Prepolymer
Prepolymers are chemical compounds that are used in many different industries. They consist of a polyol and an isocyanate component that react with each other to form a partially cross-linked chemical compound. This compound is called a prepolymer.
Prepolymers are used in many industries, including the manufacture of polymers, adhesives, coatings, sealants and foams. In polyurethane manufacturing, prepolymers are used as an intermediate to produce polyurethane foams. They can also be used in adhesive production to improve the adhesion of adhesives.
One advantage of prepolymers is that they facilitate the handling and processing of adhesives, foams and other products. They can have long shelf lives, making them convenient to store and optimizing their use in production processes.
In addition, the properties of prepolymers can be altered by modifying the composition and type of raw materials used. This enables the production of prepolymers with different chemical and physical properties that are suitable for a variety of applications.
Overall, prepolymers are an important component in the manufacture of many products that are used in a wide variety of industrial sectors.
