聚安酯(PU)

Polyurethane (PU)

This compound material is mainly utilized for coatings, making the carrier material water proof. PU can be used as a compact coating or a microporous coating. However, the coating's durability is highly dependant on the structure of the carrier material: The more even its structure, the longer the coating's life span will last. Polyurethane will be abrased after some time, losing its water proof quality. Still, Polyurethane coatings are much more durable than PVC (Polyvinylchloride) coatings.
