hiilivetyresinsit
Hiilivetyresinsit is a term used to describe hydrocarbon resins derived from carbon- and hydrogen-rich feedstocks, typically produced from C5 and C9 petroleum fractions or coal-tar derivatives. They are generally amorphous, color ranging from pale to amber, and exist as solids or viscous liquids at room temperature. The resins are characterized by a broad molecular weight distribution and a low to moderate polarity, which gives them good compatibility with nonpolar polymers and hydrocarbons.
Production and composition methods vary, but common approaches involve polymerizing reactive C5 and C9 fractions obtained
Key properties of hiilivetyresinsit include relatively high softening points, moderate to low melt viscosity, and low
Applications are broad and include tackifiers for pressure-sensitive adhesives and hot-melt adhesives, modifiers in coatings and
