In the past two years, textured stone veneers have emerged in many classic Taiwanese-style projects. However, due to unresolved issues regarding raw materials, cost, transportation, and construction, most people remain hesitant. However, a highly realistic imitation stone veneer-PU stone-exists on the market. This material is widely used abroad, especially in regions with predominantly wood-framed buildings, where it excels in exterior wall decoration. Despite this, PU stone is not well-known in China. This article will delve into this highly realistic imitation stone veneer-PU stone-to explore its secrets.
PU stone's primary component is polyurethane, or "pu." Polyurethane, short for polyurethane ester, is a class of macromolecular compounds with repeating urethane groups on its main chain. It is produced through the addition polymerization reaction of organic diisocyanates or polyisocyanates with dihydroxy or polyhydroxy compounds. It has wide applications and can replace various products such as rubber, plastics, and nylon.
