
