Highlights from the infographic:
- Polyurethanes can be liquid, stretchable, pliable or rigid and can be spread, sprayed or molded.
- Markets where polyurethanes are used: energy; construction; house and home; health and safety; transportation and appliances.
- The largest percentage of polyurethanes are used in flexible and rigid foam products. Only about 3% are used in coatings and 6% in adhesives and sealants.
- The benefits of polyurethane coatings include improved product appearance and protection from environmental conditions.
- Fluorourethanes and films are two notable types of polyurethane coatings. Fluorourethanes are higher performing than non-flourinated urethanes. They are used in extremely harsh environments, like pipe linings. Films are being used more frequently for aerospace, transportation and solar applications.
- Polyurethane adhesives and sealants exhibit strong bonding capabilities, have “green strength” and reduce the need for clamping and holding of materials.
