Travel
The automobile is a kind of transportation tool that cannot be separated from polyurethane. Polyurethane exists in automobile interiors, automobile heat and sound insulation materials, tires, coatings and other vehicles.
electronic product

In addition, it is also used in optical fiber cables and printed circuits.
medical care
Polyurethane can be used for artificial heart, artificial kidney and artificial skin.
industry
Polyurethane is very common in industrial conveyor belts, film materials, drums and hoses.
Subdivide industries, polyurethane can be used in paper making, iron making, building materials and other industries.
In short, polyurethane is everywhere. To name just a few common uses, polyurethane has penetrated into every corner of our lives.
