Polyurethane is a class of polymers containing urethane-type repeating structural units in the macromolecular chain. The full name is polyurethane, and the full English name is Polyurethane , PU or PUR for short.
Polyether polyols are oligomers whose main chain contains ether bonds (—R—O—R—), and whose end groups or side groups contain more than 2 hydroxyl groups (—OH). It is formed by ring-opening polymerization with low-molecular-weight polyols, polyamines or compounds containing active hydrogen as initiators, and oxidized ol...
Polyether polyols are oligomers containing ether bonds (-ROR-) in the molecule and OH groups at the end groups.
Abstract: With the continuous advancement of science and technology, polyurethane foam has received more and more attention. Because of its excellent performance, it is widely used in various industries.
【Abstract】 Polyurethane coating is a kind of synthetic material, which has good adhesion and friction resistance, and has high gloss. It occupies an important position in the current coating industry.
Polyurethane adhesive is an adhesive that can be used in a wide range. It has strong chemical adhesion to plastics, foams, glass, and metals. Today, I will briefly introduce polyurethane adhesives.
