HS-4483B is a kind of vinyl ester resin which is designed for rapid pultrusion molding. It has moderate viscosity, high reactivity and can greatly increase the pultrusion line speed. It can also improve product surface gloss and reduce shrinkage, reduce internal microphase crack. Pultrusion products produced by HS-4483B have great corrosion resistance mechanical properties and electrical properties. HS-4483B is especially suitable for the produce of fiber optic cable strengthening core.
