| Résumé : |
Hydroxyl-terminated polybutadiene (HTPB) resins occupy a unique space within the landscape of commercially available polyols in the context of polyurethane elastomers. Characterized by low temperature flexibility, hydrophobicity and hydrolytic stability, polyurethane elastomers present solutions to strenuous applications in the adhesives and sealants market. Due to the hydrocarbon nature of the polymer backbone, these elastomers also have extremely low dielectric constant, dissipation factor, and moisture vapor transmission rate (MVTR) properties.
With the fast growth of the information industry, electronic products such as mobile phones, personal digital assistants and notebooks have become daily necessities for many of us. Multifunctional urethane (meth)acrylates derived from hydrogenated HTPB resins, which have excellent properties against oxidation and a relatively high refractive index of about 1.5, have gradually established their use as essential ingredients in UV-cured compositions in a clear optical index-matched adhesive for the bonding of two or more optical components together. |
