C9 petroleum resin is a thermoplastic resin made from C9 fraction, a by‑product of ethylene production. It appears as yellow‑colored granules and features good water resistance, acid‑alkali resistance and compatibility. Thanks to its excellent gloss‑enhancing and viscosity‑adjusting properties, it is a cost‑effective choice for coatings, adhesives, rubber, printing inks and other industries. It improves hardness and weather resistance in coatings, strengthens bonding stability in hot‑melt adhesives and pressure‑sensitive adhesives, cuts costs and shortens production cycles in rubber formulations, and ensures uniform pigment dispersion in inks. After modification, it delivers more comprehensive performances and can meet high‑demand application scenarios. What other resins do you know? Follow me to learn more chemical products.
