What are the uses of flexible and rigid polyurethane foam? Polyurethane rigid foam is a high polymer made of isocyanate and polyether as the main raw …
Preface Two-component polyurethane adhesives are usually composed of an isocyanate component (curing agent) containing NCO and a hydroxyl component (m…
1、Polyether As the main raw material, polyether reacts with isocyanate to produce carbamate, which is the skeleton reaction of foam products. In the c…
The main component of polyurethane foam (PU foam) is polyurethane, the raw material is mainly polyisocyanate and polyol, by adding appropriate additiv…
In the process of foaming, if the hardness of the hard foam is not enough, how to improve the hardness? In this regard, I have collected some solution…
Influence of catalyst Since the raw material systems of polyester polyol and polyether polyol are different, there are differences in reaction perform…
